Assembling

This guide mainly focuses on the parts listed in the Hardware Buy guide.

Requirements

  • ESP-32
  • 433 MHz transmitter
  • Soldering station
  • Hookup wire (Optional depending if the pins line up)

What/Where to buy?

See the Hardware Buy guide here. For the board/ESP-32 assembly you need the ESP-32 and a 433 MHz transmitter.

Figuring out the PINs

Any digital output pin on your micro-controller should work for outputting the signal for the transmitter, however the default is often close to the positive and ground pins on the controller. See the boards section dedicated to the micro-controller your are using to decide which pin to use.
