Avalue RSC-IMX61-3W-A200R NXP i.MX 6DualLite 3.5″ SBC with 12 to 26 V DC Input and Wide Temperature

Many HMIs and gateways run one application for years on end, and the board inside them needs to start reliably on a cabinet or vehicle supply and keep going in a warm enclosure. The RSC-IMX61-3W-A200R is the dual-core build in the Avalue RSC-IMX61 series, an NXP i.MX 6DualLite 3.5″ SBC on a 146 x 102 mm board, rated from -20 to 85 °C on a 12 to 26 V DC input.

The NXP i.MX 6DualLite provides two Arm Cortex-A9 cores at 1 GHz, matched with 1 GB of DDR3 memory soldered to the board, 8 GB of eMMC and a microSD socket. That suits a single HMI, a protocol gateway or a passenger information display, where power draw and heat stay modest. Avalue lists Android 4.4.2 and 6.0, Ubuntu 12.04 and Yocto 2.1 for the board.

Displays connect through HDMI with a screw lock and 24-bit dual-channel LVDS, running together for an internal panel and an external screen. One GbE RJ45 port uses a Micrel KSZ9031RNX PHY. USB covers two Type-A ports, a Mini USB OTG port and an internal header, and one RS-232 header, one CAN port and a 10-bit GPIO header connect controllers, vehicle networks and switches. A half-size mPCIe slot with PCIe and USB signals takes a Wi-Fi or cellular module, and audio covers line-out, speaker and microphone.

Power is 12 to 26 V DC on a barrel connector, typically 19 V, with brownout detection and AT power-on, so the board restarts on its own after a supply drop. It cools through a passive heatsink and carries CE and FCC compliance. For heavier interfaces, the quad-core RSC-IMX61-3W-A201R adds two more cores and an optional SATA connector. The RSC-IMX61-3W-A200R suits HMIs, transport displays and building controllers.
