ESP32-P4-MINI development board exposes all I/Os with dual 34-pin headers, supports WiFi 6 with ESP32-C6

The ESP32-P4-MINI is a compact development board designed for engineers and developers to explore the full capabilities of the ESP32-P4 RISC-V microcontroller.  What’s unique about this board is that it exposes all 34-pin GPIO headers, offering access to all I/Os.

In addition to full GPIO access, the ESP32-P4-MINI integrates a dedicated ESP32-C6-MINI-1-N4 wireless module supporting Wi-Fi 6, Bluetooth 5.x LE, and 802.15.4 for Zigbee, Thread, and Matter, making it suitable for a wide range of IoT protocols. Additionally, it features 16MB NOR flash, 32MB PSRAM, a microSD card slot, a 2D GPU, H.264/JPEG video codec support, secure boot and flash encryption, and buttons and LEDs for user interaction. It is powered via a 5V USB-C input. While software support is currently limited, it is compatible with the ESP-IDF framework via Visual Studio Code, making it suitable for developing multimedia, IoT, or AI-edge applications.

The ESP32-P4-MINI development board currently has limited software support but is compatible with the ESP-IDF (Espressif IoT Development Framework), which can be used through Visual Studio Code for application development. While official SDKs are still evolving, developers can leverage the ESP-IDF ecosystem to access key features such as Wi-Fi 6, Bluetooth LE, and 802.15.4 protocols. But while searching GitHub, I found some example code which indicates support for MIPI CSI camera input and H.264 video encoding to microSD storage.

The ESP32-P4-MINI is available on AliExpress for about $20.80 plus shipping. Although there’s no official product page, the schematics suggest it was made by “Kevincoooool.”
