Hi
We are using the DISCO-L072CZ-LRWAN1.
USART-5 uses pin PB3 for Tx, is this pin not available on the LoRa development kit ?
Is there a way to re-route the USART-5 Tx pin or access it ?
thanks

Once upon a time I made a post highlighting all the pins, but the forum transition seems to have destroyed that. There are about 3 escapable UART as I recall. You might have to split a UART to get both TX and RX from different ones.
There's a finite number of pins on the WLCSP and escaping from the Murata module.
PB3 is used internally for the Radio's SPI connection
Up vote any posts that you find helpful, it shows what's working..
