Pololu Serial 8-Servo Controller (assembled)
The Pololu Serial 8-Servo Controller lets you control up to eight RC servos from almost any robot controller, microcontroller, or computer with a serial port. It accepts standard RS-232 or TTL-level serial signals with automatic baud rate detection from 1200 to 38400 bps.
Multiple controllers can be connected to the same serial line, allowing independent control of up to 128 servos. Each servo has individual speed and range control with 0.5 µs resolution (approximately 0.05°). This assembled version is ready to use — just connect power, servos, and your controller.
Key Features
- 8 Servo Channels – Control up to 8 RC servos independently
- Daisy-Chainable – Connect multiple units on one serial line for up to 128 servos
- Auto Baud Detection – Supports 1200–38400 bps automatically
- High Resolution – 0.5 µs servo positioning (~0.05°)
- Individual Speed Control – Set speed and range per servo
- Three Diagnostic LEDs – Visual feedback for power, serial, and error status
- Serial Reset – Reset via DTR or RTS handshaking lines
Specifications
- Logic Supply Voltage – 5–16V
- Data Voltage – 0V and 5V
- Servo Pulse Range – 250–2750 µs
- Pulse Rate – 50 Hz
- Serial Interface – RS-232 or TTL-level
