IoT-centric Linux ready SBC has an optional enclosure

Dec 15, 2017 — by Rick Lehrbaum 1,519 views

Technologic’s TS-7553-V2 SBC runs Linux on an i.MX6UL and offers Ethernet, USB, GPIO, and serial I/O, plus WiFi/BT, XBee, cellular, and many other options.

Technologic’s new “TS-7553-V2” single-board computer is a gen-2 re-spin of its 250MHz Cavium ARM9 SoC-based TS-7553 SBC. The new board upgrades the processor to the 698MHz-clocked NXP i.MX6UL, and then for good measure increases RAM to 256MB (up from 64MB) and flash storage to as much as 64GB (up from 256MB), while expanding the board’s fanless operating temperature range to -40 to 85°C (from 0 to 70°C). It also adds several built-in interfaces, such as for connection of text LCDs and matrix keyboards, and supports more modular expansion options than its predecessor.

As pictured above, Technologic offers an optional “EN820” enclosure for the TS-7553-V2 SBC. The enclosure can be ordered with or without the backlit 128 x 64px matrix LCD and 4-button keypad that connects to the SBC’s HMI interface. An optional DIN rail mounting bracket is available.

In addition to its Ethernet, WiFi, Bluetooth, and CAN connectivity, you can configure the TS-7553-V2 SBC with modules that support cellular, DigiMesh, ZigBee, and Lora communications, making it suitable for IoT node or gateway applications. There’s also an optional 9-axis MEMS motion tracking module with internal gyroscope, accelerometer, and compass functions, which could be useful for asset management applications, or in situations requiring motion or vibration sensing.
