Comparator mikroBUS Module, LM2903 (Comparator click) US$12.00

MIKROE-1915
Comparator mikroBUS Module, LM2903 (Comparator click)


  • LM2903 low-power dual-voltage comparator
  • Range: 2V to 36V DC single voltage; 1V to 18V DC dual voltage
  • High precision: 2mV offset voltage
  • Two pairs of input screw terminals and two potentiomters
  • 3.3V or 5V logic level
  • Comparator click features TI's LM2903 dual-differential comparator IC. Two pairs of screw terminals allow you to connect separate inputs (the additional two screw terminals are for GND connections). You can use it either with a single (range of 2.0V DC to 36V DC) or dual power supply (from 1.0V DC to 18V DC). The resulting output is compatible with TTL, DTL, ECL, MOS and CMOS logic systems.

    Two potentiometers are placed between the terminals and the IC. Each input has its own Interrupt pin on the mikroBUS socket (one on the INT pin; the other in place of the mikroBUS AN pin), here marked 01 and 02.

    A solder jumper on the board allows you to select whether 3.3V or 5V logic level is used on the interrupt pins. It is in the 3.3V position by default.

    Note: The picture shows the board with through-hole headers. The board now comes populated with male pin headers already soldered for your convenience. The board's user manual has yet to be updated to remove the soldering instructions.

    mikroBUS Click Boards Overview

    Click boards plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. The sockets are found on Clicker boards, the Flip & Click Arduino/Python-compatible board, the Quail board, these mikromedia shields, the Microchip Curiosity board, and development systems from mikroElektronika (V7 systems and later).

    You also can connect Click boards to many other popular platforms via these adapters:

    • PC Click USB Adapter (MIKROE-1433)
    • Arduino Arduino UNO click shield (MIKROE-1581) or Arduino Mega click shield (MIKROE-1900)
    • Raspberry Pi Pi click shield (MIKROE-1512) or Pi 2 click shield (MIKROE-1879)
    • BeagleBone Black BeagleBone click shield (MIKROE-1596) or mikroBUS Cape (MIKROE-1857)
    • STM32F3 Discovery STM32F3 Discovery Shield (MIKROE-1447)
    • STM32F4 Discovery STM32F4 Discovery Shield (MIKROE-1481)
    • Stellaris LM4F120 LaunchPad / Tiva TM4C123G LaunchPad Click BOOSTER PACK (MIKROE-1363)
    • Freescale Freedom — FRDM-KL46Z click shield (MIKROE-1795) or FRDM-K64F click shield (MIKROE-1794)

    In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
