M5StampC5 Module (ESP32-C5)

The Stamp-C5 is a compact ESP32-C5 wireless module with dual-band Wi-Fi 6, Bluetooth LE, Zigbee and Thread connectivity for connected IoT and embedded projects.

The M5Stack Stamp-C5 is a highly integrated wireless connectivity module based on the Espressif ESP32-C5HF4, designed for IoT applications that require efficient and stable communication.

It supports 2.4 & 5 GHz dual-band Wi-Fi 6, BLE 5, and IEEE 802.15.4 (Zigbee, Thread) multi-protocol connectivity, meeting device access requirements across different network scenarios.

The module uses a RISC-V 32-bit single-core processor with a clock frequency of up to 240MHz, includes 4MB Flash, and integrates hardware resources such as USB Type-C, a battery power input, an FPC expansion interface, and an IPEX-1 antenna connector.

The module adopts a 2.54mm pad pitch design, making it easy to quickly connect various peripherals and expand functions. While ensuring connectivity performance and security, it helps developers complete prototype validation and product implementation more efficiently.
