Another day, another ESP32-P4 RISC-V MCU board with the ESP32-P4-MINI equipped with an ESP32-C6 wireless module and exposing all I/Os through two 34-pin GPIO headers.
The board also features two USB-C ports, one for data and one for debugging, MIPI DSI and MIPI CSI connectors to add a display and a camera, a microSD card slot for storage, and a few buttons and LEDs. It’s basically a board for engineers wanting to access all features of the ESP32-P4 without extra bells and whistles.

There’s limited information about software support, and people are just told to the the ESP-IDF framework with Visual Studio Code. The schematics are shared on the AliExpress page (see below) includng the pinout for the GPIO headers.
The ESP32-P4-MINI board can be purchased for $20.80 plus shipping and taxes on AliExpress. I was unable to find a product page for the board, but the schematics on the AliExpress page imply “Kevincoooool” may have developed the board.
