Mikroelektronika MIKROE-2396 R Meter Click Board, Resistance Measurement 0-1 Mega Ohm, SPI

Technical description of the product (MIKROE-2396):

The Mikroelektronika MIKROE-2396 R Meter Click Board is a resistance meter with a 0 to 1 Mega Ohm range and SPI interface, designed for 5V operation. The analog output is fed through a 12-bit ADC, with the final output routed via the mikroBUS™. Due to the ADC\'s limited min-max range (0-2043), the R Meter Click Board employs a multiplexer that adjusts the input signal to the amplifier, allowing the same ADC to measure four distinct value scopes (0-1k, 1k-100k, 100k-1M). The provided firmware (available on Libstock) automatically scans the ADC value and switches the multiplexer output based on the installed resistor. The multiplexer interfaces directly with the target board MCU through mikroBUS™ S1, S2, and S3 pins (replacing the default mikroBUS™ PWM, INT, and RST pins). Onboard screw terminals facilitate use with multimeter probes. The board is designed for a 5V power supply.
