Re: Wemos D1: Unable to use RX/TX pins (for hardware serial) by hobby_guy » Sun Feb 25, 2024 3:43 pm The pins I've tried to use, are RX/TX also marked "UART0" in the pinout image. Maybe I should use UART1 (or even UART2), as described here: https://www.luisllamas...
. They have the arduino pinout.The R1 and R3 have A0 buttom left .The R2 has A0 + SDA, SCL and GPIo's to Board pins are screwy, so I'd say stay with R1/R3..My WEMOS R1/R3 will support 4 relay Catalex shield directly.I am using I2c LCD using 5 volt and DS3231 using 3.3 ...

I was expecting to be able to set up digital pin 0 on the Wemos D1 Mini and have it “Just Work.” It turns out the Arduino pins don’t match up neatly to the Wemos D1 Mini pins. The path of true love, eh? Luckily,Richard Lee mapped the Wemos pins to the Arduino pinswell al...
