Arduino UNO-shaped ESP32-P4 + ESP32-C6 board. cnx-software.com/2026/10/26/… @Adafruit Metro ESP32-P4 Hydra board features 16MB PSRAM, 16MB NOR flash, WiFi 6, Bluetooth 5.3 LE, Thread, and Zigbee connectivity (through the ESP32-C6), as well as Raspberry Pi-compatible MIPI DSI and CSI interfaces, a USB 2.0 port, a microSD card slot, and Arduino UNO expansion headers. The board can be programmed using the ESP-IDF framework or CircuitPython 11.0 (Alpha version), and Adafruit is working on Arduino support.

The RP2040 Feather with USB Host lets us use Intellikeys with an iPad the Intellikeys is a popular accessibility device with custom overlays, that is no longer supported. even though it has a USB plug it doesn't work like many USB devices: it doesn't enumerate as an HID keyboard, instead it downloads the firmware from the computer driver! that means it'll never work with many modern devices ike chromebooks or iPads...unless you've got a specialized device like the RP2040 Feather with two USB ports! we've loaded Thach's Intellikeys translator (github.com/adafruit/Adafruit…) arduino sketch and it even does overlay detection so that when we switch out the paper it will enumerate as a different HID device. the code and hardware is all open source, so it can be maintained and improved for a very long time.

Just released a new version of #USBvalve firmware (0.7.0): github.com/cecio/USBvalve I moved on the latest version of TinyUSB. This is the first step to implement a #badusb detector as suggested during the talk @1ns0mn1h4ck Stay tuned for news on this!

The Kolibri firmware now doubles as a UART to USB CDC bridge, so a separate USB-UART PMOD is no longer needed. The Eis computer will also get this feature soon. @TinyUSB is great! github.com/machdyne/kolibri

One step closer to Metro M7 feat. iMX RT1011 and ESP32! The first board of a new chip series is always the toughest because we have to figure out all the gotchas and testing techniques.

rp2040 programming an rp2040 ~ flash inception we crank out a lot of @Raspberry_Pi rp2040 microcontroller boards and so we have to be able to program them very fast and very reliably. historically we used a teensy 3.6 to run our programmer+tester 'brains'

using tinyusb and arduino to make a USB mass storage floppy 💾 drive -we got on-the-fly mfm decoding working so we have fluxes converted to bytes, and all the sectors are verifying right. wouldn't it be neat if we could use tinyusb's mass-storage class to make a usb floppy drive?
