THIS PAGE IS A WORK IN PROGRESS. FURTHER DETAILS TO COME!
There are currently 2 families of Speeduino boards available, the v0.3 line and the v0.4 line. These boards were designed to fit 2 different use cases and serve different purposes. The v0.4 line of boards is not necessarily newer/better than the v0.3, the 2 share largely the same features and capabilities. The differences are in how these are intended to be used.
As a very rough indication, the v0.3 line is best suited for retrofitting of fuel injection. The screw terminals make it simpler to connected to a bare wiring loom The v0.4 boards are intended primarily to replace OEM ECUs and hence are designed to be simpler for connector with existing connectors
