Ka-Ro’s rugged, SODIMM-style “TXSD-410E” COM runs Linux with U-Boot on a Snapdragon 410E, and offers WiFi, Bluetooth, LVDS, and a choice of dev kits.
The 68 x 26 x 4mm TXSD-410E — or just plain TXSD — is part of Ka-Ro Electronincs’ pin-compatible TX family of SODIMM-style computer-on-modules, all of which feature 10-year guaranteed availability. Recent TX modules include TX6 series COMs based on the i.MX6 and i.MX6 UltraLite (TX6UL), as well as the Atmel SAMA5D42 based TXA5. There have been more than 1 million TX installations since the form factor’s debut in 2003, says Ka-Ro.

The TXSD expands upon Qualcomm’s embedded 410E version of the Snapdragon 410. The Snapdragon 410E appeared this week on an F&S Pico-ITX SBC called the armStone A53SD. Other 410E-based COMs include the 50 x 28mm Inforce 6301.
The quad-core, 1.2GHz Cortex-A53 Snapdragon 410E integrates an Adreno 306 GPU and a Hexagon DSP, among other goodies. The module supports Android and Windows 10, but as a default ships with a modified version of Qualcomm’s Ubuntu/Linaro 4.4.9 distribution.
This is the first Snapdragon-based embedded board with pre-configured U-Boot, claimed Ka-Ro North America’s Manager of Business Development, Bob Blumenscheid, in an email. “This allows for easy on-module and customer peripheral configuration, and for updating products in the field,” he wrote. “Our BSPs are continuously updated to the latest mainline kernel, giving our customers access to the latest kernel, and the latest drivers, fixes and security updates.”
The TXSD’s most unique attribute, however, is its native, on-module LVDS support, wrote Blumenscheid. “Almost all other modules use MIPI displays, designed for consumer products,” he wrote. “LVDS displays are available with greater product longevity, and more ruggedized connectors than the MIPI displays.” The onboard, driver-supported LVDS interface also avoids the need to purchase and install a MIPI-to-LVDS converter.

Other notable features include an extended -25 to 85°C temperature range, as well as onboard 2.4GHz 802.11b/g/n and Bluetooth 4.0 radios. The module ships with 1GB LPDDR3 and 4GB eMMC, which can be configured to 2GB in high-reliability pseudoSLC mode.
The TXSD lacks Ethernet support, but provides signals for USB 2.0, SD, configurable GPIOs, and 6x UART, SPI, and I2C interfaces. The LVDS interface is accompanied by a 1280 x 720 LCD controller, and there are dual MIPI-CSI camera interfaces with support for 720p video encode. The module runs on 5V or battery power, and delivers 1.8V I/O voltage. Pinout assignments are documented in detail.

Ka-Ro supports the module with a TXSD-70 baseboard, which can bought alone, or as part of a $650 TXSD-SV71 development kit that includes the module and a 5.7-inch capacitive touchscreen. No more details were provided, but this appears to be the standard TX Mainboard 7 carrier board and dev kit available with the TX6UL.
The TXSD Development Kit featuring the TXSD-410E module is available with a 5.7-inch capacitive touchscreen for $650. Prototyping quantities of the TXSD-410E on its own will begin shipping in mid-April for $115 in single units, followed by volume availability in early Q3 2017. Quantity discounts apply. More information may be found on the Ka-Ro TXSD-410E and TXSD-410E dev kit shopping pages.
Ka-Ro Electronics will showcase the product at Embedded World in Nuremberg on Mar. 14-16 in Hall 4A, Booth 320. The TXSD will also be shown in the booths of Arrow Electronics and Glyn, Ka-Ro’s distributor in Germany.
