Atmega32u4 Beetle

Q: What is a Claude Code skill and how does the Atmega32u4 Beetle skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Atmega32u4 Beetle is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Growth & Marketing category.

Firmware development for the Beetle — the CJMCU / DFRobot "Mini Arduino Leonardo" USB board (ATmega32U4 @ 16 MHz, 5 V, 21×28 mm, castellated pads) — its native USB (CDC serial + HID keyboard/mouse/joystick), Caterina bootloader and 1200 bps touch upload, ten exposed I/O pads, four PWM pins across Timer0/Timer1, five ADC channels, I2C on D2/D3, SPI on the back-side ICSP pads, 28 KB usable flash and 2.5 KB SRAM, and the PlatformIO + Arduino AVR core (`board = leonardo`) setup around them. Use when working on this board or any ATmega32U4 Leonardo/Micro/Pro-Micro-class clone: project setup, platformio.ini, why the board shows up as two different serial ports, uploads that fail or hang, recovering a bricked or HID-spamming board by shorting the ICSP reset pads, pin mapping and which pads are missing, PWM/timer conflicts, Servo and tone, USB HID keyboard projects, the SRAM budget, powering from the + pad, or debugging why something on the board does not work.

From the source SKILL.md

Board-specific firmware knowledge. The Beetle is an ATmega32U4 with native USB and ten pads, and almost every trap on it comes from one of those two facts: USB means the programming interface is the sketch you are about to replace, and ten pads means most of the Leonardo pin numbering the compiler accepts goes nowhere on this board.

What this skill does

Atmega32u4 Beetle is a community-contributed Claude Code skill in the conversion sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/atmega32u4-beetle/ and loads when your prompt matches the skill's trigger.
