The Micro:bit plugs in and drives up to three servos from 3 AA batteries; P0, P1 and P2 stay free for a sensor.
2Use it
| Pin or leg | What it is for |
|---|---|
| Servo 1, 2, 3 | 3-pin plugs on P8, P15 and P16 |
| Battery box | 3 AA batteries, with a switch |
- Slide the Micro:bit into the slot.
- Each servo plug goes on its 3 pins with the brown wire on the GND side.
- Switch the batteries on: the servos need them.
- With radio or Bluetooth on, drive the servos with servo write pin (P8, P15, P16).
Good to know: A 3.3 V ultrasonic sensor (HC-SR04P, Kitronik 46114) works from its pads with no divider: VCC to 3V, Trig and Echo to P1 and P2. The classic 5 V HC-SR04 does not: the board has no 5 V.
