The Motoron motor controllers are a family of general-purpose modules designed to control brushed DC motors. The Motoron receives commands via I²C or UART serial (depending on which model you have), so only two I/O lines are needed regardless of how many Motorons you connect.
Features and specifications
- Control interface: I²C or UART serial (depending on the model)
- I²C clock speed: up to 400 kHz
- UART serial baud rate: up to 250,000 bps
- Optional cyclic redundancy checking (CRC)
- Configurable motion parameters:
- Max acceleration/deceleration forward/reverse
- Starting speed forward/reverse
- Direction change delay forward/reverse
- PWM frequency: eight options available from 1 kHz to 80 kHz
- Command timeout feature stops motors if the Motoron stops receiving commands
- Configurable automatic error response
- Motor power supply (VIN) voltage measurement
- Two status LEDs
- Motor direction indicator LEDs
- Motoron Arduino library simplifies getting started with an Arduino or compatible controller
- Motoron Python library simplifies using the Motoron with Python or MicroPython
The Motoron motor controllers are divided into three different classes with different operating voltage ranges and maximum currents.
- Each Motoron in the 550 class operates from 1.8 V to 22 V and can provide a maximum continuous current of 1.6 A to 1.8 A per motor (depending on the model).
- Each Motoron in the 256 class operates from 4.5 V to 48 V and can provide a maximum continuous current of 1.8 A to 2.2 A per motor (depending on the model).
- Each Motoron in the high-power class has a minimum operating voltage of 6.5 V, can operate up to 30 V or 40 V (depending on the model), and can provide a maximum continuous current of 14 A to 20 A (depending on the model). These high-power models have current sensing and configurable hardware current limiting.
