Adding a battery
- My unit did not come with a battery
- Added an SMT mount ST connector to the board
- Added an 850 mAh LiPo battery
- The pinout on the card was backwards from the pinout of the connector at the end of the battery wires
- Removed the pins from the battery wire connector and flipped the pins
- Charging works
- Battery is a bit too thick to screw the back on completely
- Switched to longer standoffs
- Someone else's page (they added an inline connector and wired to the card)
Software
Test Jigs
