Today's adventure in getting data from here to there...
Two @pimoroni pico lipo 2XL W boards (@Raspberrypi RP2350B) with interconnected UARTs: 2 busio UARTs and 6 PIO UARTs each. @circuitpython asyncio code writing and reading each UART on each board:

The Pimoroni Pico Plus 2W (left) is the main microcontroller in this config, but it is getting power from the WIZnet W5500-EVB-Pico2 (right) via its WIZPoE-P1 module. The two Pico boards are attached via an @adafruit "Proto Doubler PiCowbell".
The W5500-EVB-Pico2 can run it's own code independently, even talk to the Pico Plus 2W or other external devices (except for the pins needed for Ethernet).

How to turn a $13 WIZnet W5500-EVB-Pico2 into a $5 Ethernet HAT.
@circuitpython can use both native wifi and Ethernet with this config, power and data with only an Ethernet cable (plus data over wifi).
The W5500-EVB-Pico2 is essentially just being used as an SPI Ethernet peripheral to the Pico Plus 2W (and to power the Pico Plus 2W).

Combine to make an Ethernet + Wi-Fi microcontroller config, optimizing for: performance, flash, RAM, u.FL, PoE, small size, and low cost. Not necessarily in that order. ;-)

On the road with just a phone and a @circuitpython device?
You can use your phone as a hotspot, auto-connect to it from the CircuitPython device, and use Web Workflow to access files and the serial console. Just a little pre-planning: edit the settings.toml file with the hotspot credentials.

In another episode of
"It's not April Fool's Day, but..."
Introducing: SSIDNet™️
#1 ESP32-S3 (@adafruit QT Py) using @circuitpython, creates series of Wi-Fi Access Points with SSIDs that are obfuscated partial messages
#2 ESP32-S3 receives SSIDs w/ #CircuitPython wifi Monitor mode, recomposes messages
Simple protocol assumptions: messages and fragments are sent in order, SSIDs have a 4-byte header, a 4-byte CRC is appended to the last fragment
Mis-using CAN Bus to send random-length strings of Emoji from an @adafruit QT Py ESP32-S3 with CAN Bus transceiver to an Adafruit Feather RP2040 with CAN Bus FeatherWing, using @circuitpython 8 (baudrate=500_000, 6 bytes per CAN message)

If you want to make one for yourself, I have published the 3d printable files for my Birb Air Quality sensor on Printables. https://www.printables.com/model/450447-birb-the-canary-shaped-air-quality-sensor (code coming soon!).
