SmartElex wireless Remote control L293D Motor driver.
We know that hobbyists are willing to build the wireless remote control
robotic vehicle. Mostly hobby people faced the complexitywith various
factors like Operating Range, Accuracy, signal switching issues & mainly
those are expensive. To solve these we are introducing Our SmartElex
Wireless Remote control L293D motor driver under “SmartElex” Brand at very
low cost.
The SmartElex Wireless control L293D Motor Driver is designed to make
connecting motors and drive to your Robot as fast and easy as possible. The
heart of the Wireless Motor Driver is the NRF24 Trans receiver which allows
the board to control 4 BO motors at once, both CW and CCW, and to brake
electronically. The L293D H-Bridge is rated up to 1A per channel at 12V, which
means it will drive a fair variety of hobby motors ranging in power.
