Description

OVERVIEW

The L293D module is a compact motor driver module with two full bridge circuits and individual enable inputs. Each channel can continuously drive up to 600mA and can tolerate up to 1.2A non-repetitive load current. The module accepts 5V up to 20V motor (or other inductive load) voltage. It also has a built-in 5V regulator for the logic circuit that accepts up to 12V input power sourced from either an external power or from the motor power source. This is selected via an on-board micro jumper. Aside from the obvious benefit, the internal regulator may be advantageous in applications without a microcontroller as it readily makes the module useable with just the input signals added. Two additional micro jumpers allows each channel to be permanently enabled or controlled by the host.

The inputs are accessible from standard 2.54mm pin headers and outputs are conveniently derived from screw-in terminal blocks.

The L293D module is part of Layad Circuits’ Kimat series of rapid-prototyping products.
