ESP32-H2FH2

RF Transceiver ICS Overview

The ESP32-H2FH2 is a low-power single-core 32-bit RISC-V System-on-Chip (SoC) by Espressif Systems, integrating IEEE 802.15.4 and Bluetooth 5 (LE) for secure wireless connectivity. It features 2 MB of internal flash memory, 320 kB SRAM, and 128 kB ROM. The device operates on a 3V to 3.6V supply voltage with a maximum transmission power of 20 dBm and a sensitivity of -106.5 dBm. It supports data rates up to 5 Mbps using O-QPSK modulation in the 2.4 GHz frequency band. The chip includes 19 GPIOs and interfaces such as SPI, I2C, UART, and USB. It is housed in a 32-VFQFN package with exposed pad and functions within a temperature range of -40°C to 105°C.
