## 1.6 Servo Expansion Board
### 1.6.1 Introduction
The servo expansion board is fully compatible with the Micro:bit V2 mainboard. It has an onboard slot for four AAA batteries, five SK6812 RGB LEDs, and four sets of standard 3-pin peripheral interfaces with a spacing of 2.54mm. Besides, it can expand to RGB LED light strip and control 3 servos.
**DIP Switches:**
- **The right one:**
- **ON:** The power is supplied by the battery box.
- **OFF:** The power supply is cut off.
- **The left one:**
- **RGB:** The Micro:bit V2 board can be programmed to change the colors of the five onboard SK6812 RGB LEDs. Moreover, the 3-pin interface on the pxl-bxt can also be connected to the SK6812 RGB light strip to control its colors.
- **SERVO:** The Micro:bit V2 board can be programmed to adjust the angle of the external servos at 3-pin interface of SERVO3.
- **Note: The SK6812 RGB LED and SERVO mode are multiplexed. Please switch to the corresponding mode according to your need.**
### 1.6.2 Parameters
- Operating voltage: 3.3V ~ 6V (recommended onboard power supply: 4 AAA batteries(1.5V each), with the nominal total voltage about 6V).
- Standby current: About 60mA (excluding peripherals).
- Maximum output current: About 600mA (affected by the battery internal resistance and load, the peak value varies from battery brands and conditions).
- Maximum power: About 3.6 W (6V × 600mA; actual value depends on the load).
- Operating temperature: -25℃ ~ 65℃
- Dimensions: 64mm × 58mm × 21mm
- Weight: About 28.1 g (the battery holder is included, batteries and Micro:bit V2 board are not).
- Environmental: ROHS
- Interfaces and resources:
- Onboard SK6812 RGB LED × 5 (programmable full-color).
- 3-pin servo interface × 3 (SERVO1/SERVO2/SERVO3, standard GND/VCC/SIG 3-pin).
- General 3-pin 2.54mm interface × 4 (GND/VCC/SIG, GND/3.3V/D-out).
- Interface for SK6812 RGB LED strip × 1 (GND/3.3V/D-out).
- Insert four new AAA batteries, paying attention to the correct polarity.
- Connect external devices:
- RGB expansion: Connect the programmable RGB module to the 3Pin interface (note the DIN direction).
- Servo expansion: Connect the servo signal wires to SERVO1/2/3 (brown/black = GND, red = VCC, orange/yellow = SIG).
- DIP switch settings:
- Switch the right-side power to ON to enable power supply.
- Switch the left-side to RGB or SERVO according to your application mode.
