Features
- Double-wide socket header so you have a socket pin free on every pin for plugging in wires
- Four mounting tabs, they can be broken off if not needed
- Stemma QT / Qwiic (JST SH) connector on 3V / GND / SDA / SCL for connecting any of hundreds of displays, sensors, etc. No pullups are included on the BFF - but most boards have their own.
- 3.7V/4.2V LiPoly battery support with charging through the USB port. Will auto-switch to USB power when plugged in, and charge the battery with extra power. Charge rate of 250mA, can be adjusted to 500mA by soldering a back jumper
