I want to connect the driver to the original GT2560 V4.0 Board with UART. Connector 7 is already on the Board. On the silkscreen of the Board there is only noted PDN and an empty pin, but not TX/RX._br_Can you please provide a wiring diagram of the drivers board?_br_I assume PDN is TX and [empty] is RX, but assuming something fries boards...
