2. Soldering the headers
3. Plugging the board in
Once you have soldered the headers your 
board is ready to be placed into the desired 
mikroBUS™socket. Make sure to align the cut 
in the lower-right part of the board with the 
markings on the silkscreen at the mikroBUS™
socket. If all the pins are aligned 
correctly, push the board all the 
way into the socket.
Turn the board upward again. Make sure 
to align the headers so that they are 
perpendicular to the board, then solder the 
pins carefully.
Turn the board upside down so that 
the bottom side is facing you upwards. 
Place shorter pins of the header into the 
appropriate soldering pads.
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.
4. Essential features
DAC 3 click contains two analog output screw 
terminals: Vout and GND. 16-bit data is sent 
to the DAC through I2C. The digital value is 
converted to the appropriate voltage level 
in the range between GND and REFERENCE 
(VCC or 4.096V), which is proportional to 
the received 12-bit number. MCP4726 also 
integrates EEPROM for storing DAC register 
and conguration bit values.

DAC 3 click carries Microchip’s MCP4726, a 
12-bit digital-to-analog converter, along with 
voltage output screw terminals. The IC has 
EEPROM, congurable reference voltage, and 
communicates with the target board MCU 
through the mikroBUS™I2C interface (SCL, 
SDA pins). Standard (100 kHz), fast (400 
kHz) and highspeed (3.4 MHz) I2C modes are 
available. The board uses either a 3.3V or a 5V 
power supply. The board is suitable for sensor 
calibration, motor control, set point or oset 
trimming and many other applications.
