PicoCalc is a new handheld that is based on a Raspberry Pi and comes with a dedicated keyboard for text input. Design wise, the device is clearly inspired by a calculator, although there are significant limitations in terms of performance.

We've already reported on the manufacturer Clockwork several times, as the company offers various mobile devices, particularly for the Raspberry Pi. These are generally designed for enthusiasts, hobbyists and tinkerers and probably less for regular productive users, and the new PicoCalc is certainly no exception to this rule.

As the name already implies, the device obviously resembles an old-school calculator. It sports a keyboard with a regular US layout that might be inconvenient to use for international tinkerers. That said, the keyboard comes with a directional pad and function keys. All keys are backlit and there are secondary assignments for some keys.

The handheld features a 4-inch screen with a resolution of 320 x 320 pixels, the IPS panel is connected via SPI. The actual chipset needs to be installed manually, as the system supports both a first and second generation Raspberry Pi Pico. Accordingly, performance is not even remotely on the level of full-fledged laptops or gaming handhelds. On the other hand, the PicoCalc doesn’t need much power and can run on 18650 batteries. Speakers are built-in as well, and the aforementioned display is protected by tempered glass.

The PicoCalc Kit is available for a price of $75, which includes a 32GB SD card with an optimized firmware. A Raspberry Pi Pico 1 H is included in this kit. 3D files are available and make it pretty easy to modify this new interesting handheld.
