Raspberry Pi Pico

Boots real Raspberry Pi Pico (RP2040) firmware on rp2040js — a complete dual-Cortex-M0+ SoC. The default firmware is the official MicroPython build: it brings up a live REPL on the USB-CDC serial console — click the panel and type real Python (try print(2+2) then Enter, or import machine; machine.Pin(25, machine.Pin.OUT).toggle() to flip the on-board LED). The panel shows the on-board LED (GPIO25) and the serial console. Two more firmwares ship in the picker: Blink, a bare-metal program that toggles the on-board LED, and Hello UART, which prints a banner on UART0. Open the debugger to single-step the ARM Cortex-M0+, read/write r0-r15/xPSR, disassemble the XIP flash and boot ROM, set breakpoints and write-watchpoints over the real RP2040 memory map. On-board only — the LED and serial — with no external components, and the bare Pico is naturally silent.
