Notes

ESP32-H2-MINI-1U is the variant with external antenna connector (as opposed to ESP32-H2-MINI-1 with PCB on-board antenna).
This pinout is extracted from the ESP32-H2-DevKitM-1 development board documentation, which breaks out the ESP32-H2-MINI-1/1U module pins to header connectors (J1 and J3).
GPIO8 is dedicated to driving the RGB LED on the development board.
GPIO13 and GPIO14 are reserved for the 32.768 kHz crystal (XTAL_32K_P and XTAL_32K_N).
GPIO23 and GPIO24 are used for UART communication (U0RXD and U0TXD).
GPIO26 and GPIO27 are used for USB D- and D+ signals respectively.
For detailed electrical specifications and absolute maximum ratings, refer to the ESP32-H2 Datasheet and ESP32-H2-MINI-1/1U Datasheet.
