PCBBrew

PCBBrew designs real printed circuit boards from a plain-language description: schematic, routed and checked PCB, 3D view, bill of materials, Arduino firmware and an in-browser simulator of the microcontroller.

This connector gives Claude read-only access to PCBBrew's public data and free design checks:

• search_parts: search the catalogue of microcontroller boards (ESP32, Arduino, Raspberry Pi Pico, display boards) and plug-in modules (sensors, displays, motor drivers, radio, storage) by name, chip, use or interface.
• get_part: one board or module with its pins and their role, interfaces, I2C addresses, Arduino libraries and includes, design notes, whether PCBBrew simulates it, a picture and where to buy it; for boards also ADC pins, default I2C/SPI pins, pins to avoid at boot and the logic level.
• check_wiring: checks how modules are wired to a board, pin by pin: missing pins, wrong supply (3.3 V module on 5 V), 5 V signals into 3.3 V GPIOs, analog outputs on non-ADC pins, boot/strapping pins, pins used twice, invalid I2C pins and I2C address conflicts. Works for ESP32, Arduino and Raspberry Pi Pico boards.
• power_budget: typical and peak supply current of a board with its modules (servos, LED strips, displays, radios), compared with what USB and the board's 3.3 V regulator can give.
• search_kicad_parts: search the KiCad symbol libraries PCBBrew designs with (regulators, op-amps, timers, MOSFETs, connectors...), with description and datasheet link.
• list_showcase: boards that PCBBrew users designed and chose to publish.

Useful when planning an electronics project, for example: "I wired a BME280 and an SSD1306 to GP4 and GP7 of a Raspberry Pi Pico: is it right?" or "Can I power two SG90 servos and a 30-LED WS2812 strip from the USB of an ESP32-S3?".

No account and no sign-in are needed. The connector only reads public data; it never accesses private projects or user accounts.
