ESP32-H2-WROOM-03 is a powerful, generic Bluetooth Low Energy and IEEE 802.15.4 combo module thathas a rich set of peripherals. This module is an ideal choice for a wide variety of application scenarios related toInternet of Things (IoT), such as embedded systems, smart home, wearable electronics, etc.

ESP32-H2-WROOM-03 can be vertically soldered to a PCB board via wave soldering. The module has 8 available GPIOs.

At the core of this module is ESP32-H2, a 32-bit RISC-V single-core CPU that operates at up to 96 MHz. Youcan power off the CPU and make use of the low-power coprocessor to constantly monitor the peripherals forchanges or crossing of thresholds.

ESP32-H2 integrates a rich set of peripherals including I2C, I2S, SPI, UART, ADC, LED PWM, ETM, GDMA, PCNT, PARLIO, RMT, TWAI, MCPWM, USB Serial/JTAG, temperature sensor, general-purpose timers, system timer, watchdog timer as well as up to 19 GPIOs
