#MOTOR ARDUINO DRIVERS#
For example, the current feedback from the two MC33926 drivers is connected directly to some of the analog pins on the MKR1000. When plugging the MKR1000 and the Motor Carrier, some of the pins will stop being available for you to use in your code, as they will be needed to control some of the features of the Carrier. Note that for extended use or high-current motors, an extra heatsink (and eventually a fan) might be required for the drivers. There is an interrupt line connecting the SAMD11 (on PA27) and the MKR board. The SAMD11 is also used to control the servos, read the encoders, and read the battery voltage. In addition, there are two DRV8871 drivers that are controlled from a SAMD11 microcontroller that communicates with the MKR1000 via I2C (SPI optional). The MKR Motor Carrier features two MC33926 motor drivers for high-performance DC motor control with direct connection to the MKR1000, current feedback, and capacity for up to 5 Amps (peak). Terminal block and 3 pin/4 pin header connector Over Temperature shutdown protection (for DC motor drivers) 5 Amps Peak, RMS current depending on the degree of heat sink providedģ Amps peak, current limited by current sense resistor.
