Which board should I buy for...

Post by abutler »

Please suggest a board that will meet the requirements

- BLE
- WiFi
- Powered by 4 AA batteries
- low power consumption
- Arduino IDE compatible

On a related issue, you should add a way to search for boards based on feature sets when shopping.

Regards,
Arthur

Arthur,

The ESP32-C3 opens up the opportunity to use BLE and WiFi together. It can also be powered from AA's and is Arduino IDE compatible.

However, BLE support is new to the ESP32's so expect some challenges as support builds for these.

Thank you for the quick response. I like that board, but the additional requirements are:

- 1 ADC
- 1 digital output to control a relay.

Can you suggest a board that will meet these requirements?

Same board. The ESP32-C3 has 4 ADC's which also be GPIOs. Plus additional GPIOs on top of those.
