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

[zapta]

@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.

In SOIC parts, ACS724LLCTR-05AB-T is very good, much better than ACS712 in our experience. We use them in our latest automated test equipment.
