Sanguinololu PCB v1.3a
Professionally manufactured PCB version 1.3a of Sanguinololu (SL) with dual sided silkscreen and through-plated holes. This is just the PCB, no components mounted!
SL is a simplified version of RAMPS, and the Arduino was integrated into the PCB! This gives you a complete solution for the price of what normally would be just the shield! With this board, you do NOT need an Arduino Mega anymore.
