Makers and hackers would be able to transform old mobile phones into single-board computers designed for Linux with the aid of a Belgian company called Citronics, according to online tech journal Hackaday.
The company uses a prototyping breakout board for a Fairphone 2, offering 4x USB2, 1x 10/100M Ethernet, and a Raspberry Pi header with UART, SPI, I2C and GPIO connectivity, but lacks a screen and camera.
The unit runs Linux, mainly PostmarketOS, which can support 250 devices, with stripped cameras and screens that are often easily broken and have limited Linux support.
The journal said it lacks specifics on the breakout boards but asked when an open-source version might appear, given the abundance of second-hand, cheap or broken cellphones.
