Rev 3 BOM

For Rev 3 PCB

All the parts are relatively straightforward once you have the Eurorack specific sockets and vertical pots - both available from Thonk. The only tricky and critical part in Europe is the vertical SD Card Reader from Yamaichi, which I've only found available in small numbers from Acme in Italy. This part is available in the US from Mouser as part 945-PJS008U-3000-0.

NB: You will also need:

• Micro-B USB Cable - a Kindle cable works fine
• MicroSD card, up to 32gb. Teensy developer Paul Stoffregen recommends Sandisk Ultra MicroSD cards

Button colours:

• White 611-D6R00F1LFS
• Grey 611-D6R10F1LFS
• Yellow 611-D6R30F1LFS
• Red 611-D6R40F1LFS
• Green 611-D6R50F1LFS
• Blue 611-D6R60F1LFS
• Black 611-D6R90LFS

Previously it was stated that using 100k pots is ok, but it was found in testing that this could lead to CV instability.
