PocketTerm35 is a portable handheld Linux terminal designed for Raspberry Pi 4B and Raspberry Pi 5 setups. It gives you a compact way to enter commands, run development tools, browse a graphical interface and handle day-to-day computing tasks away from the bench.
The unit combines a 3.5inch 640 × 480 optical bonding touch display with a 67-key QWERTY silicone keyboard, making it practical for CLI work, code entry and portable debugging. A built-in RP2040 handles control functions such as the keyboard, brightness and volume.
It also includes UPS power management for switching between Batt and external power, with support for external USB-C charging. Waveshare provides a wiki resource for setup and reference.

Jargon buster
Plain-language definitions for the technical terms used above.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- IPS
- IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.
- RP2040
- A microcontroller chip used on many maker boards, with enough speed and flexible I/O for some camera and display projects. Compatibility with RP2040 matters because camera modules often need many pins and careful timing to read image data successfully.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
