MIKROE-1526

2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 DC MOTOR click 2 3 4. Essential features 1. Introduction DC MOTOR click with its DRV8833RTY ICs is limited to a 0.9A driving current with 0.22 current sense resistor. The 74HC4053 IC is incorporated into the design in order to run the motor with only one PWM line available on the mikroBUS Turn the board upside down so that Turn the board upward again. Make sure socket. Use jumper J2 to select whether you the bottom side is facing you upwards. to align the headers so that they are want to power the board with the on-board Place shorter pins of the header into the perpendicular to the board, then solder the or external power supply connected to the appropriate soldering pads. pins carefully. CN2 screw terminal. The motor should be connected to the CN1 screw terminal. DC MOTOR click is a DC motor driver board in mikroBUS form factor. It features the 3. Plugging the board in DRV8833RTY H-Bridge motor driver, click 74HC4053 multiplexer and two screw Once you have soldered the headers your terminals. DC MOTOR click communicates board is ready to be placed into the desired BOARD with the target board via SELECT1, mikroBUS socket. Make sure to align the www.mikroe.com SELECT2 and nSLEEP control lines, PWM cut in the lower-right part of the board input line and nFAULT feedback line. The with the markings on the silkscreen at the DC Motor click Manual board is designed to use 3.3V or 5V power mikroBUS socket. If all the pins are aligned ver. 1.01 supplies.
