Micro. Squirt Module Ø Micro. Squirt encapsulates pretty much everything that Mega. Squirt 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… Ø For real engine experimenters, the Micro. Squirt PCB is offered in a module format: Ø 2 Ø The exact same circuit of Micro. Squirt is used (except ignition drivers, its logic-level output only on the module). Ø Ampseal is replaced with a 0. 1” header, two rows of 25 pins (J 2). All I/O are present on this header. Easy-to-source solution. Ø Additional processor I/O brought out on 2 x 5 header (J 1). Ø Module size is 2. 4 inches X 3. 5 inches – credit-card sized! Complete, tested module loaded with embedded Engine Control Firmware.

Micro. Squirt Module Ø I/O Header is standard. 100” (2. 54 mm) size, 2 rows of 25 pins (50 total circuits). Unpopulated. Ø Example receptacle header – Tyco/Amp 7 -534206 -5 Ø Matching pin header – Tyco/Amp 9 -146254 -0 -25 Ø 7 Standoffs are 7/16”, 1/4” Hex with 4 -40 screws (Fascomp FC 2103 -440 -A).

Micro. Squirt Module Ø 8 Micro. Squirt. Module 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: Ø USB connectivity Ø Bluetooth or Zigbee Wireless Ø On-board MAP and Baro sensors Ø On-board signal stimulator Ø Use of WBO 2 modules Ø Connector for direct plug in (EEC-IV, L-Jet, GM, etc. ) Ø Multiple modules for redundant setups, auxiliary fuel injectors, dual-fuel setup (gasoline+CNG), extended GPIO, etc. …. its up to you!

Micro. Squirt Module – Eval Board Ø 9 The Micro. Squirt Module Experimenter’s board: Ø Mounts Micro. Squirt module, breaks out all signals to screw terminals. For test and evaluation of the Micro. Squirt. Module. Ø Provision for MAP sensor, Serial DB 9, and selection DIP switches. Ø Large user prototype area and user circuit for PIC 18 F processor, CAN, LEDs, serial transceiver, 5 V power supply.
