ESP32-H2-MINI-1U is a powerful, generic Bluetooth Low Energy and IEEE 802.15.4 combo module that has a rich set of peripherals. This module is an ideal choice for a wide variety of application scenarios related to Internet of Things (IoT), such as embedded systems, smart home, wearable electronics, etc.

ESP32-H2-MINI-1U comes with a connector for an external antenna and feature a 2 or 4 MB external SPI flash.

ESP32-H2-MINI-1U comes in three versions: 2 MB flash (105C) , 4 MB flash (105C) and 4 MB flash (85C) . These three versions only vary in flash part number and ambient temperature.

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