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 ADC 2 click 2 3 4. Essential features ADC 2 click, because of the low noise and high oversampling rate of MCP3551, is ideal for high accuracy applications. Measurements from analog pressure, temperature and hu- midity sensors, for example. The board carries two pairs of screw screw terminals: VIN- for Turn the board upside down so that Turn the board upward again. Make sure bringing in reference voltage, VIN+ for the the bottom side is facing you upwards. to align the headers so that they are positive voltage. VCC out and GND are output Place shorter pins of the header into the perpendicular to the board, then solder the voltages. ADC 2 click also has an extended appropriate soldering pads. pins carefully. temperature range (-40C to +125C). 1. Introduction ADC 2 click carries MCP3551/3, which is a 3.
