rp2350a-weact SKILL.md skillA

rp2350a-weact from alexex1993/mcu-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add alexex1993/mcu-skills/rp2350a-weact@git:20261030.816967f

Pins git:20261030.816967f in mdr.lock. Pin the fingerprint instead.

Firmware development for the WeAct Studio RP2350A Core Board (RP2350A — dual Cortex-M33 @ 150 MHz, 520 KB SRAM, 4 MB or 16 MB QSPI flash) in both of its revisions, RP2350A_V10 and RP2350A_V20 — the 40-pin Pico-2-shaped header, 3-or-4-channel 12-bit ADC, PWM, PIO, USB-C CDC, the V1.0 LDO vs V2.0 buck-boost power wiring, and the PlatformIO + arduino-pico (earlephilhower) setup around them. Use when working on this board, a WeAct RP2350 core board of unknown revision, or any Raspberry Pi Pico 2 /…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# WeAct Studio RP2350A Core Board (RP2350A)

A Pico-2-shaped RP2350A core board that ships in **two incompatible
revisions under one name**. V2.0 is a pin-for-pin Pico 2 replacement; V1.0
brings out every GPIO instead, and pays for it by moving the power pin, the
ADC reference and three GPIO functions. Firmware built for the wrong one
compiles cleanly and then drives the wrong pins — so establish the revision
before writing any code, and read the reference files rather than assuming
Pico 2 behaviour.

- `reference/board-hardware.md` — the complete board reference: how to tell
  the revisions apart, the 40-pin map for both, the off-header GPIO, power
  trees, clocks, memory map, vendor-material inventory **plus** a development
  guide (Part II: §8 toolchain, §10 peripheral cookbook, §11 RP2350 gotchas
  including erratum E9 and the PWM slice map, §12 flashing, §13 a
  symptom → cause → fix table).
- `reference/recipes.md` — copy-paste code: `platformio.ini` with all four
  envs, the revision guard, reading the real flash size out of the chip,
  LEDs, the KEY button, V2.0 power sensing, ADC, `Wire1` remapping, PWM,
  EEPROM, LittleFS, core 1.

How to install

The exact contents, by fingerprint

mdr add alexex1993/mcu-skills/rp2350a-weact@sha256:59f9ee7bd5f984b9

The line at the top of this page pins the label git:20261030.816967f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
