ESP32-C6 is Espressif’s first WiFi 6 SoC integrating 2.4 GHz WiFi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It features an industry-leading RF performance, with reliable security features and multiple memory resources for IoT products. It consists of a high-performance (HP) 32-bit RISC-V processor, which can be clocked up to 160 MHz and a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz. It has a 320KB ROM, a 512KB SRAM, and works with external flash. It comes with 30 (QFN40) or 22 (QFN32) programmable GPIOs, with support for SPI, UART, I2C, I2S, RMT, TWAI, PWM, SDIO, Motor Control PWM. It also packs a 12-bit ADC and a temperature sensor.

The ESP32-C6 has integrated 2.4 GHz WiFi 6 (802.11ax) radio, and also supports the 802.11b/g/n standard for backward compatibility. ESP32-C6 supports the OFDMA mechanism for both uplink and downlink communications, while also supporting MU-MIMO for downlink traffic. Both of these techniques allow working with high efficiency and low latency, even in congested wireless environments. It also combines 2.4 GHz WiFi (802.11 b/g/n/ax), Bluetooth 5 (LE), and IEEE 802.15.4 radio connectivity, which is vital for making the Thread and Zigbee protocols available in a variety of cases of application development.

The ESP32-C6’s support for IEEE 802.15.4 and Wi-Fi radios, along with Bluetooth 5 (LE) connectivity, enable customers to build Matter-compliant Wi-Fi end-point devices and Thread end-point devices, thus achieving interoperability in smart-home devices from multiple brands.

This specific variation of the module features 16MB of flash memory.
