Prós: Produto de excelente qualidade e ótimo custo benefício. Contras: O envio atrasou demasiadamente, mais culpa do serviço de entregas brasileiro. Recomendo a compra.

no cons. Great build quality, fast delivery. Item works as expected. Would recommend!

A parte i tempi di consegna molto lunghi(20 giorni lav.) ho ricevuto i 3 driver che avevo ordinato, a prima vista noto dei particolari che mi hanno subito deluso "l'integrato A3967 saldato storto!!", i piedini del cip sembravano appena appoggiati(vedere foto)ha funzionato x 2 minuti dopo di che e... A parte i tempi di consegna molto lunghi(20 giorni lav.) ho ricevuto i 3 driver che avevo ordinato, a prima vista noto dei particolari che mi hanno subito deluso "l'integrato A3967 saldato storto!!", i piedini del cip sembravano appena appoggiati(vedere foto)ha funzionato x 2 minuti dopo di che e morto!.Dopo aver segnalato il problema, hanno riscontrato l'evidenza e mi hanno rispedito un'altro componente, peccato però che avevo segnalato la scarsa qualità di tutti e 3 i componenti da me ordinati e me ne hanno sostituito solo uno. Adesso mi ritrovo con uno buono e 2 che lavorano a modo loro...Se non dovessero più funzionare gli altri 2 sarò costretto ad acquistarli altrove. Read more

Dealextreme you r Great thanks for all

Works like a charm! I use them to make a small 2d printer and are put to the test at maximum speed for a long time. No defaults. Did't noticed any cons yet.

This looks to be the original EasyDriver V4.4 Stepper. That's probably the reason why the price is steeper. I like the fact that it comes without header pins unsoldered – that way I can adapt it to my project. Based on the Allegro A3967 controller. Microstepping, sleep mode, all-in-one package is... This looks to be the original EasyDriver V4.4 Stepper. That's probably the reason why the price is steeper. I like the fact that it comes without header pins unsoldered – that way I can adapt it to my project. Based on the Allegro A3967 controller. Microstepping, sleep mode, all-in-one package for bipolar motors. This is more of the design of the EasyDriver board itself, but the pinouts for the stepper motors are not spaced for screw terminals, but plain 0.1" headers. Something to bear in mind when hooking up your steppers. Would have been good if it came supplied with a suitably-sized heatsink, I used SKU: 35816 and had to cut it down to size with a rotary tool. You will need to heatsink this guy to get any useful output on your steppers. Works very well with Arduino and other microcontrollers. This is a cheaper version to the newer BigEasy driver. Specifications of this board can be found here: http://www.schmalzhaus.com/EasyDriver/index.html If you're tired of the limitations of the L298N or ULN2003-based steppers, try these out. Way better control and microstepping functionality awaits. Read more

It is very easy to use, on the internet you can find a lot of tutorials how to use it with breakout board or arduino. Not designed for big projects, gets really hot after few minutes of work. It would be better if there are also headers soldered to the board. More about this driver you can find on http://www.schmalzhaus.com/EasyDriver/index.html Good driver for small hoby projects, worth of buying. Read more
