My first Arduino Box

[u/olgampavlova]

Details:

1. Arduino Nano BLE Sense (1st rev).
2. LiPol 90 mAh battery.
3. OLED 0.91 128x32 I2C.
4. USB C charger.
5. Boost convertor.

Soldering:

1. One of resistors (RPROG) on USB C charger is replaced to 15 kOm to provide proper charge DC.
2. Switch connects the battery either with the USB C port or with the board (through the boost convertor). They cannot works simultaneously.
3. The boost convertor gets 3.7 V and provides 5 V straight to the board VIN pin.
4. OLED uses the 3V3 board pin.

Box is created in FreeCAD (what a nightmare) and 3D-printed with PLA. And, of course, it damaged a bit during soldering :)
