Card-Sized PC "CardputerZero" with Raspberry Pi Zero 2W Announced

A Card-Sized Full-Fledged Linux PC M5Stack

has announced the “CardputerZero,” a pocket-sized computer that integrates a display, keyboard, and battery into a business card-sized case. The crowdfunding campaign for this device has launched on Kickstarter. Equipped with the same processor as the Raspberry Pi Zero 2W, the CardputerZero is garnering attention as a compact yet full-fledged PC capable of running Linux-based software. Previous models in the Cardputer series were powered by the ESP32 microprocessor, which lacked sufficient memory to support Linux. However, the new CardputerZero overcomes this limitation by employing the Raspberry Pi Compute Module 0.

Performance Equivalent to Raspberry Pi Zero

2W At the heart of the CardputerZero is the Broadcom BCM2710A1 quad-core Arm Cortex-A53 processor, the same one found in the Raspberry Pi Zero 2W. It comes with 512MB of LPDDR2 memory and supports wireless features like WiFi 4 and Bluetooth 4.2 LE. The device features a 1.9-inch LCD panel with a resolution of 320×240 pixels and 262,000 colors. Alongside improved processing capability, the device’s input and output functionalities have been significantly enhanced.

Two Models and Pricing Two models of the

CardputerZero are available on Kickstarter. The standard version is priced at $119 during the crowdfunding period and includes a 32GB microSD card, an 8MP camera, a gyroscope, and an accelerometer. For those looking for a more affordable option, the entry-level CardputerZero Lite is available for $89. This version does not come with a camera, motion sensors, or an SD card. However, both models share the same processor and display specifications. In comparison, the earlier ESP32-based model, the Cardputer Adv, was sold for $30. The significant price increase for the new model is attributed to the integration of the Raspberry Pi Compute Module 0 and the enhanced capabilities brought by Linux compatibility.

Extensive Interface Options Despite its

compact dimensions of 85×54×23.1 millimeters, roughly the size of a stack of business cards, the CardputerZero is packed with an impressive range of interfaces. The device features an HDMI port for video output supporting 1080p at 30fps. It includes three USB ports: two USB 2.0 Type-C ports and one USB Type-A port. Additionally, it has a 10/100 Ethernet port for wired network connectivity. Audio capabilities include a 3.5mm headphone jack and a built-in 1-watt speaker. For storage, the device is equipped with a microSD card slot. The expansion port allows access to interfaces such as I2C, SPI, UART, USB, GPIO, and 5V power, enabling connections to optional LoRa modules, Grove modules, and other M5Stack accessories.

Practicality in Your Pocket The CardputerZero

features a 1,500mAh battery and an integrated infrared transmitter and receiver. While its 46-key matrix keyboard may not be ideal for long typing sessions, having a built-in keyboard is a significant advantage for a portable device. When compared to a similar compact device currently under development, the Flipper One, the latter boasts a faster processor, high-speed wired and wireless networking, faster USB ports, and an M.2 slot for 4G or 5G modules. However, the CardputerZero stands out for its high level of integration, combining a keyboard and display into a ready-to-use pocket PC. Thanks to its Linux compatibility, the CardputerZero is suitable for a variety of use cases, such as terminal operations, lightweight programming environments, IoT device control, and network device management. Its business card-sized form factor makes it a portable Linux machine, an appealing concept for tech enthusiasts and developers.
