Vendors the fork's 11 granular UNO Q skills (bridge, flashing, led-matrix, uno-q-hardware, sketch-patterns, modulino, linux-led, audio, vision, wireless, arduino-app-lab) next to the comprehensive arduino-uno-q skill, and installs the whole set into every agent's workspace on each board. Why both: the comprehensive skill is the rich cloud reference (read_skill → references); the granular skills are keyword-triggered and match the fork's eager skill-inliner rules, so the on-board Qwen auto-inlines them (no read_skill round-trip). flashing + led-matrix carry the exact uno_q_flash + frame-API / ArduinoGraphics-not-installed detail that makes flashing reliable. - push-skill.sh generalized: a single skill dir (has SKILL.md) OR a parent dir installs every skill under it; provision-fleet now ships all of skills/. - Verified on board 65301572: cloud/Sonnet-5 lists all 12 skills.

| uno-q-hardware | Arduino Uno Q board pinout and voltage rules — PWM pins, 3.3V ADC limits, I2C/SPI/Serial pins, and the MPU vs MCU split. Load this before answering any question that names a pin (D0-D21, A0-A5) or a voltage, or before writing a sketch that uses analogRead/analogWrite/Wire/SPI/Serial. |
Arduino Uno Q Hardware
Two processors talk over an RPC Bridge:
- MPU (Linux) — Qualcomm QRB2210, 4× Cortex-A53. Runs ZeroClaw, the LLM, arduino-cli, OpenOCD. MPU I/O is 1.8 V and is not reachable from sketches.
- MCU (Arduino) — STM32U585, Cortex-M33, Zephyr + Arduino core. Runs
.inosketches. Every Arduino header (JDIGITAL, JANALOG, JSPI, Qwiic) is 3.3 V.
Sketches always target the MCU (arduino:zephyr:unoq).
Quick facts
- PWM pins: D3, D5, D6, D9, D10, D11 (the
~pins).analogWriteonly works here. - Built-in LED: D13.
- I2C2 (
Wire): SDA = D20, SCL = D21. I2C3 (Wire1): SDA = A4, SCL = A5. I2C4 = the Qwiic connector (plug-and-play Modulino sensors). - SPI (SPI2): D10 = CS, D11 = MOSI, D12 = MISO, D13 = SCK.
- Serial:
Serial= D0 (RX), D1 (TX). - DAC: A0 = DAC0, A1 = DAC1 (12-bit;
analogWriteResolution(12)). - CAN: FDCAN1 on D4 (TX), D5 (RX) — needs a transceiver (e.g. TJA1051T/3).
Voltage safety — call this out every time
- ADC inputs A0–A5 accept 0–3.3 V only (abs max ~3.6 V). 5 V on A0–A5 damages the STM32U585. Unlike a classic 5 V Uno.
analogRead()returns 0–1023; volts =raw * 3.3 / 1023.0.- For a 5 V sensor, divide down: 5 V → 10 kΩ → A0 → 20 kΩ → GND.
On-board LEDs
- RGB LED 1/2 are MPU-owned (
/sys/class/leds/*, use thesysfs_ledtool). - RGB LED 3/4 are MCU-owned (
analogWrite/digitalWritein a sketch). - All RGB LEDs are active-low (write 0 = on).
sysfs_ledinverts this for you.
