The Motoron M2S18v18 Dual High-Power Motor Controller Shield for Arduino makes it easy to control two high-power DC motors from an Arduino or Arduino-compatible board through an I²C interface. The M2S18v18 operates from 6.5 V to 30 V and can deliver continuous output currents up to 18 A per motor. This version ships with a variety of header pin and terminal block options included but not soldered in.
Stacking disclaimer: The included terminal blocks are taller than the headers, so this version is intended to be used by itself or at the top of a stack. For stackable shields, we recommend getting the kit version and soldering wires to the board instead of the terminal blocks.
The M2S18v18 shield operates from 6.5 V to 30 V (absolute maximum, not intended for use with 24 V batteries) and can deliver continuous output currents up to 18 A per motor. The M2S18v18 can be distinguished from other types of M2S shields by its smaller discrete MOSFETs and the number 150 on top of the tall silver electrolytic capacitors.
This version is a kit with the following connectors included but not soldered in. It is also available as a kit with connectors included but not soldered in, or as a standalone board without connectors.
- One 1×10 stackable female header
- Two 1×8 stackable female headers
- One 1×6 stackable female headers
- Three 2-pin 5mm screw terminal blocks
- Two 1×20 male headers (or some other configuration with a total of 40 pins)
Terminal block warnings:
1) The 5mm blue terminal blocks are rated for up to 16 A, so for higher-current applications we recommend getting an unsoldered version and then soldering thick wires directly to the board.
2) The included terminal blocks are taller than the headers, so a Motoron M2S shield assembled with 5mm terminal blocks is meant to be used as a standalone board or at the top of a shield stack. (Trying to stack multiple shields with terminal blocks can result in short circuits between the stacked terminal blocks.)
Features and specifications
- Two motor control channels allow for independent control of up to two bidirectional brushed DC motors
- Reverse-voltage protection on motor power supply
- Logic voltage range: 3.0 V to 5.5 V
- Control interface: I²C
- I²C clock speed: up to 400 kHz
- 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
- Current sensing
- Configurable hardware current limiting
- Command timeout feature stops motors if the Arduino stops functioning
- Configurable automatic error response
- Motor power supply (VIN) voltage measurement
- Optional pins make it easy to power the Arduino from reverse-protected motor power, either directly or through an external regulator (not included)
- Two status LEDs
- Motor direction indicator LEDs
- Motoron Arduino library simplifies getting started using the Motoron with an Arduino or compatible controller
- Size: 65 x 51.3 mm (2.56? × 2.02?)
- Weight: 25 g
- Channels: 2
- Model: Motoron M2S18v18
- Control interface: I²C
- Minimum operating voltage: 6.5 V
- Maximum operating voltage: 30 V. Absolute maximum; higher voltages can permanently destroy the motor drivers. Recommended maximum is approximately 24 V, which leaves a safety margin for ripple voltage on the supply line. Not recommended for use with 24V batteries.
- Continuous output current per channel: 18 A. Typical results at room temperature with both channels running at 90% duty cycle.
- Reverse voltage protection?: Y
- Connectors soldered?: N
