ESP32-C6-DevKitM-1 Development Board (4 MB SPI Flash, Zigbee & Thread)

ESP32-C6-DevKitM-1 Development Board is a compact wireless IoT development platform built around the ESP32-C6-MINI-1 module. Powered by a 32‑bit single‑core RISC‑V processor running up to 160 MHz, this ESP32-based development board integrates 320 KB ROM, 512 KB SRAM, and 4 MB SPI flash for embedded applications requiring reliable connectivity and efficient processing. Multi‑protocol wireless capability combines Wi‑Fi 6 (802.11ax), Bluetooth 5 LE, Zigbee 3.0, and Thread 1.3, enabling flexible IoT networking. Breadboard‑friendly pin headers expose most GPIOs, simplifying hardware prototyping and rapid integration into connected electronics, automation systems, and smart sensing projects.

Multi‑Protocol Wireless Connectivity

This IoT wireless controller integrates four major communication technologies in a single module: Wi‑Fi 6 for efficient high‑density wireless networking, Bluetooth 5 LE for low‑energy device communication, and IEEE 802.15.4 support enabling Zigbee 3.0 and Thread 1.3 mesh networking. Such multi‑protocol capability allows seamless development of smart home infrastructure, industrial sensor networks, and interoperable IoT ecosystems. Engineers can experiment with diverse networking stacks using a single hardware platform, simplifying evaluation of emerging IoT standards while reducing hardware complexity during early prototyping stages.

RISC‑V Processing with Low‑Power Co‑Processor

At the core of this compact embedded controller lies a RISC‑V 32‑bit processor capable of operating at up to 160 MHz, supported by 320 KB ROM and 512 KB SRAM. The architecture includes a low‑power co‑processor that can monitor peripherals while the main CPU remains powered down. Such capability enables energy‑efficient sensing and event detection in battery‑powered or always‑on applications. Integrated peripherals and flexible GPIO access further expand possibilities for robotics control, environmental monitoring, and distributed sensing nodes.

Developer‑Friendly Hardware Design

This compact prototyping board exposes nearly all available GPIO pins through standard headers compatible with breadboards and expansion circuits. Two USB interfaces simplify development workflows: a USB‑to‑UART bridge for programming and serial communication, and a native ESP32‑C6 USB Type‑C interface supporting flashing, debugging, and USB protocol communication. An addressable RGB LED connected to GPIO8 provides immediate visual feedback during firmware testing or interactive projects.
