Hi!
I’m working on a project and looking for recommendations on an Adafruit / Arduino compatible board. The project is quite simple - control three LEDs over BLE / Bluetooth
Must have:
- BLE / Bluetooth
- Lower power consumption - runs off a LiPo battery for a week
- Drives three 3V LEDs at 20ma for 8 hours a day
- Connect over BLE / Bluetooth from Windows / Mac without a specific Bluetooth dongle (native Bluetooth on PC / Mac)
Nice to have:
- Recharge battery over USB
- Monitor battery level
- Over the air firmware updates
- Ability to switch in to low power mode / idle state
Initial thoughts are Adafruit Feather nRF52 Bluefruit LE - nRF52832 Adafruit Feather nRF52 Bluefruit LE - nRF52832 – Pimoroni
Any and all suggestions welcome - thanks!
