TTL_RX, and TX Pin Configuration fro SDC2150

8 years 2 weeks ago #29527263 by houshun.poh
Hi,

I am trying to design a board that breaks out the header connector for the SDC2150.

I am trying to connect a bluetooth module to the TTL_RX, and TTL_TX pins.

I was wondering is the order of the pins reversed?

Which is the correct configuration?

1.

RX(Bluetooth) -> TTL_TX(SDC2150)
TX(Bluetooth) -> TTL_RX(SDC2150)

or

2.

RX(Bluetooth) -> TTL_RX(SDC2150)
TX(Bluetooth) -> TTL_TX(SDC2150)

I did not manage to find any documentation on the pins configuration.

Thanks you very much
