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. All boards come as pictured with all components including a 250kPa MAP sensor soldered on. It is your choice if the power terminal and IO connector are soldered on. If you decide you do not want them soldered, then they will be included in a separate bag with your order.
This was a joint development between Josh Stewart and myself. Thanks Josh for having me help out!
