Luckfox Pico 2 Adopts RP2350A Dual-Core MCU, Launches at $3.99

@rpimag I did a bit more work on my UART booting Flashless Picos. On the end of each "pico" there's an I2C port for the I/O expander (used to reset/setup the RP2350A to boot from UART) and a UART port to send the bin file/communicate after boot. The Pico2 in the PicoUART6 is running CircuitPython using Adafruit_CircuitPython_PIO_UART for the non-hardware UARTs.

Glad I'd left plenty of space around the #RP2350A on my latest #JLCPCB #PCBA order as they'd been a bit tight with the solder and I had to run an iron down one side to get it working 🤦 .

Many people wanted a RESET button on their Pico but I decided to make one without buttons 🤣 .

It currently has no FLASH/PSRAM and boots over UART (3-pin at the bottom) or you can upload a UF2 over USB. The I2C expander towards the bottom (4-pin STEMMA QT) can twiddle the BOOTSEL, SD1 and RUN pins.

I've hacked together a CircuitPython library to UART boot the RP2350. The two bin files it's uploading just cycle through the LEDs in different directions.

I still have no RUN pin so I'm using one of my USB Power Switches to power cycle the board.

The RP2350A is feeling a bit more real today as I have cut tape in my hands (from #LCSC). Now I just need to find the board I designed for them back in September 😆 .
