Overview

The MBI5124 is a LED Driver for 16 constant current outputs, for set the current is necessary only one resistor, the maximum current for output is 25mA @ 5VDC and 10mA @3.3VDC. The Breakout board is controlled by shift register bus, (SI, SCLK, LE, OE). The breakout board has sixteen constant current outputs ready for use and is possible to connect multiple break boards.

Breakout Board Ready for use in Arduino

The 16-channel Expandable Breakout Board is a versatile and user-friendly device designed to interface with an Arduino or similar microcontroller platform. It offers 16 individual output channels.

This breakout board simplifies the process of controlling various external devices, such as LEDs, relays, solenoids, and more. It comes equipped with a unique feature that allows users to adjust the current for all 16 channels collectively using just one resistor. This flexibility provides ease of use while ensuring precise current output control.

Features:

• 16 Independent Channels: The breakout board features 16 separate output channels, enabling simultaneous control of multiple external components.

• Current Adjustment: Each channel's current output can be easily adjusted from 1mA to 25mA. This range accommodates a variety of devices with different current requirements.

• Single Resistor Control: An innovative design allows users to set the current limit for all 16 channels using just one resistor. This simplifies the hardware setup.

• Expandable: The breakout board is designed to be expandable, allowing users to stack multiple boards together for an even higher number of controllable channels. This scalability is ideal for larger projects requiring numerous outputs.

• Arduino Library: A user-friendly Arduino library is provided, enabling seamless integration and control of the breakout board's features. The library abstracts the underlying complexity, making it easy for developers to focus on their application logic.

Tools necessary for use the breakout Board

Solder iron. Pin header male (8 Positions). Pin header male (16 Positions). It is recommended use a breadboard for solder the pin header connector to the breakout board, solder the pin consistency, use this method for all pines.

Connection & Setup

Adjusting the output current of the sixteen outputs, before to continue we need to set the output current, connect a resistor between the pin R on the board. The magnitude of current (as a function of Rext) is around 20mA at 930Ω and 10mA at 1860Ω (please see reference datasheet for MBI5124 IC).
