What is the difference between the MegaSquirt PCB 2.2 / PCB 3.0 / PCB 3.57?
They are all three able to use the MegaSquirt-I CPU or the MegaSquirt-II daughterboard, but they are based on different versions of the circuit board. You can click on any of the headings to view an example of the product with pictures. PCBv2.2 The v2.2 board dates back several years, it’s the least expensive of the currently available options, and the least developed. It’s a great low budget solution that has served many people well (and continues to). PCBv3.0 The v3.0 board has a lot of improvements made to it to reduce electrical noise and increase robustness, as well as make the board easier to expand. All of the improvements with the V3.0 board are listed here. The main high level differences are that the uprated flyback circuitry is included so you can run low or high impedance injectors, there are several improvements to make the board more robust and harder to damage in the event of a mis-wire or overload event. A prototyping area was adding to the PCB, and several changes were
