  • I am having terrible problems with high currents and Easydriver and already fried two of them (with sparks and smoke coming out of the main IC and the chip getting a huge bump from the “explosion”). both are related to excessive current requirements but I thought EasyDriver limited the max current to 750mA irrespective of motor demands or PSU supply. Does it need any current restrictor and why (since other drivers do not need this)? If it does, any suggestion would be appreciated.

    In both cases, I used 24V 1.6A PSU and motor was either 5 or 24V with around 1.2 amp per winding. They both worked fine without a load but, under a load (as it drew more current - I assume) the Easydriver blew up.

No public wish lists :(
