antigravity-embedded-suite
Agent skill pack for embedded development: pin validation, calibration, and KiCad and SVG schematic output.
What it does and how it connects
The Antigravity Embedded Engineering Suite is an agentic development framework for microcontrollers: ESP32, ESP32-S3, ESP32-C3, Arduino Uno, Nano and Mega, and RP2040. It ships five skills that equip an AI coding assistant with hardware intelligence from schematic design to headless compilation, flashing, sensor calibration and crash triage.
The kicad-schematic skill generates vector SVG schematics and native .kicad_sch files for KiCad 7, 8 and 9, with breadboard hookup tables and electrical safety rules. The embedded-micro skill validates pins before flashing, compiles Arduino C++ and FreeRTOS firmware headlessly with arduino-cli, and flashes over USB serial.
The sensor-calibration skill runs guided experiments with statistical sampling and curve fitting, and the embedded-triage skill decodes crash dumps and probes the I2C bus. A fifth skill, read-telemetry, deduplicates and summarizes serial sensor streams. The skills install by copying them into the Antigravity or Claude Code skills directory.
Alternatives
Compare side by side- AI Embedded Lab
An AI-driven embedded engineering lab where an agent generates firmware, runs it on real hardware or simulation, analyzes results and iterates, rather than a five-skill pack for Antigravity and Claude Code.
- oh-my-embedded
An OpenCode plugin for embedded systems engineering covering ESP32, STM32, FreeRTOS, PCB design and component sourcing, rather than a skill pack for Antigravity.
- Arduino App Lab Agentic Mode
Agentic Mode in Arduino App Lab, where an AI agent works directly on an Arduino project through MCP and App CLI, rather than a standalone skill pack.
- kicad-happy
A suite of agent skills for KiCad that analyze schematics, PCBs and Gerbers, rather than an embedded suite whose KiCad skill only writes schematics.
- freecad-3dprint
An agent skill for designing 3D-printable parts in FreeCAD with a slicer gate, rather than an embedded firmware and schematic skill pack.
Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- Firmware assumed one IS resistor per IBT-2 while the schematic puts two in parallel, so current read about half the real value and a 20 A limit really sat near 40 A; KiCad ERC was clean throughout.Error Index
- phase docs and tutorials named dev boards the project never used, claimed 8 MB flash and 2 MB PSRAM on a 16 MB/8 MB part, put the SPIFFS partition at the wrong offset, and assumed a broker and backend the gateway does not have.Error Index
- The firmware used GPIO 7 for charger detection, which is not broken out on the ESP32-H2-Zero, so it moved to GPIO 10, and the README's divider resistors did not match the schematic's names.Error Index
- Arduino IDE is repeatedly described as lacking standard IDE capabilities and being unsuitable for serious workflows.Error Index
