I can not comprehend how you would not publish a schematic of at least the I/O interface pins of the DIDO board. Are there clamping didoes to both rails? What are the values of the input resistors? What to the open collector outputs look like? What current will the outputs drive? What is the max vcc on the output pins? I won't buy another Geekworm product.
