FBM230 P0926GU Low Power Device Modules

Secondary touch surfaces can be placed both inside and outside the vehicle, such as handlebars, doors, electronic mirrors, control grips, steering wheels, between seats or on armrests. Using the FBM230 P0926GU’s low-power wait-for-touch mode consumes less than 50 ohms A, keeping it responsive to the user even when the display is turned off to save power or avoid disturbing the driver at night. The system will wake up to a touch event anywhere on the touch surface.

In addition, the FBM230 P0926GU device is capable of detecting and tracking multi-fingered thick gloves through a variety of cover materials and thicknesses, such as leather, wood, or uneven surfaces, even when wet. Typically, the dielectric constants of these cover materials would limit touch detection, but these devices offer a solution to detect and track multi-fingered high signal-to-noise ratio (SRR) and through a proprietary differential mutual acquisition scheme. For example, in car-sharing applications, this touch functionality helps users access the car from the outside by tracking touch coordinates on an external display in any environment, such as rain, snow or extreme heat. Motorbikes and other scooters also benefit from this weatherproof design.

There is both software and hardware support. Software tools include Mexter Studio and Mexter Analyser. For the FBM230 P0926GU the hardware supplied includes: Evaluation Kit with printed circuit board and 5″ capacitive touch pad, and for the FBM230 P0926GU the Evaluation Kit includes PCBs and a 2.9″ capacitive touch pad. For both devices, the bridge board includes a USB connection for connection to a computer.
