I just want a cheap one that has bluetooth LE so it can be controlled from a phone app. Does such a thing exist?

- SlowBro 9y agoESP32 sounds like it meets your needs, but it won't run Linux. It will run MicroPython though.
- megy 9y agoI will have a look, thanks!
- bschwindHN 9y agoI will second the ESP32. It's sub $4 in most places, has a dual core processor, BLE, WiFi, hardware PWM and I2C, and much more. Also their C SDK environment is quite pleasant to work in.
- tmuir 9y agoAny linux board that has a USB A port, runs the bluez stack and node js, can do this with a $5 bluetooth dongle. There's a really nice set of node.js libraries, noble and bleno, which allow you to communicate in both directions. Noble allows your linux box to be a central device, and bleno allows your linux box to be a peripheral.
