This is one of the better motor driver boards I have seen.
But for me it is missing stuff.
An IMU chip - accel/gyro/compass, i2c connector for addon sensors, some servo 3 pin headers....
Ideally the addon board is about the same price as the Zero, that leaves no room for making money
Too bad the Microbit does not have the Zero footprint, it has most of the stuff needed.
Zero based robotics is still pretty expensive and/or downright ugly.
These grabbed my attention, what could you make with a dozen or so of these?
Drivers only need to be transistor arrays?
Servos cn be expensive and tricky to program , generally needinga PWM chip
I had thought a Lego compatible motor and driver and Lego shaped servo case would allow for more flexiblity.
