ESP32-C61HR2
Overview
The ESP32-C61HR2 is a cost-effective, low-power System-on-a-Chip (SoC) that integrates a 160 MHz RISC-V single-core processor with 2.4 GHz Wi-Fi 6 and Bluetooth 5 (LE). It is designed to provide modern wireless connectivity for IoT devices, featuring 320kB of SRAM and 256kB of ROM in a compact 5x5 mm QFN40 package.
Why Choose This Part
This SoC introduces Wi-Fi 6 (802.11ax) support to the ESP32-C series, offering better performance in congested wireless environments. The RISC-V architecture provides a modern, royalty-free core with standard extensions like PMP and PMA for enhanced security and memory protection.
Applications
Key Specifications
Getting Started
Developers can use the Espressif IoT Development Framework (ESP-IDF) which provides comprehensive drivers and libraries for the RISC-V core and wireless stacks. Hardware prototyping is best performed with ESP32-C61 series development kits using a standard USB-to-UART bridge for flashing and debugging.
Dev Boards
Development boards and breakout modules featuring the ESP32-C61HR2 or compatible chips — ready to use for prototyping.
