Hi @pastthepoint, I am glad that other people building these boards. Do you remember when you downloaded the gerber files from github and what version number is printed on them? The reason is that at one point I changed the design to allow a usage of the Pico's Programmable IO so I wonder what version you have.

I believe that this is the CL that introduced the new version (MK3)
https://github.com/zapta/simple_stepper_motor_analyzer/commit/bc6e5b5a2bedd1de99014e725a0701d6f68a7b74#diff-ca5a89d660952f0b6ae9894238e524ca0ef82bbc301a53af0931c1be35b1f6eb

ACS70331EOLCTR-2P5B3 was always difficult to find in the US unless if you buy hundreds, or willing to use a smaller QFN package/footprint which is more difficult to solder manually. I order them from Aliexpress.

For the 5A ACS70331EOLCTR-005B3 should fit but never tried it. It will also require a change in the firmware for the new scale (otherwise everything will work but current readings will be 50% of actual).

Let me know if you encounter any issue.

I have some coming from Aliexpress too. I should've ordered more. I also have some screens coming. I have the v1.0's. I'm assuming those are still the current ones?

Thanks Zapta. Your work is awesome!

Hi everybody, 11 units went out today for the people listed below (one each). If you are in the US an dong' get it within 2 weeks or in Europe and don't get it within 3 weeks, please ping me.

You can reimburse me for the out of pocket expenses by sending me an amazon gift card for $39 (US) or $46 (Europe). To do that, log in to your amazon account, navigate to the gift cards section, purchase a gift cart for the applicable amount and send me the gift card # via IM here. If your give card will have a different amount due to exchange rate, should be also OK.

If you have any question, please let me know. If this batch will go well I will make more units. If you want to make unit yourself (even commercially and for profit), I will give you all the help I can for no free.

Edit: here is the list

I went to Amazon and checked about gift cards.

They want an email address to deliver it or a phone number to text it.

How does that work?

They didn't mention anything about a gift card number that I could provide to you.

Thanks.

@zapta Sent in chat! Thanks!

@fcwilt send it to yourself and grab the code.

@fcwilt send it to yourself and grab the code.

If someone other than me used that code could that cause a problem?

I have not done this before.

Frederick

paralepsis

@fcwilt I'm assuming that the code is all that is needed, but maybe the thing to do is to wait for another answer?

Nuramori

@fcwilt Once you "make" an e-gift card, you can then email it to yourself. you get something like this:

All you need to do is copy the code after "Claim Code" and IM it to Zapta. It's a single use only code, and is redeemed by him.

@zapta Gift card code sent via Chat.

Thanks a million for this.

zapta

Hi everybody, when you purchase the gift card, please purchase at amazon.com and not at at local amazon sites. I believe that any amazon account should be able to login to http://amazon.com.

Got mine today, SUPER excited. Amazing Stuff!

@zapta Beautiful!

@zapta

Mine arrived.

Thanks much.

The color of the case doesn't match my eyes but that's OK.

And I cannot find the manual. It wasn't in the box. You do have one don't you?

Seriously though, where do I go to read about using this little gem?

Thanks again.
