This is computer in brick-like form factor, resembling overgrown calculator.
It contains Raspberry Pi Zero inside, plus WiFi module, some power management. It has 320x240 TFT as display, 4x4 keyboard as input device and analog joystick as pointing device. Along with that two full-size USB A connectors, one 3,5mm jack for headphones and 2x6 pni 0,1" header with some PGIO of RPi Zero broken out. The keyboard and "trackpad" interface si very spartan, but it's included all in single enclosure and gives the rudimentary means of controlling the device. External keyboard or mouse is possible to increase user comfort, but not needed.
It sports Raspbian Linux, with all the software you can run in 320x240 display.
This is still under development. It will have larger display and qwerty keyboard.
Q: How is this better than my phone/tablet/smart toaster?
A: If you need to ask this question, then it isn't any better.
Is this being sold anywhere?
