The REES52 ELECROW CrowPi (Upgraded 9-Inch Version) is an industrial-grade, briefcase-style hardware development ecosystem and microcomputer station engineered for comprehensive STEM education, computer science labs, and rapid physical prototyping. Specifically redesigned to natively support the high-performance Raspberry Pi 5 and Raspberry Pi 4B, this all-in-one system houses a premium 9-inch HD IPS capacitive touchscreen alongside an integrated 22+ sensor development matrix within a rugged, deployment-ready protective briefcase. By completely enclosing complex, pre-routed electronic modules into a single, clean workspace with safe GPIO pin breakout hubs, it entirely eliminates breadboard mess and loose jumper wire issues. Supporting effortless software transitions from graphical Scratch blocks to text-based Python, local Artificial Intelligence (AI) deployment, and interactive Minecraft Pi programming, this toolkit stands as a premier B2B solution for school innovation zones, university labs, and Atal Tinkering Labs (ATL).
The central development panel integrates the following 22+ hardware components securely into its circuit fabric without messy external wires:
Core Outputs & Monitors: 9-Inch IPS Multi-Touch Panel, 8$\times$8 Dot Matrix LED Screen, 4-Digit 7-Segment Alphanumeric Display, 16$\times$2 I2C Character LCD Panel, On-board Active Piezo Buzzer, and Status Diagnostic LEDs.
Environmental & Motion Tracking Sensors: DHT20 Digital Temperature & Humidity Sensor, Phototransistor Ambient Light Sensor, PIR Motion Proximity Sensor, Ultrasonic Distance Ranger, Sound Acoustic Audio Sensor, Tilt/Vibration Trigger, and Linear Hall Magnetic Sensor.
Control, Input, & Infrastructure Nodes: Complete 40-Pin GPIO Header Breakout Matrix, Full-Size Mini Breadboard (for custom add-on circuitry), Dynamic 2-Axis Analog Thumb Joystick, 4$\times$4 Tactile Matrix Keypad, Standalone Navigation Push Buttons, Independent 5V Isolation Protection Relay, and an Integrated SPI/I2C Expansion Interface Bus.
Upgraded Raspberry Pi 5 Native Support: Unlike older, restricted setups, this version features a modern Type-C interface board layout and an upgraded cooling fan path. It safely supplies the 5V 5A power needed to prevent under-voltage throttling on the high-speed Raspberry Pi 5 processor core.
The No-Clutter Briefcase Revolution: Groups over 22 common electronic components directly onto a single, solid-state circuit board. This saves hours of layout time and avoids loose connections, incorrect wiring polarities, or broken components during lab experiments.
Built-in 9-Inch Premium Touch Station: Swaps out the small, legacy 7-inch screens for an immersive 9-inch HD IPS display. It provides sharp text views and a smooth capacitive multi-touch interfaceperfect for building local GUI dashboards, editing code, or checking live camera feeds.
Comprehensive AI & Machine Learning Testbed: Supported by over 200+ detailed lessons spanning Scratch, Python, and terminal operations. It includes specialized modules for edge computing, local face detection models, and voice recognition routines using the built-in 2MP camera and microphone.
Q1: Does this kit include the core Raspberry Pi 5 single-board computer, or must it be purchased separately?
A: This kit is available in multiple B2B configurations. The Basic Kit is delivered as an open educational station shell for developers who already own a Raspberry Pi board. The Advanced/Deluxe packages come complete with a Raspberry Pi 5 (4GB/8GB variant) alongside a wireless keyboard, mouse, and gamepads, offering a complete out-of-the-box solution.
Q2: How does the kit switch between using the built-in sensors and building custom external circuits?
A: The board features an onboard hardware master slide switch. Toggling this switch instantly unlinks the pre-routed trace connections to the built-in components, freeing up the full 40-pin GPIO breakout header to interface safely with custom configurations on the built-in breadboard without resource conflicts.
Q3: Can multiple student profiles store their code and learning progress on a single CrowPi device?
A: Yes. The native learning platform software supports offline multi-user account management. This allows students to log into their own personal workspace folders to protect their code files and tracking metrics, making it a highly cost-effective and shareable asset for busy school computer labs.
