Avalue RSC-IMX61 NXP i.MX 6Quad and 6DualLite 3.5" SBCs with 12 to 26 V DC Input and Wide Temperature

Panels and controllers in factories, vehicles and building plant rooms often run for a decade, and the board inside them needs a stable processor, a forgiving power input and an operating range that copes with a warm cabinet. The Avalue RSC-IMX61 series is a family of NXP i.MX6 3.5″ SBCs on a 146 x 102 mm board, rated from -20 to 85 °C with a 12 to 26 V DC input and a passive heatsink.

Both boards use NXP i.MX6 Cortex-A9 processors at 1 GHz with 1 GB of DDR3 memory soldered to the board, 8 GB of eMMC and a microSD socket. Avalue lists Android 4.4.2 and 6.0, Ubuntu 12.04 and Yocto 2.1, which suits long-running HMI and controller images already qualified on the i.MX6. The processor sets the core count, so the choice comes down to software load, and a battery connector keeps the real-time clock running through power loss.

The range has two builds. RSC-IMX61-3W-A200R uses the two-core i.MX 6DualLite, a good fit for a single HMI application or a gateway. RSC-IMX61-3W-A201R uses the four-core i.MX 6Quad for heavier interfaces or several services at once, and its datasheet lists an optional SATA connector with SATA power that the DualLite board lacks.

I/O is shared. HDMI with a screw lock and 24-bit dual-channel LVDS run two displays together, with a backlight control header for the panel. One GbE RJ45 port uses a Micrel KSZ9031RNX PHY, and the datasheet lists an optional 802.3at powered LAN input. USB covers two Type-A ports, a Mini USB OTG port and an internal header, with one RS-232 header, one CAN port and a 10-bit GPIO header for machine signals. 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. A hidden reset button, power and Wi-Fi LEDs and an optional IR receiver jack sit on the rear edge.

Power is 12 to 26 V DC on a barrel connector, typically 19 V, with brownout detection and AT power-on when input is applied. With CE and FCC compliance and 0 to 90% non-condensing humidity, the RSC-IMX61 series suits operator panels, transport and passenger information displays, kiosks, building automation controllers and test equipment that needs a long-life Arm board.
