Low cost, public domain, stepper analyzer - season 2.

PCR

PCBs are here,

i can supply the pcb, the two sensors and the eprom.
due too some family buisness i do not know if i can solder them in the next weeks. So selling the parts only would be the best for me. Best

No problem to sold them myself.
How do we proceed to pay you?

PCR

Contact me via PM

PCR

So for the price.

5 € the pcb
2,5€ for the sensors and eprom
1€ for 40 pin connector
1€ for resistors

due to a mistake at digikey the capacitors are to small.. So these have to be self sourced ( easy)

shipping with tracking 8€ without 4€ in europe
germany 3 € shipping

Hi @PCR, did you manage to get it working? Any problems with the design?

arhi

where are you purchasing acs70331 ?! comet don't hold them, jlc don't have them, mouser offer only dev boards, digikey nothing on stock for ages and min order q is 6000 .. I was looking to get them for another project but ..

PCR

@arhi orderd them at digikey.

Best

@arhi , this is the digikey part I used https://www.digikey.com/en/products/detail/allegro-microsystems/ACS70331EESATR-2P5B3/8120682

@PCR do you still have spare boards and parts?

Egon.Net

@zapta I really love your project! Just what I was looking for!

arhi

@PCR what part? QFN also or?
@zapta that's QFN I need soic and taht's 2.5A I need 5A ..

I'll probably go then with 5A regular HAL ACS712 .. it's not fancy GMR but regular HAL but at least I can get it easily .... I hoped I can easily get GMR version in soic8 package but..

tenaja

@zapta I'd like to get one of your boards, if you still have one. I sent a private chat message.

zapta

@tenaja, don't have spare boards left but I can make a few for shipping in the US if there is a demand. It will be at cost, and you will need to order the TFT display from buydisplay.com yourself.

PCR

Still have Boards. Will answer all PM today. Stressfull weeks... Sorry

tenaja

@PCR I will take one! (If you can ship to USA.)

SOIC is definitely easier to solder and I would love to find one.

I modified the QFN footprints on the board be easier to hand solder, having longer pads, somewhat similar to the Schmartboard boards.
