This is just a quick map to show how the pins differ on the Wemos D1 compared to the Arduino Uno.

They share the same footprint but their pins are somewhat different.

For my project I need to work out which Pins trigger the relay shield's 4 relays and also the maps for the remaining digital pins for connecting the pH sensor and temperature sensors.

the i2c pins are also required for running the oled screen and buttons.

Work is underway with the Wemos D1 code. The device will run a webserver to display data locally for users, and will also offer a json page for the Pi to collect data.

Good times!

Relays Pins:

Listed on Seeed site ad D4,-D7 on Arduino Uno.

One the Wemos it looks as though it should be pins D11-D14
