- boot_images manifest: bump arm64 rootfs (gpiozero/colorzero baked in,
hostname applied at boot, reworded MOTD)
- RaspberryPi3Bridge: onBooted shell-ready detector + sendAndWaitForPrompt
flow control (resets on disconnect)
- RaspberryPiWorkspace: distinct Booting overlay + piBooted-driven status,
inline SVG icons replacing emoji glyphs
- SerialMonitor: strip CSI/DSR escapes so the dumb console no longer shows
a literal [6n next to the prompt
- VirtualFileSystem: upload auto-starts the Pi and waits for the shell, then
flow-controls each command (no more dropped lines on large files)
- i18n: bootingTitle/bootingNote + reworded offlineNote2 across 9 locales
- ESP32 / Raspberry Pi / STM32 / Pico-W bridges built their WebSocket URL
from a bespoke API_BASE() that read only VITE_API_BASE (fallback
localhost:8001) and ignored the desktop shell's runtime-injected
window.__VELXIO_API_BASE__. On the desktop the sidecar runs on a random
127.0.0.1 port, so the sim WebSocket dialed localhost:8001 and never
connected: compile succeeded but the simulation never started. Honor
__VELXIO_API_BASE__ first; web (/api) and dev (localhost:8001) unchanged.
- nano-button-led example: button was wired D2->1a and 1b->GND (same
terminal), tying D2 to GND permanently. Rewire D2->1.l and GND->2.l
(opposite terminals), matching the other examples.

Adds the public extension points the velxio-prod overlay uses to bind
real canvas-side I2C/SPI/UART models (BME280, future MCP23017, etc.)
to a running Pi guest's protocol shims:
- qemu_manager: set_pi_slave_handler(fn) / get_pi_slave_handler() for
pi_attach_slave + pi_detach_slave WebSocket messages. OSS image
leaves the hook unset so the messages are silently dropped.
- simulation route: parses the two new WS message types and forwards
them to the registered handler when present.
- RaspberryPi3Bridge: attachSlave(spec) / detachSlave(spec) frontend
side of the protocol.
- piSlaveScanner: at simulation start walks components + wires,
identifies I2C/SPI/UART peers wired to Pi protocol pins (40-pin
header physical-pin numbering), and emits one attach per
bus/address pair (deduped across SDA+SCL wires).
- RaspberryPiWorkspace: invokes the scanner once the bridge is open,
with retries to ride out the WS-still-connecting race.
- integration test: pi3_bme280_attach.py boots the Pi, pre-attaches a
BME280 via the slave handler, runs a host-side proto loop, runs
guest python smbus2.read_byte_data(0x76, 0xD0) and asserts the
console reads back CHIP=0x60.

Backend: extract per-board config into a PI_CONFIGS dict keyed by
board_type. Pi 3/4/5 share the same arm64 image set (kernel +
initramfs + rootfs) and differ only in QEMU -cpu and -m:
raspberry-pi-3 → cortex-a53 + 1G (BCM2837, ARMv8 64-bit)
raspberry-pi-4 → cortex-a72 + 2G (BCM2711, ARMv8 64-bit)
raspberry-pi-5 → cortex-a76 + 2G (BCM2712, ARMv8 64-bit)
PiInstance now carries board_type so the per-board lookup happens
once at start_instance time. Unknown board_type falls back to
DEFAULT_PI_BOARD ('raspberry-pi-3') instead of erroring out (for
back-compat with older clients).
Pre-warm hook walks every unique image_set in PI_CONFIGS so the
provider only downloads each set once even when several Pi models
are registered.
Frontend:
- BoardKind union gains 'raspberry-pi-4' and 'raspberry-pi-5'.
- BOARD_KIND_LABELS + BOARD_KIND_FQBN entries for both new boards
(FQBN null since they use the Pi VFS + Python toolchain like Pi 3).
- ComponentRegistry inserts two new component metadata entries
cloning the Pi 3 board art with different thumbnail colours.
Tag name reused so the same velxio-raspberry-pi-3 web element
draws the board on the canvas — the 40-pin GPIO layout is
identical across Pi 3/4/5.
- boardProtocols.ts: Pi 3/4/5 share the BCM physical→GPIO table
(PI3_BCM) since the 40-pin header layout is identical.
- loadExample.ts: where 'raspberry-pi-3' is special-cased (VFS
ingest, .cpp vs .ino filename), now matches Pi 3/4/5 alike.
- Interconnect.isPi3Bridge() recognises all three Pi family members
so Arduino↔Pi serial routing keeps working.
- RaspberryPi3Bridge constructor gained a boardKind parameter
defaulting to 'raspberry-pi-3'. The WebSocket 'start_pi' message
now ships the actual board kind so the backend knows which
PI_CONFIGS entry to use.
- useSimulatorStore.addBoard wires bridge construction for all
three Pi family members.
Pi Zero/Pi 1/Pi 2 (armhf) come in Phase 3.3 — separate kernel
package + armhf rootfs build, no change here.
Smoke-tested inside the prod container:
Pi 4 (cortex-a72) → reached agetty login on hvc0
Pi 5 (cortex-a76) → reached agetty login on hvc0
Both show 'aarch64' in uname -m.

- Changed JSX declarations to use 'velxio-' prefix for various components.
- Updated component overrides to replace 'wokwi-' with 'velxio-' for logic gates and other components.
- Adjusted SVG generation script to use 'velxio-' prefix for BMP280 and Raspberry Pi components.
- Marked submodules as dirty in QEMU and RP2040 libraries.
- Added .prettierignore and .prettierrc.json for consistent code formatting.
- Introduced InstrumentComponent with support for Voltmeter and Ammeter, including pin information handling.
- Introduced new BoardKind types for Raspberry Pi 3B and updated BoardInstance interface.
