## Prerequisites
To be able to run all the examples successfully, you need two MicroPython-enabled Microcontrollers (Raspberry Pi Pico 1 tested) and 4 TTL-UART to RS485 converters, with two of them connected to each μController (see [[Wiring]]).
To be able to run all the examples successfully, you need two MicroPython-enabled microcontrollers (Raspberry Pi Pico 1 tested) and 4 TTL-UART to RS485 converters, with two of them connected to each μController (see [[Wiring]]).
Also, both microcontrollers should have MicroPython running on them (at time of writing this the latest tested version was 1.23.0).
If you met all these requirements, let's start wiring the parts together!

Then, connecting the A+, B- and GND wires of the respective converters together (converter 1 of μC1 to converter 1 of μC2, converter 2 of μC1 to converter 2 of μC2), you've just created a simple RS485 bus! Now upload the scripts to both Microcontrollers and try what you want to try!
