Waveshare ESP32-P4-Pico
The Waveshare ESP32-P4-Pico is a compact development board in the Raspberry Pi Pico form factor, built around Espressif's ESP32-P4 SoC. The ESP32-P4 is a high-performance multimedia-focused chip with a RISC-V dual-core processor running at up to 400MHz, plus a low-power core at 40MHz. Unlike other ESP32 variants, the P4 has no built-in WiFi or Bluetooth — it is purpose-built for HMI, video processing, and compute-intensive applications.
Key Highlights
- High Performance: Dual-core RISC-V at 400MHz with AI instruction extensions and single-precision FPU
- Rich Memory: 32MB PSRAM (OPI) + 32MB NOR flash + 768KB on-chip SRAM
- Display and Camera: 2-lane MIPI-DSI for screens up to 10.1 inches and 2-lane MIPI-CSI with integrated ISP for camera modules (OV5647, SC2336)
- Video Processing: Hardware H.264 encoder (1080p at 30fps), JPEG codec, 2D graphics accelerator (PPA)
- Audio System: ES8311 codec + NS4150B Class-D amplifier + onboard MEMS microphone + MX1.25 speaker connector (8 ohm 2W)
- Storage: SDIO 3.0 microSD card slot (up to 40MHz high-speed mode)
- USB: Type-C for power and UART flashing + USB 2.0 OTG High-Speed on 4-pin header
- Expansion: 2x20 pin header with 27 programmable GPIOs, compatible with some Raspberry Pi Pico HATs
Hardware Security
The ESP32-P4 includes comprehensive security features: Secure Boot, Flash Encryption, cryptographic accelerators (AES, SHA, RSA, ECC, ECDSA), True Random Number Generator (TRNG), Digital Signature Peripheral, and Key Management Unit.
