Description

The module is based on a Texas Instruments DRV8835 is a dual driver siników DC. The advantages of the system are extremely small size - tile size case DIP 14-pin. The module can control the motors with a supply voltage range from 2.0 V to 11 V with a continuous current consumption to 1.2 V. the control Channels can be combined to improve the efficiency of current load - up to 2.4 A. the Kit includes module and connector goldpin.

 

Connection

For proper operation of the module, you need to bring food logical units between pins VCC and GND, the power supply for the motor VIN and GND and connect insights, responsible for the movement of the engine, which is described in the table below. The output MODE associated with the high position, the mode is PHASE/ENABLE, see description in the next section.

Modes of operation

The driver can operate in two modes: the primary PHASE/ENABLE , and advanced IN/IN. The selection is made using the output MODE. The differences between modes are given in the tables below.
