pablopl/muxpi

MuxPi is an open hardware and open software board which was designed to aid in automating tasks on physical devices. Initial goal was to automate testing on hardware platform, thus connected devices will be called Device Under Test or shortly DUT. Muxpi is intended to help in testing of embedded systems, automatic software installation or flashing and automation during development. MuxPi is connected between the DUT and a PC/Server machine which will be managing the work. The name of the board is based on its two main components: SD Mux and NanoPi.

Features

• Providing a DUT connection (UART, USB, ETH, microSD card) to remote location over Ethernet
• Switching a microSD card between a DUT's microSD card slot and an onboard USB card reader
• Flashing a microSD card using an onboard USB card reader
• Flashing and controlling state of Samsung mobile devices over fully controllable, dedicated USB interface
• Switching DUT's power supply
• Switching jumpers/buttons of a DUT in order to (re)boot/(re)configure it
• Measuring power consumption of a DUT
• Handling serial connection (UART) of a DUT
• Writing EDID to a DUT over HDMI connection
• Interacting with a user/maintainer over a simple, bidirectional interface
