Rahul VU3WJM has designed a single sided PCB replacement for the Raduino in a form factor of 20X4 line LCD.
In fact, this board supports both a 2 line LCD display (1602) and a 4 line LCD display (2004). Rahul has also added a few more electrolytics, separated the Analog and Digital ground plain, and the Nano module is on the component side to make it easily plugable. He has assumed mostly through-hole components but SMD pads have also been included for coupling and decoupling caps.
All fabrication files are being made Open Source for personal and club use only. He asks that you verify the Gerbers before making the board! Rahul would also welcome your feedback on any further improvements that could be made to the design.
