Closed donyoshi closed 3 years ago

On the pinout diagram, what does the information on the lower right mean? In particular in regards to the TX/RX pins?

If you want to interact with connected pcie modem, then you need to use mentioned GPIOs: for uart there are pins 26 and 27, then to power this device you need to pull high 25, irq is 36, power button is connected to 4 and status led (if you want to read its status) to 12. Just check example code like this https://github.com/Xinyuan-LilyGO/LilyGo-T-PCIE/blob/master/examples/SIM7600/SIM7600.ino and it should be clear for you.
