Two New Electronics Kits
One of the reasons for my fairly sporadic posts on this blog is that I’ve been busy in the lab working on new boards. Here are 2 new designs for the RepRap Project.
Sanguino Breakout Shield
This is the Sanguino Breakout Shield board. It is primarily intended as a shield for existing Sanguino boards, but we’ve also included the footprint for a full Sanguino on the PCB as well. Its up to you as the builder to decide what shape the board should take: You can build it as a single board with an integrated Sanguino, or you can add headers that allow you to plug an existing Sanguino into the board. its your choice! You can buy both the full kit or the bare pcb from the RRRF store.
GM3 Noise Suppressor
This circuit will suppress electrical noise generated by many small, brushed DC motors. It was designed to fit on the GM3 gearmotor that the RepRap project uses as its extruder motor of choice. This noise suppression helps keep the noise down in the electrical system, where it might cause bad effects (such as reading quadrature signals, i2c signals, etc.) Nophead has done a nice evaluation of the board on his blog. You can buy both the full kit or the bare pcb from the RRRF store.

Been looking forward to the sanguino breakout for weeks! Just sent in my order. Great work!
