A classic Nano board is a nice compromise between size and ease of use. No need for separate batteries but do not power the LEDs from the board, connect them directly to the battery
How many LEDs do you propose to use ? The number will influence the battery you choose
Hey,
Thx for your help.
The Led Ring has 12 leds and the led strip 40-50 leds.
Which battery should I use in your opinion? Is it possible to charge the batteries via micro usb connection from the board? I have seen a ESP32 with intern lipo Charger but I dont think that the lipo can power the leds.
