Status:
POT 5 Click is a compact add-on board with accurate selectable reference voltage output. This board features the PDB081-P10-103B1, a high-quality 8mm micro rotary 10k potentiometer from Bourns. The PDB081-P10-103B1 potentiometers operate over a wide temperature range, withstanding 50V maximum voltage. This rotary potentiometer offers 5Ω maximum resistance, 0.03W power rating, and 100mV maximum sliding noise. This Click board™ can be used in any application that requires an analog or digitized control voltage, HMI applications, test, measurement, or laboratory equipment.
POT 5 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

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 either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for either 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.

We provide a library for the POT 5 Click as well as a demo application (example), developed using Mikroe compilers. The demo can run on all the main Mikroe development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.
Library Description
This library contains API for POT 5 Click driver.
Key functions
pot5_read_voltage
This function reads raw ADC value and converts it to proportional voltage level.
pot5_convert_voltage_to_percents
This function converts analog voltage to potentiometer position in percents.
pot5_set_vref
This function sets the voltage reference for POT 5 click driver.
Example Description
This example demonstrates the use of POT 5 click board by reading and displaying the potentiometer position.
void application_task ( void )
{
float voltage = 0;
if ( POT5_OK == pot5_read_voltage ( &pot5, &voltage ) )
{
log_printf( &logger, " AN Voltage : %.3f Vrn", voltage );
log_printf( &logger, " Potentiometer : %u %%rnn",
( uint16_t ) pot5_convert_voltage_to_percents ( &pot5, voltage ) );
Delay_ms( 1000 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all Mikroe compilers.
This Click board™ is supported with mikroSDK - Mikroe Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
