First you get the PCB panel, then you get the tester, then you get the Matrix 🔌🧠🔬
We are gettin' really really close to putting the new Matrix Portal S3 https://www.adafruit.com/product/5778 into the shop, here's a tester we use to burn in the self-test code. The RP2040 brains https://github.com/adafruit/RP2040-Based-Tester-Brains-PCB resets the S3 into the ROM bootloader, the sends over compressed binaries via USB. when the self-test starts up it notices that it's in the test jig and performs a self test of the GPIO and voltages. once done, it turns into a demo board that has a basic matrix display output for users to verify functionality. This way we only have to program the board once!
