  2. MicroSquirt Module • MicroSquirt encapsulates pretty much everything that MegaSquirt has to offer, in a board the size of a business card. It would be nice to have this package for a true DIY setup… • For real engine experimenters, the MicroSquirt PCB is offered in a module format: • The exact same circuit of MicroSquirt is used (except ignition drivers, its logic-level output only on the module). • Ampseal is replaced with a 0.1” header, two rows of 25 pins (J2). All I/O are present on this header. Easy-to-source solution. • Additional processor I/O brought out on 2x5 header (J1). • Module size is 2.4 inches X 3.5 inches – credit-card sized! • Complete, tested module loaded with embedded Engine Control Firmware.

  7. MicroSquirt Module • I/O Header is standard .100” (2.54mm) size, 2 rows of 25 pins (50 total circuits). Unpopulated. • Example receptacle header – Tyco/Amp 7-534206-5 • Matching pin header – Tyco/Amp 9-146254-0-25 • Standoffs are 7/16”, 1/4” Hex with 4-40 screws (Fascomp FC2103-440-A).

  8. MicroSquirt Module • MicroSquirtModule is designed to be plugged into a Motherboard arrangement. This allows you to design your own custom PC board with any connector and accessory options you would like – here are some ideas: • USB connectivity • Bluetooth or Zigbee Wireless • On-board MAP and Baro sensors • On-board signal stimulator • Use of WBO2 modules • Connector for direct plug in (EEC-IV, L-Jet, GM, etc.) • Multiple modules for redundant setups, auxiliary fuel injectors, dual-fuel setup (gasoline+CNG), extended GPIO, etc. ….its up to you!

  9. MicroSquirt Module – Eval Board • The MicroSquirt Module Experimenter’s board: • Mounts MicroSquirt module, breaks out all signals to screw terminals. For test and evaluation of the MicroSquirtModule. • Provision for MAP sensor, Serial DB9, and selection DIP switches. • Large user prototype area and user circuit for PIC18F processor, CAN, LEDs, serial transceiver, 5V power supply.
