M5Stack Stamp-C5 – A Tiny ESP32-C5 USB-C board/module with up to 19 GPIO, 3.7V battery support

M5Stack Stamp-C5, also known as the M5Stamp-C5, is a tiny wireless IoT USB-C board based on the Espressif ESP32-C5 RISC-V microcontroller with dual-band WiFi 6, Bluetooth LE, and 802.15.4 (Zigbee/Thread) connectivity. Despite its small size (19.1 x 17.6mm), the module exposes up to nineteen GPIO pins, eleven on standard 2.54mm pitch headers and castellated holes, and eight on an FPC extension header.  The board also supports battery charging and ships with an external IPEX antenna for wireless connectivity, since there’s no built-in antenna.
