Control electronics for Pinbot test jigs

Pinbot is an open-source platform for quickly building test jigs for electronics QA. The platform is made up of mechanical fixture, control electronics (this repo), jig-level software and backend to store all test results.

It features: - 16 channels GPIO (0-24V) thru TCA9535 - 8 channels ADC (12 bit, 0-24V) thru ADS1015 - 4 signal relays - USB hub - 4 downstream ports (3 USB-A + 1 as a pins on J2) - Per-port power control - Per-port fault signals for error and power failures handling - Qwiic connector for easy I2C expansion - Raspberry Pi 40-pin GPIO header with SPI, I2C, UART, etc - USB-C…

Pinbot electronics: common questions

What microcontroller does the Pinbot electronics use?

The Pinbot electronics is built around the HC-1.0-4PWT, from the Raspberry Pi family.

How big is the Pinbot electronics PCB?

The Pinbot electronics measures 114 × 65 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Pinbot electronics?

204 components, from 68 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 Pinbot electronics design files?

From the Pinbot-factory/pinbot-electronics 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 Pinbot electronics design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which Pinbot-factory chose for the repository.

Can I test firmware for the Pinbot electronics without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
