The Waveshare ESP32-P4-Nano is a tiny, inexpensive, low-power development board powered by a dual-core RISC-V processor. Available now from Waveshare or AliExpress for around $19 and up, the little board packs a lot of connectivity into a compact design.

Waveshare's board measures just 50 x 50mm (about 2″ x 2″) but it has a 10/100 Ethernet port, USB Type-C and Type-A ports, and support for WiFi 6 and Bluetooth 5.

At the heart of the device is an ESP32-P4 microcontroller that features a two 32-bit RISC-V CPU cores running at up to 400 MHz with a single low-power RISC-V MCU core that tops out at 40 MHz. It also features 32MB of PSRAM, 16MB of onboard Nor flash storage, and support for H.264 video encoding, JPEG image processing, and voice processing, among other things.

While the ESP32-P4 itself doesn't support WiFi and Bluetooth, there's also an ESP32-C6-Mini-1 chip that handles those features.

Ports and connectors include:

  • 1 x 10/100 Ethernet (with PoE module header)
  • 1 x USB 2.0 Type-A
  • 1 x USB Type-C (for power and data)
  • 1 x microSD card reader (SDIO 3.0)
  • 1 x 2-lane MIPI-DSI display connectors
  • 1 x 2-lane MIPI-CSI camera connector
  • 1 x onboard mcirophone
  • 1 x 2-pin speaker header
  • 2 x 26-pin GPIO headers
  • 1 x RTC battery header

    • The $19 starting price includes the board and a small speaker. But Waveshare also offers kits that bundle the board with add-ons such as a 5MP Raspberry Pi camera, Power over Ethernet (PoE) module, and a 10.1 inch, 1280 x 800 pixel capacitive touchscreen IPS LCD display.
