A 1.46 x 0.08 inch x 0.062 inch thick (37 x 2 x 1.6 mm) PCB for demonstrating 1.1 x 1.1 mm DFN4/DFN4 sensors (-14E sensor suffix; order sensors separately). Note that since these boards use very small sensors, they require reflow or hot-air soldering techniques.
This product is a longer, skinnier version of part number AG904-06. The board width is 3 mm maximum (where the header pins are) and is tapered down to 2 mm for a 25 mm long path to the sensor.
