ESP32-C3FH4 in ESP32 Family
The ESP32-C3FH4 family, developed by Espressif Systems, represents a cost-effective, single-core RISC-V microcontroller designed to replace traditional ESP8266 modules while adding modern security and connectivity. It integrates 2.4 GHz Wi-Fi and Bluetooth 5 (LE) on a single SoC. These chips are primarily used for secure IoT end-nodes where low power consumption and a small footprint are prioritized over high computational throughput or extensive peripheral sets.
Variants in This Sub-Family
Variants within the ESP32-C3 sub-family primarily differ based on their integrated flash memory capacity and package thermal characteristics. The ESP32-C3FH4 specifically features 4MB of internal flash and is rated for high-temperature environments up to 105 degrees Celsius. Other versions may offer no internal flash, requiring an external SPI chip, or may utilize different pin-out configurations to accommodate specific form-factor requirements in space-constrained PCB designs.
