2. Soldering the headers Before using your click board, make sure to solder the provided 1x8 male headers to both sides of the board. Two 1x8 male headers are included with the board in the package. 1 DIGIPOT click 2 3 1. Introduction 4. Driving the board There are four screw terminals available for further connections: PA, PB, PW and GND. Turn the board upside down, so that Turn the board upward again. Make sure Data is sent to the board using industry bottom side is facing you upwards. Place to align the headers so that they are standard SPI communication interface. shorter parts of the header pins in the perpendicular to the board, then solder the On-board controller converts the received Front and back side appearance both soldering pad locations. pins carefully. digital value to the appropriate linearly of the DIGIPOT click Board proportional resistance value. DIGIPOT Click is an accessory board in mikroBus form factor. It features 3.

Power supply selection 5. DIGIPOT click Board Schematics On-board PWR SEL zero- ohm resistor (SMD jumper) is used to determine whether 5V or 3.3V power supply is used. This resistor is provided in 3.3V position by default. In order to use DIGIPOT click with 5V development VCC J1 system, it is necessary to resolder this jumper PWR SEL to 5V position. +3V3 +5V VCC AN PWM RST INT CS R1 CS RX SCK 2K2 7.
