Avalue ACP-IMX6POS-B1 NXP i.MX 6Quad Arm SBCs with 12 to 24 V DC Input, Dual GbE and Wide Temperature

Terminals installed beside machines, in unheated halls or inside outdoor kiosks need more than an office-grade board: a wider temperature range, a second network port and a power input that tolerates the supply on site. The Avalue ACP-IMX6POS-B1 series answers that with NXP i.MX 6Quad Arm SBCs on a 175 x 110 mm board, rated from -20 to 85 °C and cooled by a passive heatsink with no fan.

Compute comes from the NXP i.MX 6Quad, four Arm Cortex-A9 cores at 1 GHz, with 2 GB of DDR3L memory soldered to the board. Storage is 8 GB of onboard eMMC plus a microSD socket for logs, media or field updates. Avalue supplies the boards with Yocto 2.5, a Linux build suited to long-running embedded images, and the board includes a watchdog function to recover from a stalled application.

Two GbE RJ45 ports, from the i.MX6 MAC with a Micrel KSZ9031RNX PHY and from an Intel I211 controller, let one port face the machine network and the other the plant network. Displays connect through HDMI, VGA and 24-bit dual-channel LVDS, with any two running together. Two DB9 ports carry RS-232/422/485 with auto flow control on RS-485, two internal headers carry RS-232, and a 16-bit GPIO header handles buttons, lamps and sensors. USB covers two Type-A ports, a Mini USB OTG port and three internal headers, and a full-size mPCIe slot with USB signals and a SIM socket take an optional wireless or cellular module. A backlight connector, a front panel connector and an I2C header support panel builds.

The range is one build: ACP-IMX6POS-B1R with the i.MX 6Quad, 2 GB of memory, dual GbE and the full -20 to 85 °C rating. It keeps one bill of materials across indoor and harsher sites.

Power arrives as 12 to 24 V DC on either a barrel connector or a 4-pin header, so the board can take a bench adaptor during development and a wired cabinet supply in service. With CE and FCC compliance and 0 to 90% non-condensing humidity, the ACP-IMX6POS-B1 series suits factory operator terminals, outdoor kiosks, transport ticketing and digital signage in enclosures that see wide temperature swings. The aluminum CPU heatsink measures 41 x 41 x 20 mm, so allow that height when planning the enclosure.
