Metro ESP32-S31 Proto’s Out the Door 🚇 We’ve got the Metro ESP32-P4 in the shop, so now it’s time to turn our attention (and routing muscles) to another ESP chip!

high-speed USB, built-in 16M flash and 16M PSRAM on this module, and lots of peripherals, including RGB TTL displays and a camera with a JPEG hardware codec.

It doesn’t have 5 GHz, FYI. This module is going into production soon, so we whipped up a board that lets us quickly prototype projects with Arduino-shield compatibility.

It’s got the classic headers, with high-speed USB on the main USB port, STEMMA QT I2C, reset and boot buttons, a secondary debug USB breakout, DC power, 5V and 3.3V buck converters, SDIO microSD, and a LiPo battery with a charger. 🔧
