+=====ESP32-H2=====
+==ESP32-H2 General Information==
+ESP32-H2 is a family of microcontrollers (SoC) that combines IEEE 802.15.4 connectivity with Bluetooth 5 (LE). The system does not have a Wi-Fi protocol, but Thread and Zigbee protocols are available. ESP32-H2 has been certified as a “Zigbee-Compliant Platform” and has officially become a “Thread-Certified 1.3.0 Component”. The SoC is powered by a single-core, 32-bit RISC-V microcontroller that can be clocked up to 96 MHz. The ESP32-H2 has been designed especially for connected devices with low power consumption and security in mind. ESP32-H2 has 320 KB of SRAM with 16 KB of Cache, 128 KB of ROM, 4 KB LP of memory, and a built-in 2 MB or 4 MB SiP flash. It has 19 programmable GPIOs supporting ADC, SPI, UART, I2C, I2S, RMT, GDMA and LED PWM.
+For now, the ESP32-H2 family documentation is available as preliminary information only.
+== ESP32-H2 Architecture Overview ==
+Figure {{ref>esp32h2_functions}} shows a functional block diagram of the ESP32-H2 chip. Main common features of the ESP32-H2 are ((https://www.espressif.com/sites/default/files/documentation/esp32-h2_datasheet_en.pdf)):
