ESP32-C61HF4
Overview
The ESP32-C61HF4 is a low-power, single-core SoC featuring a 32-bit RISC-V microprocessor running at up to 160 MHz. It integrates 2.4 GHz Wi-Fi 6 (802.11ax) and Bluetooth 5 (LE) connectivity, making it a modern solution for high-efficiency wireless networking. This variant includes 4MB of integrated flash memory and 320kB of SRAM in a compact 5x5mm QFN40 package.
Why Choose This Part
It provides a cost-effective path to Wi-Fi 6 and Bluetooth LE 5.0 integration with a high-performance 160 MHz RISC-V core. The inclusion of 4MB integrated flash reduces PCB footprint, while the hardware-accelerated security features like Secure Boot and Flash Encryption protect firmware integrity.
Applications
Key Specifications
Getting Started
