I need to have a board with an esp-01 which will already be programmed, to send a signal to another device via espnow, in the box I need to use 3 buttons which will have different functions, the board must have a connector for each button since they go inside A casing as well as the power supply will be exactly 3.3. I don't know anything about electronics but I have managed to do it very rudimentarily, I want something professional.
