Quantities are as required for default V2.00 GPIO/MegaShift™ build, with the EGT circuits used for variable resistance or voltage input (not a thermocouple), and TIP120 transistors used on the VB921 circuits (you may need other components if you are doing a 'non-standard' build).
Note: Normally you will order a complete kit from a distributor, this BOM is provided for reference only.

Here are the other parts you'll need to build your GPIO: | Some MegaSquirt® Related Links: | ||||
Printed Circuit Board (PCB) with SMD components installed, BDM and bootloader headers installed, and serial monitor loaded, connector and harness pigtail,
LMB-Heeger case - EAS-400 - you can purchase the case from directly LMB in single unit quantities (click the link). Serial Cable: If you do not have an appropriate serial cable (such as the one from a Innovate LC-1, or MicroSquirt® EFI controller, or as supplied with production GPIO units), you will also need:
Serial Jack: Mouser KC-300416 (161-2502) - not currently available from Digi-Key. Nylon Screws: #4/40 - Digi-Key P/N H550-ND - 0.0926ea. & Nylon Nuts - 4/40 - P/N H616-ND - 0.105ea. You need 1 of each for the voltage regulator (U1), but there is a 100 minimum quantity for each from Digi-Key. You can try locally, look for them in hobby shops that sell radio control hardware. You CAN substitute steel screw hardware. Just be careful with the plastic casing, make sure the metal screws do not cut the plastic and cause a short circuit. You may want to put a dab of fingernail polish or something similar on the screw/nut interface to help prevent them backing off due to vibration. Heat sink: You will need a 5/8" x 4" (15.8mm x 100mm) piece of aluminum, 0.80" to 0.125" (2mm to 3mm) thick to make the heat sink. Jumper wire: ~20-22 gauge wire (about 4"/100mm) for making jumper connections. Normally open pushbutton switches for the manual shift functions. LEDs and suitable resistors for the gear indicators.
Ampseal Crimp Contacts and Seals: If you need replacement contacts (either gold or tin) for each of the Ampseal pins:
