Espressif Systems Releases ESP32-C61 A Wi-Fi 6 and Bluetooth 5 SoC for Superior IoT Performance

Espressif Systems recently launched the ESP32-C61, an advanced System-on-Chip (SoC) with Wi-Fi 6 and Bluetooth 5 (LE). Building on its predecessors like ESP32-C2 and ESP32-C3, it shares similar specifications but adds support for BLE Mesh 1.1 protocol and faster Quad SPI PSRAM, operating at speeds up to 120MHz.

The ESP32-C61, a 32-bit single-core RISC-V microcontroller, operates at 160 MHz and features 320KB of SRAM, 256KB ROM, and compatibility with Quad SPI flash. It also supports Quad SPI PSRAM, providing up to 120MHz speed, which helps developers overcome memory limitations and allows for scalable future developments.

The device supports the latest Wi-Fi 6 standards (802.11ax, 802.11b/g/n) and Bluetooth 5 (LE) for long-range connectivity. It includes advanced features like Target Wake Time (TWT) for power saving in 802.11ax mode, and both OFDMA and MU-MIMO technologies for efficient, high-quality connections with low latency.
