Waveshare RP2040 Boards: 3 New RP2040 Boards, LCD + LiPo - First Look!

[@asdhashdquwhqeiqwhe]

I was hoping for you to show the solder pad of the 10 remaining pin in rp2040 zero...

[@avsaase]

The non-standard battery connector is a little strange but I would prefer solder pads anyway. What I can't get over is that there's no switch to turn off the power to the board when you have a battery connected. How is that supposed to work?

[@john_hind]

As I found when fitting an Adafruit Feather 2040 board into a keyboard, the height of the standard battery connector is a real pain and it looks like this connector could be lower profile. But I wish they'd just use solder pads. After all you are not going to avoid soldering with any of these boards anyway!

[@demoncloud6147]

it's the CSE only ppl who don't want to solder they just like to deal with API and abstracting the hardware away

[@john_hind]

@@demoncloud6147 But these Waveshare boards do not come with pins soldered on, so you are going to have to solder to do anything useful anyway! The Adafruit ones at least have a STEMMA I2C socket as well so you can plug in a lot of sensors without soldering. Mostly with these boards, you can do some really simple stuff powering them from USB with no soldering. I suggest if you are ambitious enough to want to power them from a battery, you are probably connecting other sensors and actuators too.

Does the LCD model have Wi-Fi support? Because I am planning on making a weather station with a pi pico w and a Display and if that one has wireless functionality it would be very conver

[@wilddeveloper2021]

no

Hey, I have an RP2040-Zero and I having trouble getting the onboard RGB LED to work, Please can you do a tutorial on that? Thank you!

@@roysutton3722 ah thanks but i managed to solve it by using the neo pixel too 👍

[@SciHeartJourney]

I bought a couple of these on Amazon for low cost. I have only 1 question left about them: How do I turn my .py code into a .UF2 file? From what I've seen, this is VERY difficult. Please prove me wrong?

[@glebkutilin5676]

Добрый день, у вас получилось использовать uart на этих платах?

[@slimhazard]

As with the Tiny2040, I‘m puzzled by the RP2040-Zero’s castellated edges, on a board that isn‘t flat. The idea is that you have to foresee openings in the carrier board, so that the components on the rear side fit through?

[@MichaelKingsfordGray]

Coward.

[@james10739]

What are some ideas of things to do with the zero I mean I guess anything an Arduino can do but does it run other os's I assume

[@MichaelKingsfordGray]

The PIOs are very powerful, parallel, and independent of the two CPUs. And it is clocked much faster than Arduino.

[@samneggs1]

Very nice reviews, thank you. Could you look at the SB Components RP2040 hats particularly the Wi-Fi hat with integrated display?

[@wjn777]

It isn't the same as the Rasberry Pi Pico, is it? Blinking the onboard LED, for example, doesn't work from the built in examples

[@robertorusso3192]

RP2040-zero is compatible with arduino Ide?

[@MichaelKingsfordGray]

No.

[@wilddeveloper2021]

yes

[@IamTheHolypumpkin]

I wish they would have choosen an E-paper instead of LCD, saves so much energy, and waveshahare already sells many E-paper displays.

[@sc0or]

You can easily solder 20-pins header (or purchase it pre-soldered) and attach to number of e-ink displays with the same connector, or use an SPI/I2C. This is a matter of couple of buxes, Does not matter at all.

[@james10739]

The LCD is probably something more people would want be that would be a nice addition

[@lamda9914]

The Epaper flash too slow, I don't like it on a dev boards, LCD or OLED are more better

[@lamda9914]

And Waveshare have some E-paper displays just use cell phone NFC flash it, no power, that's awsome.

[@wickeddubz]

LilyGO T-Display has better option if you are into display projects. Small board is very important for Nintendo hacking =)

[@kattz753]

It's a shame about that battery connector. Waveshare has really built up an ecosystem with these Pico sized boards. They have esp32 S2 boards with and without screens in the same form-factor. They are compatible with the Pico hats. I have a GPIO breakout board and an ESP32 Pico board on the way from Amazon. I'm about to find out if they're compatible or I'm gonna fry some stuff.

[@diyrobotronics]

Make some projects using RP2040 boards

[@MichaelKingsfordGray]

Use a real name, before demanding effort from another.
