CutiePi – a Raspberry Pi CM4 Linux Pill

A number of weeks in the past, I bought my palms on an early prototype of the CutiePi.

CutiePi – a Raspberry Pi CM4 Linux Pill

Not like many different Pi 'pill' tasks, this one is definitely extra of a, effectively, pill, since it's primarily based on the diminutive Compute Module 4. And due to that, and a {custom} major board, the CutiePi is lower than half as thick as the opposite respectable trendy Raspberry Pi pill in the marketplace, the RasPad—plus it has a cute deal with:

It has an 8" 1280x800 multi-touch show, a 5000 mAh battery, USB 2.0, USB-C energy (you should use the pill whereas charging), micro HDMI for an exterior monitor or TV, and a microphone, speaker, and 5MP 1080p rear-facing digicam.

However my favourite factor? The rear case pops off after eradicating eight #2 phillips-head screws! No pentalobe right here. Your complete design is made to be repairable (to a sure extent), and can also be open source, together with the {custom} CutiePi Shell UI, which is to date one of the best {custom} pill UI I've performed with on a Raspberry Pi (although... that is not saying a lot!).

CutiePi Shell

Being primarily based on a Raspberry Pi means you can too run different OSes, for instance Ubuntu 21.04, with its personal touch-based UI. Assist for that, and for another attention-grabbing use instances like being an exterior keyboard and touchpad in 'convergence mode', continues to be within the works.

Along with some transport woes, the pre-release software program I am utilizing nonetheless has some bugs which can be being ironed out. Actually, in the midst of making my video on the CutiePi, I discovered an MCU bug that prevented a tough reset in some situations, and that bug was fastened the subsequent day!

I wasn't anticipating an excessive amount of from the CutiePi, in spite of everything, 99% of the Raspberry Pi-based tablets are a touchscreen mounted to a cumbersome Raspberry Pi 4. This pill sells for $229, features a Compute Module, and is constructed with a custom-molded plastic enclosure.

The enclosure is pretty sturdy and has a pleasant grippy texture, however the display can scratch fairly simply, so if utilizing it for distant entry or tossing it in a bag with different issues, I would take into account a display protector.

Moreover the truth that the expertise is not buttery easy like even a low-end iPad, one different disappointment that I do not suppose is solvable with this specific design is the thermals are fairly constrained. Just a few minutes right into a stress-ng run ends in throttling, from 1.5 GHz to 1.2 GHz. The warmth from the Compute Module simply has nowhere to go after the skinny warmth sink is sizzling—plastic is a reasonably good insulator, and there are no vents to talk of:

I've a full evaluation of the board within the following YouTube video—please have a watch and see the way it handles YouTube, common searching, and RetroPie, then hold looking ahead to a full teardown!
