POT 5 Click is based on the PDB081-P10-103B1, a high-quality 8mm micro rotary 10k potentiometer from Bourns, providing very accurate voltage output. The PDB081-P10-103B1 features a 1mm plastic shaft (2mm pin length), low profile, without detent, and linear tapers. This potentiometer operates over a wide temperature range, withstanding 50V maximum voltage. This rotary potentiometer offers 5Ω maximum residual resistance, 0.03W power rating, and 100mV maximum sliding noise. Its typical applications include consumer white goods, test and measurement equipment, communications and laboratory equipment, and other applications requiring an analog or digitized control voltage.

The output signal of the PDB081-P10-103B1 can be converted to a digital value using MCP3221, a successive approximation A/D converter with a 12-bit resolution from Microchip using a 2-wire I2C compatible interface, or can be sent directly to an analog pin of the mikroBUS™ socket labeled as AN. The selection can be performed by using an onboard SMD switch labeled as VSEL, placing it in an appropriate position marked as AN or ADC.

This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
