Note A
: 1. Adopting the 8 Pin 2mm spacing socket. Model Code: A2008WR-S-8P.
2. Direction of the signal was defined with TFT-LCD Module;
“I” refers to the signal from the user’s MCU transmitted to the TFT-LCD Module.
3. Pins with the same definition are connected together in the module inside.
4. RS232, RS422, RS485, TTL port can be default which need to point out in the order.
