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 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. The main differences are that the Waveshare board comes with four USB Type-A ports, while the VIEWE board integrates two microphones instead of one, and also adds an accelerometer and a gyroscope. Both are based on a single module combining an ESP32-P4 with 32MB PSRAM, an ESP32-C6, and 16MB flash.
The ESP32-P4 PI-VIEWE keeps the same dimensions, hole position, and header pinout as the Raspberry Pi 5, making it compatible with many existing enclosures and accessories.
The ESP32-P4 Pi VIEWE can be purchased for $33.13 on AliExpress, or on the VIEWE store for $17.99 plus shipping.
