Multi-Unit Packet Serial Wiring
In packet serial mode up to eight Roboclaw units can be controlled from a single serial port. The
wiring diagram below illustrates how this is done. Each Roboclaw must have multi-unit mode
enabled and have a unique packet serial address set. This can be congured using Ion studio.
Wire the S1 and S2 pins directly to the MCU TX and RX pins. Install a pull-up resistor (R1) on
the MCU RX pin. A 1K to 4.7K resistor value is recommended.
