87-88 Pontiac Fiero OEM Drop-In Headlight Module
About the 87-88 Pontiac Fiero OEM Drop-In Headlight Module
87-88 Pontiac Fiero OEM Drop-In Headlight Module is an open source PCB design by gekko3622, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 90 × 90 mm, with 38 components from 14 distinct parts.
Other key parts include the LM7805_TO220, CURRENT-SENSOR-ACS712#LH Door, CURRENT-SENSOR-ACS712#RH Door and Sparkfun_Pro_Micro. By type, the board carries 10 resistors, 8 transistors, 5 relays, 3 ICs, 2 connectors and 2 fuses.
From the project
An aftermarket Fiero gen2 headlight controller designed to fit into the original GM casing.
Important: Please pay attention to the Bill of Materials (BOM). Some components have been changed from my previous designs.\ This PCB MUST be fabricated with 2 Oz Outer Copper Weight for power handling and safety.
This is a PCB implementation of WalkerTexan's "Fiero Headlight Controller" project.\ I started this project after getting frustrated with the cost and questionable reliability of used modules.\ While there are new reproductions of the original module available, I found the cost to be too high.
