7-Inch Touchscreen, 16 Integrated Modules, and AI-Ready Development Platform
The Elecrow ESP32-P4 All-in-One Starter Kit is an open-source development platform designed for embedded systems education, rapid prototyping, and edge-AI experimentation. It targets students, academic institutions, and professional developers who require a compact yet capable hardware environment combining AI acceleration, multimedia processing, and rich peripheral integration.
At its core, the kit is powered by the ESP32-P4NRW32 wireless microcontroller. The main processing subsystem consists of a dual-core RISC-V CPU running at up to 400 MHz, featuring AI instruction extensions and a single-precision floating-point unit (FPU).
A dedicated low-power RISC-V core (up to 40 MHz) handles background and energy-sensitive tasks. For graphics and video workloads, the SoC integrates a 2D Pixel Processing Accelerator and a VPU supporting H.264 and JPEG decoding, enabling efficient GUI rendering, camera pipelines, and AI-assisted multimedia applications.
| Component | Specification |
|---|---|
| Main CPU | Dual-core RISC-V, up to 400 MHz, AI instruction extension, single-precision FPU |
| Low-Power CPU | Single-core RISC-V, up to 40 MHz |
| Graphics Accelerator | 2D Pixel Processing Accelerator (GPU) |
| Video Processing | VPU with H.264 and JPEG decoding support |
The kit features a 7-inch IPS capacitive touchscreen with a resolution of 1024 × 600, providing ample screen real estate for LVGL-based GUIs, dashboards, and multimedia interfaces. Visual input is handled by a 2-megapixel wide-angle camera (100° FOV) connected via a MIPI CSI interface, suitable for computer vision, image capture, and basic video processing tasks.
Sixteen onboard electronic modules are pre-integrated, eliminating the need for external wiring during early development stages. These modules cover a broad range of sensing, actuation, and user-interaction scenarios.
| Category | Integrated Modules |
|---|---|
| Sensors | PIR motion sensor, accelerometer & gyroscope, ultrasonic distance sensor, DHT22 temperature & humidity sensor, MQ-2 gas sensor, Hall sensor, ambient light sensor, capacitive touch sensor |
| Actuators & I/O | Relay module, servo motor interface, speaker, microphone, user buttons, LEDs |
The memory subsystem is designed to support multitasking, GUI frameworks, and AI inference workloads. On-chip SRAM is complemented by external PSRAM and NOR Flash, while expandable storage is available via MicroSD.
| Memory Type | Capacity |
|---|---|
| HP L2MEM | 768 KB |
| LP SRAM | 32 KB |
| TCM | 8 KB |
| HP ROM | 128 KB |
| LP ROM | 16 KB |
| External PSRAM | 32 MB |
| External NOR Flash | 16 MB |
| Expandable Storage | MicroSD card slot (SDIO 3.0) |
The ESP32-P4 All-in-One Kit provides a wide selection of wired and expansion interfaces, enabling integration into both standalone and networked embedded systems.
| Interface | Details |
|---|---|
| Ethernet | 100 Mbps RJ45 with PoE support |
| USB | 2 × USB Type-C (power and data), 1 × USB Type-A |
| Wireless Expansion | Dedicated module slot for optional wireless add-ons |
| Debug & Serial | JST connectors for UART and I²C |
| Expansion Headers | 2 × 20-pin headers (GPIO, I²C, UART, 5 V, 3.3 V, GND) |
Development is centered around Espressif’s ESP-IDF framework, with C and C++ as the primary programming languages. Elecrow provides step-by-step documentation for configuring Visual Studio Code with ESP-IDF and Python tooling. Support for the Arduino IDE is planned through upcoming factory firmware releases.
The official GitHub repository includes open-source schematics, example projects, and more than 20 structured tutorials, covering topics such as:
- Digital and analog I/O
- Audio input/output processing
- LVGL-based GUI development
- Sensor interfacing
- Camera integration and image pipelines
- Voice processing fundamentals
- Introductory edge-AI workloads
These resources allow learners to progress systematically from basic embedded concepts to multimedia and AI-assisted applications.
Compared to Elecrow’s earlier educational kits—such as Raspberry Pi Pico-based solutions and the CrowPi series—this ESP32-P4 platform is explicitly optimized for embedded AI, computer vision, and voice interaction. It fills a practical gap for developers preparing for edge-AI and intelligent device deployments, rather than general-purpose programming alone.
The entire system is housed in a portable, suitcase-style PP plastic enclosure, measuring 195 × 170 × 46 mm and weighing approximately 600 g. Power is supplied via 5 V USB Type-C, making the kit suitable for desktop use, classrooms, and mobile demonstrations.
