Pinout
| Pin | Description |
|---|---|
| VIN | Can be used as input or output. As input, supply 5V–12VDC to power Electron. As output, ~4.8VDC (max load 1A). |
| RST | Active-low reset input with 10kΩ pull-up and 0.1µF capacitor. |
| VBAT | Supplies RTC, backup registers, and SRAM when 3V3 not present. Can be externally powered (requires internal resistor removal). |
| 3V3 | Outputs 3.3VDC (max 800mA). Not for input power use. |
| WKP | Active-high wakeup pin; also GPIO, ADC input, or PWM. |
| DAC | 12-bit Digital-to-Analog output (DAC1). Also GPIO or ADC. |
| RX / TX | UART RX/TX, also GPIO or PWM. |
| D0–D7 | Digital GPIO; D0–D3 can be PWM outputs. |
| A0–A7 | 12-bit ADC inputs and GPIO; A6 = DAC, A7 = WKP, A3 = second DAC. A4/A5 can be PWM. |
| B0–B5 | B0/B1 digital only; B2–B5 ADC + GPIO; B0–B3 PWM capable. |
| C0–C5 | Digital-only GPIO; C4/C5 support PWM. |
| VUSB | USB 5V supply. Outputs 5V when USB plugged in. |
| Li+ | Internally connected to LiPo battery positive terminal. |
