Metro RP2350 take 5 🔄🌟🤞

Sometimes mistakes are made in prototyping; that's why they're prototypes. The error in rev D was funny: while making the QFN80 footprint, the pins got placed clockwise rather than widdershins. Not surprisingly, that board didn't come up at all, so here's a full rip-up and reroute, with the correct pinout this time! Fingers crossed. Hopefully, this is the final revision, and we can move on to other RP2350 boards we have cooking.

Rooooound display prototype testing 🌀✨

Okay, we've got our 1.3" round TFT prototype ready for testing - and here's a cute GIF of a dial turning back and forth. It's a great way to test the display, backlight, and SD card interface. We're using a QT Py ESP32 since we need quite a bit of oomph to decode GIFs and display them in real-time. With EYESPI, no wiring is required! This is good to go - it's time to book the PCB panel!

ESP32-P4 booting up and running CircuitPython 🚀🐍

Core CircuitPython dev Scott has been chugging away at adding ESP32-P4 support to CircuitPython - and today tossed us a bin file that runs on the Eval board we got last week from Espressif. Native USB is still in progress, but we can connect to the REPL and save files using the USB-Serial converter. It's so fast at 400mhz, and with 16 or 32 MHz of PSRAM, it's going to be an awesome board for embedded Python! More soon!

A little Espressif helper for programming

While developing boards, we often want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip

with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 to an ESP32-P4!
