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.
