Sorry these are out of stock, with no ETA. Parts required to make them have been unavailable for a years time.
This is the latest in the line of 0.4 Speeduino. It was reworked with SMD parts to make it smaller and allow for efficient machine assembly. Also the need for a ULN chip for tachometer, fan or fuel pump has been removed. The connector pins that used to be ran through the proto area have been changed to their default function. If you want to use a connection for prototype purposes, simply cut the jumper on the back and route it to the proto area.

This was a joint development between Josh Stewart and myself. Thanks Josh for having me help out!
