Note:
This board is a bi-directional I/O design with default DI mode when power on.
Before switching to DO mode, the DI pull-high jumper setting may activate active-high DO devices (e.g., 24POR
/ 24C), or the pull-low setting may activate active-low DO devices.
Please have an appropriate jumper setting depending on the characteristics of your external device.
