The ESP32-P4-Pi-VIEWE is a development board inspired by Raspberry Pi, featuring a VIEWE ESP32-P4C6-Core module. It combines a 400 MHz ESP32-P4 dual-core RISC-V MCU with an ESP32-C6 chip for Wi-Fi 6 and Bluetooth 5.0, along with 32MB PSRAM and 16MB NOR flash. The board supports 10/100Mbps Ethernet, has MIPI DSI and CSI connectors for display or camera, two onboard microphones, a speaker output, a USB 2.0 port, a micro SD card slot, and a 40-pin GPIO header, all in an 85 x 56 mm credit card-sized form.

The ESP32-P4-Pi-VIEWE, known as the ESP32-P4-VIEWE-MD board, maintains similar features to the Waveshare ESP32-P4-Module-DEV-KIT but has two microphones and adds an accelerometer and a gyroscope. It’s available for purchase on AliExpress for $33.13 or on the VIEWE store for $17.99 plus shipping. The board offers support for the ESP-IDF framework, sample code, and schematics available on GitHub.
VIEWE’s board has the same dimensions, hole position, and header pinout as the Raspberry Pi 5. It is more affordable, but Waveshare offers kits with additional accessories like a camera and display.
