Waveshare's PocketTerm35 Turns Raspberry Pi into a Handheld Computer

Waveshare has unveiled the PocketTerm35, a handheld computer that leverages the Raspberry Pi ecosystem to create a portable computing device with a 3.5-inch touchscreen display and full QWERTY keyboard. The device represents an interesting approach to mobile computing, combining the flexibility of Raspberry Pi with a purpose-built handheld form factor.

The PocketTerm35 features a 640 x 480 pixel IPS touchscreen that provides adequate resolution for basic computing tasks and retro gaming. The display is complemented by a 67-key keyboard designed specifically for thumb typing, making it practical for on-the-go text input. For gaming enthusiasts, the device includes dedicated gaming buttons, expanding its utility beyond traditional computing applications.

Powering the device is a 5,000 mAh battery, which should provide reasonable usage time for a device of this class. The battery capacity suggests several hours of active use, though exact runtime will depend on the specific Raspberry Pi model and workload.

One of the most notable aspects of the PocketTerm35 is its modular approach to the Raspberry Pi itself. The device is designed to accommodate different Raspberry Pi models, and Waveshare offers several configuration options to match various user needs and budgets:

• PocketTerm35-Pi4 ($180): Includes Raspberry Pi 4 with 2GB RAM, 64GB microSD card with pre-installed OS, and 5,000 mAh battery
• PocketTerm35-Pi5 ($150): Includes Raspberry Pi 5 with 1GB RAM, 64GB microSD card with pre-installed OS, and 5,000 mAh battery
• PocketTerm35-RPI-ACC ($90): Device only, without battery, Raspberry Pi, microSD card, or power adapter
• PocketTerm35-RPI-ACCE-EN ($88): Device only, without Raspberry Pi, microSD card, battery, or power adapter

This tiered pricing strategy allows users to leverage existing Raspberry Pi hardware or choose their preferred model, making the PocketTerm35 accessible to a broader audience. The price difference between configurations reflects the cost of the included Raspberry Pi and accessories.

The device includes a RP2040 microprocessor that handles essential functions like keyboard input, display brightness control, and volume adjustment. This dedicated microcontroller offloads these tasks from the main Raspberry Pi processor, potentially improving overall system responsiveness and efficiency.

Connectivity options are comprehensive for a handheld device. The PocketTerm35 includes four USB Type-A ports, Gigabit Ethernet, a microSD card reader, and a headphone jack. These ports enable connection to peripherals, network access, and external storage expansion. The device supports USB Type-C charging, aligning with modern charging standards.

Audio capabilities include a 2W stereo speaker built into the device, providing adequate sound for gaming and media consumption without requiring external speakers or headphones.

In terms of physical design, the PocketTerm35 measures 168.5 x 93.5 x 37mm at its thickest point. This makes it approximately the height of a large smartphone but notably thicker and wider. While the "35" in the name might suggest pocketability, the device's dimensions make it more suitable for carrying in a bag or backpack rather than a typical pocket.

The construction features an aluminum front cover that provides durability and a premium feel, while the back is made of plastic to reduce weight and cost. The device includes battery status indicator lights for quick power level checks and features power and reset buttons on the back for easy access.

A significant design choice is the use of a standard Raspberry Pi Model B rather than the smaller Compute Module. This decision provides several advantages, including easier access to the full range of Raspberry Pi GPIO pins, compatibility with standard Raspberry Pi accessories and cases, and the ability to easily swap or upgrade the Raspberry Pi board in the future.

The PocketTerm35 supports Raspberry Pi OS and other Linux-based operating systems, giving users flexibility in software choice. This open approach allows for customization and the ability to run various applications, from productivity software to retro gaming emulators.

For developers and hobbyists, the PocketTerm35 offers an interesting platform for portable Raspberry Pi projects. The integrated display, keyboard, and battery make it suitable for field work, demonstrations, or as a dedicated portable development environment.

However, potential buyers should consider the device's limitations. The 3.5-inch screen, while adequate for basic tasks, may feel cramped for extended productivity work. The thickness, while necessary to accommodate the Raspberry Pi and battery, makes it less pocketable than dedicated handheld gaming devices or smartphones.

The PocketTerm35 represents an interesting niche in the handheld computing market, bridging the gap between traditional laptops and dedicated gaming handhelds. By leveraging the Raspberry Pi ecosystem, Waveshare has created a device that offers considerable flexibility and customization potential while maintaining a relatively accessible price point.

The device is available now through Waveshare's distribution channels, with the various configuration options catering to different user needs and existing hardware ownership scenarios. For Raspberry Pi enthusiasts looking for a portable computing solution or developers seeking a compact demonstration platform, the PocketTerm35 offers an intriguing option in the growing market of handheld Linux devices.
