This is a PHYTEC evaluation module with three LEDs and two input buttons that users can attach to the board expansion connector X16. Note that, due to compatibility with existing PHYTEC platforms using the phyBOARD-Segin carrier board such as i.MX6UL and STM32MP1, we face some hardware limitations and can thus only support one user LED (D2) and one button (S2) on the i.MX93 variant of the phyBOARD-Segin.
