1 Module Overview
1.2 Description
The series comparison for these two modules are as follows:
Table 1: ESP32-H2-MINI Series Comparison
Both ESP32-H2-MINI-1 and ESP32-H2-MINI-1U come in three versions:
• 2 MB flash (105°C)
• 4 MB flash (105°C)
• 4 MB flash (85°C)
ESP32-H2-MINI-1 and ESP32-H2-MINI-1U are two 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-1 comes with a PCB antenna. ESP32-H2-MINI-1U comes with a connector for an external
antenna. They both feature a 2 or 4 MB external SPI flash.
These three versions only vary in flash part number and ambient temperature. In this datasheet unless otherwise
stated, ESP32-H2-MINI-1 refers to the ESP32-H2-MINI-1 module in 2 MB (105°C), 4 MB (105°C), and 4 MB
(85°C) versions, and ESP32-H2-MINI-1U refers to the ESP32-H2-MINI-1U module in 2 MB (105°C), 4 MB
(105°C), and 4 MB (85°C) versions.
PRELIMINARY
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.
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.
