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 Pressure 2 click 2 3 4. Essential features The MS5803-14BA is both precise and ro- bust. The measurement resolution is up to 0.2 mbars, but an antimagnetic stainless steel cap enclosure allows it to withstand up to 30 bars of pressure (more than twice the maximum measurement range). Therefore, Turn the board upside down so that Turn the board upward again. Make sure Pressure 2 click is ideal for developing mo- the bottom side is facing you upwards. to align the headers so that they are bile pressure measurement systems, such Place shorter pins of the header into the perpendicular to the board, then solder the as for adventure watches, diving computers appropriate soldering pads. pins carefully. and similar devices. 1.
