OPSX

An open sourced Polaroid SX-70 core board

This is an open sourced Polaroid SX-70 instant camera core board with the Raspberry Pi RP2040 as the MCU. The aim of this project is to provide a fully resource accessible and hobbyist friendly replacement core board. It offers more extensibility and hacking ideas while implementing all the features of the original camera.

The structure of the repository:

1. The bom folder contains an html-based interactive bill of material. You can use it to find the component types and locations

2. The code folder holds the program files necessary to run the core board. The programs are implemented in two separate programming languages:

   • Micropython: Similar syntax to python, easy to modify and testing.
   • Rust (TODO): Ultimate performance with zero runtime loss.

3. The gerber folder stores the PCB files necessary for factory production.

4. The schematic folder holds a PDF file which illustrating the circuit principles.
