Smart display I/O expansion shield

19 July 2017 Computer/Embedded Technology

With the objective of helping both the maker community and professional engineers, Bridgetek is continuing to add new hardware to its CleO smart display platform. Compatible with both the CleO35 3,5” and CleO50 5” TFT formats, the new CleOIO-Shield is an input/output expansion shield that connects directly on to the NerO system controller board. It provides the CleO system with greater interfacing capabilities covering analog, digital, I²C, SPI and UART.

The additional I/O functions made available by this shield can be connected through either the CleO’s Arduino Uno interface, a MikroBus header or the Grove-Universal 4-pin connector option. The new shield (which measures 70 x 53 x 21 mm) comes with a collection of daughter boards as part of the package, offering engineers a variety of different functions that can be easily integrated into their design. A rotary potentiometer module, a temperature/humidity sensing module, a voltmeter module, a light sensing module and a microphone module are all included. In addition, an FM radio functional block plus a 4-pin to 2-pin x 2 speaker cable are included.

The company also introduced two more development modules for its award-winning Embedded Video Engine (EVE) graphics controllers. The ME812AU-WH50R and ME813AU-WH50C have resistive and capacitive touchscreens respectively. Each of them features a 5,0”, 800 x 480 pixel resolution TFT display (with a bezel for the ME812AU-WH50R version) supporting both landscape and portrait viewing modes. Dimmable backlighting and audio amplifier (capable of driving a 1 W speaker) functions are incorporated. Thanks to their built-in USB-to-SPI bridging technology, these modules act as USB peripheral devices and are thus straightforward to access from a PC or any other form of USB host.
