A motor driver that enables you to control small 5V motors. A digital I2C actuator, that is highly configurable.
Application examples
- Create an interactive robot. Place two small motors with wheels, and a 3rd freely rotating wheel, on a chassis and use a WiDig with two DriveM actuators to control the motors. Add a ReachClose and map the signal to both motors and see it move as you approach it.

| Software support |
- Our EditorX software allows you to configure the digitizer to control multiple actuators simultaneously.
- We will soon release dedicated software for using this actuator. Ask us about it !
|
| Application notes |
- Make sure the actuator is plugged into the digitizer with the red wire connected to power. Reversing the plug or applying power with reverse polarity may cause damage to the actuator.
- Requires a digitizer with digital (I2C) ports, eg. the WiDig, USB-microDig or the Wi-microDig.
- The default I2C address is 100 (0x64). Both I2C lines have 1 kOhm pull-up resistors.
- Our software enables you to use most features. For more technical specs, and to find out how to control the actuator in detail, please consult this datasheet.
- The current available to drive the motor is determined by the maximum current the digitizer can provide minus the current draw of other devices connected to the digitizer. To provide a larger current, pull the pin connected to the red wire from the housing by lifting its plastic lever and connect the pin (and ground) to an external 5V power supply. The DriveM is specified as capable of driving currents up to 1 A but a heatsink (for the chip on the bottom, no screw terminal, side of the board) may be required to prevent overheating.
