ESP32-C61-WROOM-1U-N8R8 Wireless Communication Module Wi-Fi 6 + BLE Dual Mode Wireless Module
ESP32-C61-WROOM-1U-N8R8 is a 2.4GHz Wi-Fi 6 + BT 5 (LE) dual-mode wireless module based on the ESP32-C61 SoC. Designed for low-power, cost-effective Internet of Things (IoT) applications, it features 8MB of Flash and 8MB of PSRAM, and utilizes an external antenna (U.FL) interface.
The module is based on a 32-bit single-core RISC-V processor (RV32IMAC) with a maximum clock speed of 160MHz. It integrates 2.4GHz Wi-Fi 6 (802.11ax) and Bluetooth 5 (LE) dual-mode wireless capabilities, supporting Wi-Fi 6 features such as OFDMA, MU-MIMO and Target Wake Time (TWT), optimizing concurrent operation of high-density IoT devices and low-power standby.
