Solectrix SX Mobile Device Kit Runs Linux or Android on NXP i.MX8M Mini Processor

In the last two years or so, we’ve seen the development of Linux phones that are expected to launch in the next few months with products such as PinePhone, Purism Librem 5, or even Necunos NC_1.

Solectrix SX Mobile Device Kit also targets Arm-based mobile devices, but it is somewhat different, as the i.MX8M Mini development kit aims to help with the design of Android or Linux mobile devices with software, hardware and housing available, but more geared towards specific business use cases, as it comes with optional Gigabit Ethernet and USB-to-UART ports, and no cellular connectivity.
