Espressif’s ESP32-C5 Features a Dual-Band Wi-Fi 6 Radio with MU-MIMO, TWT, and More

Espressif Systems has recently introduced the ESP32-C5 a MCU with dual-band (2.4 & 5.0 GHz) WiFi-6 and Bluetooth 5.0 LE support.

Previously we have seen Espressif release many MCU such as the ESP32-C6, and ESP32-C61, both of which are capable of handling 2.4GHz radio connectivity, but this is the first module from Espressif that will support both the 2.4 & 5.0 GHz radio.

Support for 5 GHz Wi-Fi on the ESP32-C5 enhances IoT devices with OFDMA and MU-MIMO for efficient, low-latency connectivity in crowded settings, and there will also be support for TWT which will add to extended battery life. This MCU can support 5G speeds so this setup will enable applications like live streaming, Wi–Fi dongles, and IP cameras. Espressif ensures software continuity with the ESP-IDF, supporting both ESP32 and ESP8266 devices, and offers options for using ESP32–C5 as a co-processor via ESP-AT or ESp-hosted SDKs.
