The Raspberry Pi boards are used in a countless number of projects, and some of those turn one of Raspberry Pi boards into a (thick) smartphone powered by Linux. The first one was probably PiPhone based on Raspberry Pi 1 Model B, and other followed suit such as TyTelli based on Raspberry Pi Model A+, and more recently ZeroPhone powered, as its name implies, by Raspberry Pi Zero board.
PiTalk board specifications:

The board can be controlled with Python code, but the company did not provide any details at this stage. A PiTalk GUI interface to control the board will also be offered, and the Open Hardware and Open Software logo are shown on the Kickstarter page, but again no detailed information about that part.
PiTalk has launched on Kickstarter with a 10,000 GBP funding target. Rewards start at 47 GBP ($63) for PiTalk boad and an antenna, but if you need a kit, you’ll need to pledge 65 GBP ($87) and up starting with the 3.2″ LCD kit. Shipping adds 3 GBP to the UK, and 10 GBP to the rest of the world, and you can expect the rewards to ship in March 2018 if the project can be completed on time.
