ESP32-H2-WROOM-03 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-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. 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 Features CPU and On-Chip Memory ESP32-H2 embedded, RISC-V single-core 32-bit LX7 microprocessor, up to 96 MHz 128 KB ROM 320 KB SRAM 4 KB LP Memory 2 MB or 4 MB in-package flash Bluetooth Bluetooth Low Energy (Bluetooth 5.3 certified) Bluetooth mesh Bluetooth Low Energy long range (Coded PHY, 125 Kbps and 500 Kbps) Bluetooth Low Energy high speed (2 Mbps) Bluetooth Low Energy advertising extensions and multiple advertising sets Simultaneous Broadcaster, Observer, Peripheral and Central Multiple connections LE power control IEEE 802.15.4 IEEE Standard 802.15.4-2015 compliant Supports 250 Kbps data rate in 2.4 GHz band and OQPSK PHY Supports Thread 1.3 Supports Zigbee 3.0 Supports Matter Supports other application-layer protocols (HomeKit, MQTT, etc) Peripherals GPIO, I2C, I2S, SPI, UART, ADC, LED PWM, ETM, GDMA, PCNT, PARLIO, RMT, TWAI®,MCPWM, USB Serial/JTAG, temperature sensor, general-purpose timers, system timer, information about the module peripherals.
