General description

The TitanSBC-8Mmini (SLC5) is a new generation single board computer (SBC), based on energy efficient and fast 64-bit quad core industrial, heterogenous MPU NXP i.MX8Mmini, equipped with Cortex-A53 cores.
The main MPU of TitanSBC-8Mmini is equippped with real-time Cortex-M4 core, Gigabit Ethernet interface, video codec (H.265, H.264, VP8, VP9), PCIe 2.0 interface and another communication peripherals often used in industrial applications. Internal GPU offers up to 1080p60 resolution on HDMI interfaces with independent 2D (GC320) and 3D (Vivante GCNano Ultra) GPU engines. The MPU cores run at 1.8GHz without thermal throttling using the stock heat sink allowing a robust and quiet computer. The low-power LPDDR4 RAM memory used by default in TitanSBC-8Mmini computer additionally helps save energy.
The TitanSBC-8Mmini is equipped with on-board 1Gb/s Ethernet interface, half-duplex RS-485 interface, on-board RTC with external battery connector, audio codec (with headphone and microphone Jack connector and external speakers outputs), HDMI, 4 x USB 2.0 host connectors, 1 x USB-OTG connector, MIPI-CSI camera connector, PCIe 2.0 FPC connector (dedicated M.2 adapter available: SL-ADP-PCIe-M2), MicroSD card connector, DC/DC converter adapted to 12V external power supply.
Additionally the TitanSBC-8Mmini SBC is equipped with easy to use 2×20 pin connectors with 28 GPIOs for any use in user application.
The StarSBC-6ULL supports industrial grade embedded applications.
