Simple cheap small board: NRF52 ?

Post by djipey » Thu Jun 11, 2020 4:11 pm

Hi,

I know that similar questions were asked before, but after browsing quite a lot of threads on the forum, I couldn't find exactly what I need. In short, I would like to find a board that matches all these conditions:

- cheap (< 10 €)
- has bluetooth
- small (something like 20x30 max)
- has 2.54 mm pins (so it can be soldered directly on a perfboard)
- has at least one ADC
- can run micropython, of course

The bare ESP32 could match this description, but the pins are very close together. Trying to solder it on/to a perfboard inevitably means soldering it to an adapter, and then the overall bundle isn't small anymore.

I was able to find something that matches my requirements (I think) here: https://www.aliexpress.com/item/3284765 ... hweb201603_

And I know that micropyhton runs on the NRF52.

WHat do you guys think? Do you have any other board in mind that matches my requirements?

Cheers

Hi,
I would go with the Ebyte E73-2G4M04S1B nRF52832, easy to solder, comes with an external low power crystal and cheaper. It has only 512KB flash but you can run most of you python code on it. Ebyte's dev board E73-TBB nRF52832 is probably what you're looking for.
