Elecrow’s latest invention, the CrowPi3, is an all-in-one Raspberry Pi 5 platform that bundles many popular Arduino modules in a book-sized suitcase. A 4.3” LCD sits in the center with a camera on top. Modules usually used to introduce electronics, such as a breadboard or an LED matrix, are also included. They are all connected to the Pi through its 40-pin header connector. The unit has a built-in battery pack that should provide hours of fun.
Elecrow is running a Kickstarter campaign that will end on July 5th. The product’s main selling point is that it can be used as a hardware enabler for AI designs. How much this is true depends on the software ecosystem that ships with it. Elecrow is smart by using the Raspberry Pi as part of its design. This opens thousands of AI and ML libraries for the younger generation targeted by this product.
CrowPi3: Price and Availability
The CrowPi3 is available in nine configurations on the Kickstarter webpage. The Early Birds offer the most value for money and start at $159 for the basic kit, excluding the Pi computer. An 8GB Pi 5 with battery and a gamepad will add an extra $130.
CrowPi3: Design
The CrowPi3 ships with a transparent plastic cover on the main experiment board, which helps protect the delicate circuits and LCD module while on the go.
Specification
Supported board: Raspberry Pi 5, Pi Pico, Arduino, Micro: bit
Number of extensions: 28 Arduino-compatible modules
Size: 28.5 cm x 18.5 cm x 3.8 cm
Weight: 1.1 kg
Video: 4.3” 800 x 480 IPS LCD, 1 x HDMI
Audio: Stereo speaker, 3.5mm headphone jack
Power supply: 27W 12V power adapter
Two small magnets hold the cover in place while a rubber strap on top acts as a handle, creating a look similar to a suitcase. The unit measures 28.5 cm x 18.5 cm x 3.8 cm, for a weight of 1.1 kg, and feels solid. The two compartments on the bottom are easily accessible by sliding plastic doors. One holds the Raspberry Pi board, while the other can store small parts.
Elecrow went above and beyond to pack over thirty electronic modules in a small volume. Even more impressive is that they are all connected to the Pi expansion connector. If the Pi is too much of a hassle to work with, then two extra sockets accommodate a Raspberry Pi Pico board or an Arduino, while the breadboard space allows adding other modules easily.
The Raspberry Pi 5 provides over twice the processing power of its predecessor. The CrowPi3 utilizes all of the Pi’s connectors and interfaces; Two HDMI connectors connect to the integrated display and an optional external screen. The user can access only three USB 3 ports, the fourth reserved for the two-megapixel camera. A 4.3-inch 800 x 480 IPS screen offers excellent brightness and viewing angle, although the small viewing area makes reading text challenging.
The case integrates two 3300mAh rechargeable batteries, which should keep the Pi and screen working for several hours. Networking is available using the 1 Gb Ethernet port or the Pi’s Wi-Fi module. A pair of speakers provides stereo sound output, which can be bypassed using a headphone plugged into the 3.5mm headphone jack.
CrowPi3: In Use
The unit turns on by pressing the right-side power button. A long press on the same button turns the unit off. Two red LEDs indicate whether the unit is charging and turned on. The cooling system is always on without temperature control and produces a low but noticeable whining sound from the fan. The built-in screen is more of a gimmick. An external display is recommended for actual development.
The Elecrow ecosystem builds on a customized version of Raspbian OS, specially tailored for interactive learning. The UI ditches the conventional desktop with icons and instead organizes items in what looks like a dashboard with two distinct sections. The left contains AI modules, while the right holds Python-based projects. The user must create an account to start using the CrowPi3.
The most challenging part of setting up the CrowPi3 is getting the OS up and running. Elecrow provides a 40GB image that, although containing a wealth of material, is just too big to be useful. In contrast, the latest Raspbian desktop image with recommended applications is less than 4 GB. Elecrow should provide a lite version of the OS with additional user packages external to the image.
CrowPi3: Competition
Very few platforms exist that are similar to the CrowPi3. With built-in modules that showcase the Pi’s ability to control peripherals and the various extension connectors spread around the case, the CrowPi3 is a unique product. The curated software library also plays an essential part in the product.
The Joy-Pi advanced product is similar to the CrowPi3 and supports Pi 4. It incorporates modules such as touch sensors and ultrasonic range finders and sports an even smaller 1-inch LCD. However, the price is higher than the CrowPi3, at more than $470. It lacks a battery and key components such as a camera to make an AI platform.
CrowPi3: Verdict
With their newest all-in-one station, Elecrow promotes an AI-centric product on a large scale through their Kickstarter campaign. The CrowPi3 feels well-built and oozes quality with many electronic modules, such as the LCD and touchscreen. However, the software support for voice and image recognition sets it apart from the competition. We liked the general appearance and portability of the platform, with a cute handle that completes the suitcase appearance. Don’t let the toy appearance fool you; the platform can be used for more serious stuff, such as software development, but with a bigger external screen.
That said, the unit feels overcrowded. Elecrow thinks cramming as many modules into a small space will win over the general public. The fact is that the platform might overwhelm beginners with its complexity. Also, supporting material such as schematics is missing. You are on your own if the unit breaks and you want to do some repairs. Finally, the fan is noisy and will be a distraction.
Buy it as a gift for kids who like building and breaking stuff.
Don’t buy it if you want to get your hands dirty quickly with the Pi5.
