The Pulse Train HAT

A Raspberry Pi HAT

The PTHAT mainboard has a single channel pulse train output and limit switch input. Ideal for single motor control.

Adding the expansion board to the mainboard expands the PTHAT to have 4 channels and also extra I/O functionality.

Both that mainboard and expansion board have been designed to simply connect to the Raspberry PI.
