Why is ESP32 better than Arduino?

[@cmxpotato]

There are legitimate downsides to the ESP32 not mentioned. It's terribly inaccurate for analog read (especially when WiFi/Bluetooth is running), draws 3-10 times the power than other modern microcontrollers, its PWM is software emulated so it's unusable if you need precise and accurate PWM. Just some things to be careful about because some of these are dealbreakers for some projects.

[@notyourtipicaltechguy6438]

They forgot power consumption as well... The Arduino is more power efficiënt in general, and are easier to get into lower power consumption sleep as well, another plus is the Io count of atmel chips as well...

[@NoName-zx1qo]

stm32 is better than both

[@romanbengaldrole4061]

Actually it uses little power when the WiFi and Bluetooth are off. I didn’t have problems with PWM or analog and you can set the pins to be UART, I2C or SPI and it still works. For WiFi, I could make it work with radio, wifi and PWM at the same time. However, one thing to know is that it’s harder to code (with an Apple computer it is quite long to set up the software), and it easily burns as the voltage regulators aren’t like on an Arduino. For example a radio module with no capacitors is a problem with these…(smaller arduinos can’t handle it either)

[@goranjosic]

It depends on application. I'm a hobbyist, so I never use the same microcontroller for every project. When I only need to read and send data (e.g. via 433mhz network), attiny85 is irreplaceable, consumes little and does everything necessary. If you need to run the display and do other things at the same time, and the RPi is too big, then the esp32 is the best option, but as someone below said, analog reading is bad, consumption is huge, etc. it has its downsides... (many people, including me, never use its low power core, because it is complicated to program)

If you have a powerful computer, of course it won't take long to upload a program to an ESP32. However, if you have an average desktop or a cheaper laptop, it will take significantly longer to program an ESP32 Vs an Arduino. It's a 32 bit dual core machine. I like that the Arduino has grouped pins for specific purposes, and you don't necessarily need a pinout map, to be sure you can use the pin that you want to use. Also, the Arduino operates in 5 volts. Many hall effect sensors, motor controllers, and PWM LED controllers only work properly with a 5 volt signal. Of course, you can control an Arduino with an ESP32, using the analog inputs.

The STM32 is great for software based applications like smart devices or connectivity. Where Arduino Micro Pro is superior to hardware based applications, like motor controllers, analog input readout controller and very low power controllers. Two different purposes really, not better overall than other.

[@andreyturkin]

@@paristo Strongly disagree. You have a point when comparing against esp32 but stm? Stm32 in particular has a very large lineup of devices which are extremely capable in various areas. You can have a software solution which is orders of magnitude better than atmegas. You can have a timer suite _specifically_ designed for motor controller applications with hardware-sustained advanced features - which is much better than (AFAIK) atmegas can do; on analog input you could do a lot with ADCs, including things like simultaneous capture of multiple inputs or, say, multiplexed capturing so you could have a whole lot of inputs - again, hardware-assisted so cpu core doesn't have to orchestrate all of that in irqs or anything, just needs to deal with ready data. Very low power controllers? Stm32 got that covered as well with their L series, so does TI with their msp430 and others do as well - they'd perform at least on par with atmels.

[@Username9182736451]

I used the esp32 as the ecu in an EV. Worked pretty well. Yes, the ADCs are noisy. But i was able to talk spi to a 2 port CAN board, and control motors with LED library. The biggest challenge with arduino and esp32 is fiddling with Billy Bob's library to make it, lets say, industrial. I wasnt sure about how to use the second spi port. So you have to proceed with paranoia about everything. Always keep a working example. Always do automated testing. I wish I could confidently hook up as many spi devices as I want and a esprog hardware debugger effortlessly. I think it's possible, but certainly not easy. I had it working at one point, but a year later I couldn't figure out that debugger again. I don't think the no pwm output/measurement in hardware is a legit critism. There is dedicated hardware. Also it has a built-in CAN interface, which handy for automotive products. The one I bought had a display i used to display the firmware version and debug stuff. I had plans to control it over wifi or Bluetooth, but never got around to it (like, e.g. let me summon my car!).

I have 20..30hz by wifi get.

An Arduino is wonderful for remote sensor applications that either don't need a data connection or are able to connect in other ways. They're great for repetitive tasks that don't require much processing overhead. ESP32 is enough to run an entire mac classic emulator with CPU to spare. It's overkill for many applications. It's nice, though, if you need the power, or just don't care about power utilization or code optimization.

[@wil9861]

Can someone list the academic courses or topic one would need to get into self taught electronics

[@SamGib]

Not everything needs WiFi or BT. In fact, I try to avoid them due to security and stability.

[@SERAVIVA]

How did you... levitate it...

[@majdai]

But i faced a lot of problems using esp32 more than Arduino

[@tommarekcz]

one issue I am experiencing is slow compiling time in arduino ide.

[@balee15]

for heavy industry only PIC, AVR, Z80 etc....

[@Scorponox93]

would've been great to know this in january when I had to do an arduino project for a class which then turned into an iot project...

[@IronMeDen1]

I need an arduino and a bunch of dupont cables and doing some weird manually timed pulls to even be able to get a connection for my ESP32 and I still haven't managed to get code onto the thing. Most likely a skill issue though.

[@MorgothCreator]

ESP8266 and ESP32 are still quite unstable, you can't rely on them yet, the application can freeze or crash, they need to do more worl on the low level WiFi libraries to make them more stable.

[@sh4n940]

A problem that i noticed when i worked with esp32 if you want to use esp-now and other protocols that use wifi probably you will get some errors, esp-now is over wifi.anyway ESP32 the best board for IoT

[@mapagmasidtv]

Thanks robert now i understand i have to buy an esp32 developement kit too

[@SvRider512]

What are projects everyone is doing with these boards?

[@JaySharma_javascript]

I want something which reads precise analog signals. Any suggestions?

[@ugetridofit]

A/D converter

[@SupernovaSpence]

I heard that it’s better than arduino because of Wi-Fi Wi-Fi Wi-Fi… great argument 👍🏻 let’s just forget about the trade offs… like power, pwm, dac’s, adc’s etc

[@randysteven88]

I wish there was a ESP32 with 54 digital input/output (or more) like the Ard. MEGA.

[@timmy7201]

The ESP32 is a bare-bones microcontroller, Arduino is a proto-board platform based on various types of microcontrollers. There is a big difference between those two! I'm going to use an ESP32, whenever I must design something that requires wifi and less than a dozen IO pins. I'm not going to use an Arduino, when the design requires no wifi but 90 IO pins! In that case I'm just using an At-mega6490, or I will look at what Microchip and TI have to offer. Arduino is not a type of microcontroller, but a toy platform meant for kids and students!

[@Hukkinen]

ESP32 dev boardgames abundant though

[@RaphaelM-MG]

What about RP2040? Is it a strong competitor or not?

[@mariocosta2050]

Depends on what we can do. To Kill a flie we don't needs an RPJ-7... That is the case, we have to keep the things Simple as possible...

weird question. why car is better than bicycle or plane? different things are for different tasks dooh

any one have the same experience in compiling arduino ide for the esp 32, which taking so long?

[@leovillant768]

Arduino still doesn't eat a whole lot of battery tho

[@armonfrohlich6348]

The problem I have with clips like this is that only people who don't know anything about it and are looking for information watch videos like this. And they get completely incompetent advice or are misled... First of all, Arduino is a brand, not a specific product. So does the creator want to claim that an Esp32 is better than, for example, an infrared shield? Or a shield for motor control? Better than any product that Arduino offers? Even if it was a vase? Channels like this should really be banned because they are misleading. Apart from that, the right tool for every job. If I wanted to build a device for on the go, for example, I would definitely choose an Arduino controller. These are known for their robustness, among other things. They are also not as prone to failure as the Esp32, which is also annoying if there are certain other devices in the vicinity, such as microwaves or similar, or a device that is supposed to detect fields. Besides, what do I want with double or even five times the power when the Mini's is more than enough? What's the point? Cars are being compared to tricycles... In addition, the warning in the manual that you should work within the brand is not (just) there for greed. Firstly, you cannot use every Arduino shield on the esp32. With Arduino controllers, this works across the entire product range. In addition, even the esp32 uses the advantages of the Arduino shields and the IDE. Without Arduino, there would be no esp32.... but what I consider to be the third point (besides being more reliable and robust) is that you can easily replace the controller. No soldering, no fiddling around... just use a pair of tweezers or something similar to pry the chip out and insert a new or different one, depending on the project. Then there is the community, the tutorials and so on... yes, the esp32 has more power. But if you don't need that, you don't need an esp32, right? How about a clip like "when an esp32 is better than such and such an Arduino controller".

[@baller-qw9bb]

or for about the same size u can get a RPi zero 2 W it has wifi and the chip runs at 1.1GHz

[@wtmayhew]

Of course the Arduino Uno R4 Wi-Fi has an ESP32 SoC processor, so you can have both at once.

[@daze8410]

esp32 was hard for me to get into because I did not know any programming before, still iffy on C but micropython is an option for a lot of boards

[@AnotherCG]

You cannot compare these like that. Arduino is a movement platform. ESP is also part of the Arduino platform

[@rickhunt3183]

The application dictates the hardware. While I gravitate towards the esp32. I primarily try to focus on the raspberry pi pico as it natively runs in python and its very easy to upload to since the host see's it as a flash drive. One thing to consider is that the Arduino uses 5 volt logic and most sensors do as well. There's absolutely nothing wrong with using the AT328 microcontroller. If your primary focus is on cpu speed. You might want to rethink your application, algorithm or both. Consider splitting up the application processes over multiple microcontrollers for best efficiency. I've written lots of machine code that ran at .89 MHz and 1 MHz without any problems and you can too.

[@Industry-insider]

That 240 MHz one is also a dual core

[@ugetridofit]

and the new P4 is dual core 400mhz

[@TurdBoi666]

​@@ugetridofit this ratio is dual core

[@JimnyVR5]

also it's 3.3V which is a pain if you got an Arduino heavy environment

[@ugetridofit]

If your still working with 5v your back in the horse and carriage days.

[@x7heDeviLx]

I think both are needed the more hobbyist electronics the better

[@OlafFichtner]

ESP32 is a microcontroller (board), Arduino is a microcontroller platform. You can use boards with ESP32 on that Arduino platform. Apples and oranges...

[@FieldSobrietyTest6676]

Arduino walked so ESP could run. They're cool at their own times. That's technological improvement.
