      Description

      Our TM3+HB8/9LT SBC provides a cost effective SBC for those that do not require HDMI, USB3 or PCIe. A range of interfaces with industry standard connectors and supports a 6-36Vdc DC voltage power input. (Note: When used in conjunction with our standard 12” LCD HB9 the LCD backlight only operate with a from 12-36Vdc)

      HB8LT supports our 4.3” or 7” LCD with capacitive or resistive touch.

      HB9LT supports our 9.7” or 12” LCD with capacitive touch

      When headless operation is required then we recommend use of the HB8 LT as this is our highest volume configuration and therefore the most available.  

      Using our TM3 it is the ideal module for a cost effective Internet of Things (IoT) device. The TM3+HB8/9LT can be used where Wi-Fi, Bluetooth and/or Ethernet is required. A 2G, 3G , 4G or 5G modem can be added via USB2 to offer cellular connection. Together with three asynchronous RS232/422/485 ports, the TM3+HB8/9LT is an extremely versatile host board which can support a wide range of applications.

      The TM3+HB8/9LT is also available in our Beta range of embedded touch display modules by combining it with our LCD, touchscreen, mechanicals, cables and Android or Linux operating systems. Ubuntu, Devicetree and Yocto based BalenaOS are supported.

      If you require something a little different we can provide the schematics for the carrier board free of charge (under NDA) to help you create your new product as quickly and as risk-free as possible. Please contact us for further details.
