I keep needing the same thing - a really basic dev board for whatever Espressif module I’m playing with. USB-C, a 3.3V regulator, BOOT and EN buttons, three LEDs (5V present, 3.3V present, and one on a GPIO so you can run the blink sketch), and every GPIO broken out on headers. Nothing clever, just the minimum board that gets a bare module doing something. While building the ESP32 module database I noticed there are twelve modules that fit one sensible recipe - a PCB antenna and native USB - spread across the S2, S3, C3, C5, C6 and H2 families. Native USB is the bit that keeps the component count down. There’s no USB to UART bridge to buy and route, just a USB-C socket and a couple of 5.1K resistors on the CC pins so the host actually hands over power. Twelve near-identical boards is exactly the kind of job that makes you question your life choices in KiCad. So I did what everyone on the internet is currently telling you to do and asked Claude to spin up a team of AI agents to design…
