ALIENTEK DNESP32P4M – An ESP32-P4 board without network connectivity

Most ESP32-P4 boards and development platforms we’ve covered so far include an ESP32-C6 or ESP32-C5 wireless module, and in case you don’t want any WiFi and Bluetooth module, the Olimex ESP32-P4-DevKit is one option that comes with Ethernet instead.

The ALIENTEK DNESP32P4M board, also called ESP32P4M MINI, adds another option with a form factor similar to Espressif Systems Devkit-C boards. The board does not have network connectivity at all, and exposes all I/Os from the ESP32-P4 through headers, MIPI DSI and MIPI CSI connectors, and two USB-C ports.

ALIENTEK DNESP32P4M specifications:

• Microcontroller – ESP32-P4 (ESP32-P4NRW32)
  • MCU
    • Dual-core RISC-V microcontroller @ 400 MHz with AI instructions extension and single-precision FPU
    • Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz
  • GPU – 2D Pixel Processing Accelerator (PPA)
  • VPU – H.264 and JPEG codecs support
  • Memory – 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM, 32MB PSRAM
  • Storage – 128 KB HP ROM, 16 KB LP ROM
• Storage
  • 16MB SPI NOR flash
  • MicroSD card slot
• Display interface – 2-lane MIPI DSI connector supporting 5.5-inch and 10.1-inch MIPI screens from “Zhengdian Atom”.
• Camera interface – 2-lane MIPI CSI connector
• USB
  • USB UART Type-C port
  • USB data/JTAG Type-C port
• Expansion 2x 25-pin headers for up to 48x GPIO
• Misc
  • Power and user LEDs
  • BOOT and RESET buttons
  • Serial port configuration jumpers
• Power Supply – 5V via USB-C port
• Dimensions – 68 x 33 mm (4-layer PCB)

There’s no information about software support, except that we’re told the ESP-IDF framework and the Arduino IDE are supported. It should be possible to select ESP32P4 Dev Module in the Arduino IDE, like I did with the M5Stack Tab5 devkit.

The bottom side of the board shows that the “DNESP32P4M V1.0” board is made by ALIENTEK, but when I go to the English version of the website, the MCU board section is empty. However, the Chinese version has more details about the board itself, the ATK_DNESP32P4M baseboard, and a long list of demo programs for the ESP-IDF, LVGL, Arduino, FreeRTOS, and so on. Sadly, the download (下载 ) section is empty right now. The page “http://www.openedv.com/docs/boards/esp32/ATK-DNESP32P4.html” is supposed to have more information, but the website is not loading at all for me.

The ESP32P4 MINI / DNESP32P4M board can be purchased on AliExpress for $19.24. The ATK_DNESP32P4M baseboard shown below is not for sale on AliExpress.
