Variscite is developing a 55 x 30mm system-on-module around NXP’s i.MX 91 processor IC, which has a 1.4GHz Cortex-A55 core.
Named DART-MX91, the board will be equipped LPDDR4 memory between 512 Mbyte and 2Gbyte depending on options selected, and eMMC storage between 8 and 64Gbyte.
Interfaces include: dual CAN-FD, dual Gigabit Ethernet, dual USB, Bluetooth 5.4 and Wi-Fi6 802.11 ax/ac/a/b/g/n. 802.15.4 is an option, and if no Wi-Fi at all is fitted an extra IO port can be enabled.
Operation is over 0 to +70°C, -25 to 85°C or -40 to 85°C depending on selected options.
Accessories include a suitable heatsink, an antenna for the wireless interfaces, a carrier board and a power supply.
The carrier board – VAR-DT8MCustomBoard as it is known – turns the module into a stand-alone computer, adding connectors and PHYs (interface hardware) for Gigabit Ethernet, cameras, LVDS and PCIe, as well as a real-time clock.
