2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 UNI HALL click 4. Essential features 2 3 The unipolar Hall eect ff sensor on UNI HALL click is sensitive to north pole magnetic 1. Introduction fieldswhen exposed to such a field, it outputs a LOW logic level. Othewise the output is a HIGH logic level. In its simplest application, UNI HALL click can be employed as part of a long lasting contactless proximity switch. However, magnets can Turn the board upside down so that Turn the board upward again. Make sure be employed in various ways to infer the the bottom side is facing you upwards. to align the headers so that they are speed, position, or other properties of an Place shorter pins of the header into the perpendicular to the board, then solder object there are countless ways to utilize appropriate soldering pads. the pins carefully. UNI HALL click in your design. UNI HALL click is a simple solution for adding an unipolar Hall switch to 3. Plugging the board in your design. It carries the Melexis click US5881 unipolar Hall-effect switch and Once you have soldered the headers your a 74LVC1T45 single bit, dual supply board is ready to be placed into the desired BOARD translating transceiver. UNI HALL click mikroBUS socket. Make sure to align the www.mikroe.com communicates with the target board cut in the lower-right part of the board with through the mikroBUS INT line. The the markings on the silkscreen at the UNI HALL click manual board is designed to use either a 3.3V or mikroBUS socket. If all the pins ver. 1.00 5V power supply (which also defines the are aligned correctly, push the logic level of the output signal). board all the way into the socket. 0 100000 026939 5.
