M5Stack Stamp-AddOn C6 Wi-Fi Expansion Module

M5Stack Stamp-AddOn C6 Wi-Fi Expansion Module is based on the ESP32-C6-MINI-1-N4, designed to extend the wireless communication capabilities of the ESP32-P4 series modules. This module features a 2.4GHz Wi-Fi® 6 wireless protocol, a DC 5V input voltage, and 4MB of flash. The Stamp-AddOn C6 module communicates at high speed with Stamp-P4 via the onboard SDIO interface, quickly expanding high-performance wireless connectivity. This module incorporates development platforms, such as UiFlow2 and Arduino IDE. The Stamp-AddOn C6 module operates over the 0°C to 40°C temperature range in a 138mm x 93mm x 6mm package. Typical applications include smart security gateways, industrial HMI interactive terminals, and complex edge AI nodes.
