Coming soon – Petite Pico Prototypes – QT Py RP2040

Qt Pico Rev A Bottom Breadboard

Qt Pico Rev A Breadboard

Can we squooosh an RP2040 into a QT Py shape? With double sided assembly and some 0402 resistors…yes! We stuck to 0805 and 0603 for the supply bypass caps, but went smol for the resistors and 20pF’s…but it seems to all fit! there’s two buttons and neopixel on top plus of course a QT connector and silk. Bottom has the chip, flash, crystal and lots more capacitors. The pads are castellated like our SAMD based QTPy but it doesn’t render right. Silkscreen next!
