Description
The WeMos I2C Dual Motor Driver Module is designed to be able to drive up to two DC motors from your WeMos mini or mini Pro development boards. Using PWM the shield is capable of independently controlling the speed and direction of each connected motor with a maximum average of up to 1.2A (3.2A peak). The shield, together with its supplied headers (3 x 10 way supplied unsoldered), allows for it to be easily inserted and removed from the WeMos Mini. Control of the shield is via the WeMos mini’s I2C interface which can be configured via solder jumpers to one of 4 I2C addresses (0x30 default). A library and example sketch is provided by WeMos to make controlling the shield from your own sketches as simple as possible.
