Description

An arduino pro-mini shield

Details

This is a simple board to provide RF comms between a base station such as an arduino or raspberry pi to an arduino to control three servos and a switched output. It's designed to be a simple add on shield board for a pro-mini. Software works to send commands to multiple units if required and all the rx units can work as a mesh.

Getting the right voltage

Voltage Issues

One of the hassles with this and the Arduino is that the arduino is 5V and the nRF runs at 3.3v . There are a few carriers out there, but i wanted something really small and easy. So I'm using the voltage drop across a LED to power this. You'll need one of the normal size LED's and they drop just under 2v and also provide a visible indicator as it will pulse as the nRF goes about its business.

after making many robot projects I needed a simple way to contro them. It started to become too costly to use rx gear.
This uses a nRF smd chip and an Arduino pro mini and the rf24 libray which as well as providing point to point rx/tx also gives mesh capabilities with rf24mesh.
The first step was making a quick and easy two comm link with rf24 and Arduino pro mini.
