Luckfox Pico 2 Adopts RP2350A Dual-Core MCU, Launches at $3.99 Luckfox has released the Pico 2 Micro Development Board, a compact module designed around Raspberry Pi’s RP2350A microcontroller. It targets embedded development and experimentation with both ARM and RISC-V instruction sets, offering dual-core support in a low-cost form factor. The RP2350A microcontroller from Raspberry Pi features a dual-core, dual-architecture design, offering both ARM Cortex-M33 and […]

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 🤦 .

On the left is my Pico 2 clone PCB. It has no buttons, the red LED is illuminated. On the bottom edge are 4-pin (I2C) and 3-pin (UART) connectors, both of these have wires to one of my RP2040 Interfacer PCBs which is on the right.

Many people wanted a RESET button on their Pico but I decided to made 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 […]

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.

A small coil of cut tape containing RP2350A0A2 IC.

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 😆 .
