Pinout description
- Native USB C port : used for powering and programming the board. It allows you to charge a Li-Pol battery plugged into the JST connector.
- JST 2-PH connector connected with the Li-Pol battery charger system: Li-Pol 3.7 / 4.2 V with a capacity of 250 mAh or more can be connected to it.
- CHG LED: The LED lights while the battery is charging. When charging is complete, the LED turns off. If the packet is not connected, the LED may flash quickly.
- GND: common ground for all power and logic circuits.
- BAT: positive voltage from / to 2-pin JST socket for optional Li-Pol battery.
- USB: positive voltage from / to USB C socket if USB is connected.
- EN: 3.3V voltage regulator pin.
- 3.3 V: regulator output 3.3 V (instantaneous current 500 mA).
