Icc gateway
About the Icc gateway PCB
Icc gateway is an open source NXP PCB design by moistpope, published on GitHub. It is a 4-layer board measuring 110 × 100 mm, with 66 components from 61 distinct parts.
Its main chip is the DEV-20360, from the NXP family. Other key parts include the LMR36510ADDAR, TJA1043T/1J, TJA1051T/3/2Z, ULN2003ADR and MCP2518FDT-E/SL. By type, the board carries 22 capacitors, 15 resistors, 12 diodes, 8 ICs, 4 relays and 2 connectors.
From the project
KiCad 10 project. Sits between the car harness and the ICC (head unit) main connector J1 (Molex stAK50h 160013-0641), passes every circuit straight through except the two CAN buses, which go through a Teensy 4.1 gateway with a normally-closed relay bypass.

Schematic edits were made through the Konnect MCP tools (tools/konnectmcp.py is a stdio client for it). tools/design.py holds the full component and net table, tools/footprintstak50h.py generates the header footprint, tools/placeplan.py` the board placement.

Icc gateway: common questions
What microcontroller does the Icc gateway use?
The Icc gateway is built around the DEV-20360, from the NXP family.
How big is the Icc gateway PCB?
The Icc gateway measures 110 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Icc gateway?
66 components, from 61 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Icc gateway design files?
From the moistpope/fisker-icc-gateway repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Icc gateway design in my own project?
The repository has no license, so all rights stay with moistpope. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Icc gateway without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
