(TECH) Touchscreen Xadow connection clarifications

[chao.zhang]

Hey all, I’m just wondering about a clarification.

On the Wiki page for the touchscreen ( seeedstudio.com/wiki/Xadow_1 … ouchscreen ) the connectors are described as:

Connector:
2 × 35 PIN Xadow Connectors for Xadow GSM+BLE & Xadow Audio

So, is the “audio” side of the screen really just for audio only? And must the other side be connected only directly to the cellphone module? Are there pins that aren’t passed-through the LCD, or is that merely talking specifically about and labeled for the “RePhone”-specific use of that screen?

Thanks!
Adam

Hi Adam,

For clarification, all the modules with dual 35Pin connectors, such as Xadow 1.54’’ touchscreen, Xadow Audio and Xadow GSM Breakout, they all have to be connected in the right orientation, check the following image:

The Xadow 1.54’’ touchscreen does not have unfilled corner, so instead you can regard the “phone” side as the starting end.

So the Xadow GSM+BLE has to be connected on the “phone” side, while the Xadow Audio and Xadow GSM Breakout are more flexible, and does not have to be on the “audio” side.
