Bill of Materials - Digi-Key Order Form

MegaSquirt® V2.10 GPIO w/ MegaShift™

This is the V2.10 GPIO component parts ordering form for Digi-Key. It will allow you to assemble the V2.10 GPIO Board with just a printed circuit board (PCB) with the SMT components installed, the items in this bill of materials, and a case. Note that some additional parts will be required, as noted near the bottom of the form.

Quantities are as required for default V2.10 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.

To order complete the following steps:

  1. Verify that you have the quantities you want for each item below.

  2. Then send your order to Digi-Key:

    You will be redirected to Digi-Key to confirm your order items and quantities. (Go to Ordering Homepage and "CREATE NEW ORDER" if you want to start over with an order after you have submitted it.)

  3. Finalize your order by clicking on the 'finish order' button on the Digi-Key site. Verify your order, payment method, and shipping details. The order will not be complete until you have finished this step.

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 HdB Electronics (650-368-1388) in single unit quantities. These are tall cases that will fit both a MegaSquirt® and a GPIO board.

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 Cable, CP-254CS-ND, $5.04
  • DB9 Serial Connector. 4109FE-ND, $3.36
  • DB9 Serial Connector Hood, 976-09RPE-ND, $1.39
