Anyone know of any small, low-cost, battery powered programmable boards for Bluetooth LE? I've got the Pi 3 and CHIP is ordered, but I'd love something smaller

Anyone know of any small, low-cost, battery powered programmable boards for Bluetooth LE? I've got the Pi 3 and CHIP is ordered, but I'd love something smaller if possible. Thanks!

I'd suggest the Intel Edison. Take a look here, note that there's a battery block: https://www.sparkfun.com/categories/272 https://www.sparkfun.com/categories/272 (Of course, it can also do WiFi, but I imagine BTLE will be thriftier on power.)

It's not out yet but the ESP32[0] has Bluetooth. It's small and super cheap. [0] https://espressif.com/en/products/hardware/esp32/overview https://espressif.com/en/products/hardware/esp32/overview

Adafruit Feather 32u4 Bluefruit LE has an Atmega32u4 (same as Arduino), LiPoly charger and BTLE built in for $30. I'm cheap, so soon I'm going to have a go at reflashing a $3 HC06 module with the RN-42 firmware [1], and using that with a $3 Arduino Pro Micro and a $1 TP4056 Charger board for the same capabilities but messier. I always learn more by messing around though. [1] https://mitxela.com/projects/bluetooth_hid_gamepad https://mitxela.com/projects/bluetooth_hid_gamepad
