Tiny receiver - Schematic
Help me by sharing this post

This is the simple schematic I've used for this project. First, we need the basic configuration of the ATMega chip, and for that we need the 16MHz resonaror, a few resistors for pullups and some capacitors. On the bottom left part of the scheamtic we have the configurations of the two H bridge ICs and on the right, a small MOSFET with a pulldown. On the top left corner we have the supply input and some pads for the NRF24 SMD radio mdoule. To get a lower voltage for this radio mdoule that works at 3.3V more or less, I've used just a simple diode.
