If you want make it smaller, You can remove buttons and the USB and have an external USB connection when you upload new software. Power can be handeld in many ways depended on need.

So I know this was a year ago and I haven't watched any of your more recent videos yet, but as the buttons aren't used much a way to remove them could be just to have a pad on the edge on either side that you can simply short across with a pair of tweezers?

Where is the wifi antenna, how wireless connection will work?

Really cool, I'm trying to design something similar myself right now (using ESP32-S2) to make something like a smart pen (screen + 3 buttons + micro usb)

any chance to buy the schematics for the pcb?

Hi. We like to use several loggers for measuring barometric pressure in the field in a seed dispersal by dust devils research. From where can we order it? it seems to be out of stoke tindie and lectronz...

That looks pretty neat. Two questions: 1 - do you need to pull the SD card to read what it has logged or is there a web interface via the ESP32 that lets you do that? 2 - RTC is nice, but can the ESP32 check/sync the time using NTP? Thinking about using this for testing out battery performance on a CR2032 in different situations. I suppose you could simply use the ADC and read the voltage at different intervals?

That's a wonderful projet i wish i could have one already to try it out!! Maybe built an enclosure for it and use it in the field. I would be interested into taking the data to the next level and over internet. do you think it's possible with your device ? or do i need a specific device that connects over LAND.

I did not understand where was that very moment, when the Wi-Fi connectivity was lost? Isn't the antenna inside the chip under the black package cover?

Bro this thing is sick. Good job.

can we use this as a hid device interface can be controlled over wifi or bluethooth if so can we replace this with type c connector

Do we need the buttons, what if there were just points we could jump our selves to act as buttons... - and once deployed, we wouldn't be using the buttons any more. What about ditching the buttons and USB port, but adding two solider points for a wire antenna to be added. And print on a flexible filament PCB (flex PCB) - if you do, this and sell these I would very much buy them.

Very good board. But it's so expensive. I use a lolin S3 Pro, cheaper and works fine. Thank you.

Can u use the integrated display and a monitor connected to hdmi at the same time ? I watched reviews for pro version, that one turns off the display when using a monitor.

Well technically the ESP32 stayed the same size... Ill see myself out, thanks.

despite the tremors, but it is a great idea! 😉

Hello, I would like to know if you share the schematic, because I would like to try to make one similar :) thanks

Use seed studio esp32 s3 camera board in pen Please sir

I am trying to get into microcontroller PCB design like you do, but I don't have enough skills to do it. Do you have any suggestion on how to go about it? Thanks

The best data logger should behave as usb key when attached to usb computer port 😂.

Looks like the board is out of stock? Great concept.

A very good morning to you Paul, l require your expertise & guidance with this project as I feel well out of my depth on the logger. I've been trying to build a humidity/ temperature logger with your little Bee and am struggling to make any headway with my very limited coding knowledge. The system uses TMP117 temperature sensor and a Adafruit SHT45 humidity/temperature with I2C. I did manage to load an example onto the logger however it didn't show any of the sensors and it ran way to fast for my needs, but it did write date, time, day, onboard temp and battery to the SD card, l couldn't get back in to correct my faults as PORT, "NO PORTS DISCOVERED " or "Could not open COM3, the port doesn't exist", I had purchased a couple of those bad boys so l decided to try another one, this one on upload, "Unknown COM3"; Output, "A fatal error occurred: "Could not open COM3, the port doesn't exist" and Autoplay CIRCUITPY(D:) down in the bottom righthand corner of the laptop screen, I do get the lights on the board and the sensors. I have run a program with the two sensors, I2C, Aduino Uno and CSV file, your logger is a little smaller than the laptop, less obtrusive and somewhat much leaner on power. The sketch I'm trying for has date, time, day, humidity/temperature (SHT45), temperature (TMP117), battery and a sample rate of one hour & 40 minutes, that battery should sample into the next millennium. Any assistance would be most appreciated. Kind regards Tony h

I had this problem with mirroring in Kicad also just with 64ish connections because I didn't check :(

¡Qué buena idea y construcción de una placa todo en uno!!!. Hice un datalogger todo por separado y ahora estoy viendo como junto todo para reducir su tamaño. Esta placa se ve fenomenal. Felicitaciones!!!

Nice bro. It's dik size for you lol

Hi, what are the maximum pcb dimensions and maximum placing area? I have a 390mmX200mm board, placing area is 348X170mm. Can i place with this machine? Detailed answer is important for me, thanks..

Awesome video, this is very useful.

Will this mod work with the A10M GT2560 V4.1B Control Board?

I have a question : can you show us the schematics and the components to make a PCB with an esp32 ? Thanks you so much for this video

Hey i am working on ESPC3-mini N4 , i am strugulling to flash , can you guide me how i can do it, i used gpio9 to low to keep it in programming mode but still no use

great!

So flipping impressive!

Great concept. I look forward to your v3 with the suggestions implemented. Of interest to me are having an onboard antenna and more GPIO pins available. It would be handy if the parts were all on one side and pins exposed via catellations so it could be installed flush on another board. I like the suggestions of ditching the USBC and switches to make more room, as those can be connected via castellations. A companion dev board can be made to hold the castellations (with friction, like FlexyPins that I saw on hackaday) and breakout the USB, buttons and GPIO for prototyping & programming. For even more GPIO, could have SMD pads on the bottom side. I found your video while I was researching tiny ESP32 options I might use for a Bluetooth to PS/2 keyboard adapter. I don't think I can use an S3 in this case because I need classic Bluetooth for compatibility with most keyboards, so ultimately I need a classic ESP32 in tiny form. For this particular scenario it just needs to handle 5V power, GND and two GPIO from the PS/2 connector and I would only need temporary USB for serial monitoring and programming. I enjoyed your video on what's possible. :)

Why has no one mentioned anything about PCB origins? Why does no one mention anything about the 8mm that they don't work in PICK TEST mode if your size is 8mm or above? Why I cant see any videos about setting the positions of the components? especially the fiducials that they will never work.

is the whole base metal? beneath the mat

Fantastic. Do you get any WiFi or BLE at all?

Hello are this for sale?

amazing

I suppose you're not up for sharing the schematics. I'm an experienced programmer who's relatively new to electronics. I'd just be interested to see what passives are required for a minimally functional ESP32-S3

Good morning Paul, an excellent package on your datalogger and well done.Can you tell me; does your logger "automatically scans, detects, configers and log various Qwiic sensors" such as TMP117 temperature sensor and the Adafruit SHT45 humidity/temperature sensor, Sparkfun DEV-16832 OpenLog Artemis is OK with the TMP117 but is not happy with the Adafruit SHT45. Kind regards Tony H.

could the "USB FINGER" opton also have an antenna on the opposite side ?

yes i want to see it... and type c =D

Could you share more about how to do the PCB design?

Hi, I'm new and would like to know how to get MQTTUsername and MQTTPassword? Thank you.

I hesistate between that NeoDen YY1, and the LumenPNP. Would anyone knowledgeable please give me his opinion, in terms of reliability / performance / capabilities.

I think you can do better by integrating a chip antenna! I am currently designing an nRF52-based 10x14mm PCB, and it looks doable. I hope to get it soldered for me, though it should be solderable by hand as well.

Thanks for your info, it is really valuable. I'm looking for a machine which can change nozzles automatically or it has four heads. This one seems to be built good, I like how the reels hide under it, but it seems really slow so I don't know. Also editing stuff on that screen seems hard. Lacking end switches I can hardly believe. I would buy SMT330-LX but it's out of stock (it has nozzle changer). Currently I have a machine from Qi-He, TVM802B. This had uses some old MS webcams for vision and it hardly finds fiducials and doesn't align the components very well, so I'm looking for an upgrade. Any suggestions are welcome.

What is the actual optical zoom? From talking to the vendor the numbers given are solely digital magnification, which is most of the times useless? Also what is the FOV, did you buy extra lens? I want to replace a keyboard connector on an older MAC probook..Please elaborate. Thanks!

with easyEDA no library issues

This is amazing. Good job Paul
