Hello, I have a problem with connecting Grove - Wio-E5 via UART to RPI 4B. When I connect it, nothing happens or lights up. My exact connection:
Module TX → RX Raspberry Pi (GPIO 15)
Module RX → TX Raspberry Pi (GPIO 14)
GND to GND
VCC to 3.3V
There is voltage in the system (I checked it with a meter). What could be the problem?
