1A continuous current per channel (2A peak).It can also drive bipolar stepper motor.Dual Channel Motor driver for DC brushed motor.Or Stepper Motor with 4 leads (bipolar).Which motor is suitable for this motor driver? As long as the motor is: If you power it >20VDC and enable on board 5V regulator, it will get quite warm and it is normal. The board there are build in flyback/back EMF diodes too. Maximum current output is up to 2A(peak) per motor. Lithium Ion Rechargeable Battery and ChargerĬompatible with Arduino, CT-UNO, Maker-UNO, Raspberry Pi, and many more controller board as it is based on TTL logic (0 to 5V).Lead Acid Rechargeable Battery and Charger.If using this material on another site, please provide a link back to my site.

This completes our introduction to the L298N dual full bridge driver. This is in my opinion the smart way to go to save time, money, and effort. This included power connectors, diodes, LED indicators, and even a 5-volt regulator. Shown above is a pre-assembled board I bought off Ebay for $8 with shipping. ENA and ENB can be connected directly together to enable both channels at once or simply tied to +5 volts and both channels making all four outputs active at all times.Ī 5-volt TTL level input to In1, In2 In3, or In4 will produce a corresponding output of Vm (motor voltage) minus about a volt. ENA will turn on A1 and A2 when with a digital HIGH (5-volts) and off when LOW (0 volts) the corresponding outputs will be floating when off. The current sense pins in general can be tied to ground, but one can insert low value resistor, whose voltage reading is proportional to current.ĮNA, ENB, and In1-In4 are all standard 5-volt TTL logic making connection to most micro-controllers easy. The four power amplifiers and grouped in pairs of two with individual enable pins (ENA, ENB) and individual current sense pins (CSA, CSB) for each pair. Perhaps an updated version will include these internally.
I have used more common 1N4001 rectifier diodes and they seem to work fine. One of the annoying features of the unit is the lack of internal parasitic (flywheel) diodes to deal with voltage spikes. Pictured above is the basic L298N circuit used to drive inductive/magnetic loads.
