The first PCB

So with the majority of the code complete, and with the requirements for the transmitter part of the project finalised, I can now design the PCB for the transmitter module. The requirements are that it needs to house the Atmega328P-PU (the Arduino chip), as well as crystal, it also needs to bring in the data from 2 CP2102 USB to UART convertors and take data out to the nRF24L01 transceiver:

 

So this is the design, it’s been ordered from the fabricators, and I’ll be waiting impatiently for a few weeks while it’s made and delivered! You can look at the schematic here on 123D Circuits.
