The ESP32-P4-Pi-VIEWE is a Raspberry Pi-inspired development board equipped with a VIEWE ESP32-P4C6-Core module, combining a 400 MHz ESP32-P4 dual-core RISC-V MCU with an ESP32-C6 chip for Wi-Fi 6 and Bluetooth 5.0 wireless connectivity, as well as 32MB PSRAM and 16MB NOR flash.
The board also offers 10/100Mbps Ethernet connectivity, MIPI DSI, and CSI connectors for display and/or camera, two onboard microphones, a speaker output, a USB 2.0 port, a micro SD card slot, and the usual 40-pin GPIO header, all in a familiar 85 x 56 mm credit card form factor.

VIEWE provides instructions to get started with the ESP-IDF framework and some sample code for audio, Ethernet, camera, display (LVGL), and the usual ESP-Brookesia demo, as well as the PDF schematics on GitHub.
If this type of ESP32-P4 + ESP32-C6 credit card-sized board feels familiar, it shares many of the same features as the Waveshare ESP32-P4-Module-DEV-KIT we covered in April 2025. The main differences are that the Waveshare board comes with four USB Type-A ports, and the VIEWE board integrates two microphones instead of one, and also adds an accelerometer and a gyroscope.
Both are also based on a single module combining an ESP32-P4 with 32MB PSRAM, an ESP32-C6, and 16MB flash. Even the IPEX connector is in the same position.
VIEWE usually offers a slightly lower price point, and the ESP32-P4 Pi VIEWE can be purchased for $33.13 on AliExpress, including shipping, or on the VIEWE store for $17.99 plus shipping. One advantage of the Waveshare model is that it’s also offered in kits with a camera, a display, and other accessories, and it’s less obvious how to do that with the VIEWE model.
