I have further shrinked the Brushed Motor Driver board and now it measures 12.5mmX12.0mm and weighs less than 1 gram. It is capable of driving four micro brushed motors rated at 3.7v and can provide up to 2.7A of driving current. The board has built-in flyback diodes protection. This is perfect for tiny/micro/nano quad copters or any other type of small scale model aircrafts.
1. Dimension; 12mm x 12.5mm
2. Weight: 0.5 g
3. Continuous Drain Current: 2.7A
4. Max Voltage: 3.7v~5.0v
5. Works with both 3.3v and 5.0v microcontrollers.
6. Flyback voltage protection
You can order it in my store.
Here are some links to projects that use the motor board; if you happen to have used the board in your project and would like the project to be linked, please let me know.
