- You Reply: Doing something like :Code: Select allSeems like I can read the device (pm2.5 sensor), unsure if the data it is reading is correct yet
from machine import UART uart = UART(1, 9600) uart.init(9600, bits=8, parity=None, stop=1, rx=25, tx=26)
However using the UART pins as listed on the board or on the Gravity shield will still cause the ESP32 to freeze.
So there still is some issue with the listed UART. - You Reply: I have not tried mapping the RX/TX pins to another mapping.
I was using D0/D1 as the wiki lists :

let me give a go at mapping it to IO25/26 and see.
