Pi 400 Pico Plate
=================This board connects a Pico to the GPIO header on a Pi 400, without any wires flapping in the breeze. [See the schematic here (PDF)](pi400-pico-plate.pdf).
![A pi 400 with this board plugged into its GPIO socket. A small, white, squarish board, with a pico soldered on top of it, sticking out of the pi 400. A green light is illuminated on both the pico and the pi 400.](img/plugged_in.jpg)
I made this to use at work. Besides connecting power and debug, it clearly labels the Pico pinout when viewed from the top:
![Besides the pinout labels, you can also see the labels on the three jumpers. One connects pi 5v to vbus, another connects Pi UART RX to Pico TX, and the third connects Pi TX to Pico RX](img/top_view.jpg)
- Pico VSYS is powered from Pi +5V rail
- Pico SWD is connected to Pi GPIO 24/25
- Pico RUN pin is connected to a push-button
- *(jumper)* Pico UART on GPIO0/1 is connected to Pi GPIO14/15
- *(jumper)* Pico VBUS is powered from +5V rail so Pico can function as USB hostThat's it, that's the whole thing. This repository is CC0-licensed, with the exception of the 3d models in the `3d/` directory.
The board is designed with KiCad nightly; if you don't have KiCad nightly installed, you can find pregenerated gerbers of the rev A PCB in the `gerb/` directory, which are suitable for manufacture by JLCPCB.
