Here’s a blog post about making my own Wemos D1 Mini motor controller, which includes free PCB files and the BOM to make your own It’s teeny-tiny! https://averagemaker.com/2018/09/wemoto-wemos-motor-controller.html
4wd and 4 optical encoders hanging on I2C or SPI is a perfect controller. Why nobody cares about optical encoders on the most popular 2-4WD wheels? Ok, 2 motors + 2 encoders would be enough. But then they should be stackable
@Dmitri_Nesterov Depends what you want to do I guess. I just wanted a simple way of running a couple of motors for now (for a WiFi controlled robot), so for me this is perfect (for my needs). Someone building a more advanced robot wouldn’t want something so basic. Maybe I’ll make another model in the future with some breakouts.
@LeRoy_Miller I didn’t but I may well do that just in case. Thanks!
