Latest Progress + Ollie v2's Testing Jig

by Ali Slim

One more week before the campaign ends. I would like to thank everyone who has backed this project. I’m preparing to start production soon. As is my tradition with all the products I release, I usually create a tester tool for PCBA testing and flashing the firmware. It’s a good excuse to make more fun gadgets!

For this project, I’ve designed a Raspberry Pi Zero 2 W carrier board with pogo pins to connect to the USB test points on the bottom layer of the Raspberry Pi, along with an onboard USB hub. I’m currently working on a script to flash the firmware and test the unit with a button press, plus there is an LED to indicate if there is any error. This will be a simple yet powerful tool to ensure production quality.
