We finished 2020 at the last minute with 2^8 backers! I would like to thank everyone once again for their support, understanding and patience. The real challenge is just ahead of us: 2021 in which we should somehow get 2^10 sales to survive. We'll see if this time the mission impossible will be really impossible (maybe it's time to invite some Tom Cruise into the game). I wish you all the best in the New Year, to endure what is yet to happen.

Does someone know what's up with shipping? My order was supposed to be shipped on December 11, but is still being processed. I contacted the creator via the form on Crowdsupply on Monday, didn't get an answer.
There's no update about shipping delays, no email notification, nothing. Did anyone receive their order that was placed after the first (original backer) Units were shipped?

Hi Moragor, unfortunately I have not control over shipping process, but I was opened a new issue in their internal tracker instantly, but didn't see any action so far. As many already learned in one or another way is that everything with CS takes time (actually ages if comparison with other companies in so-called digital age). Why is that I don't know, perhaps lack of resources. Regarding estimated Dec, 11th shipping date: a new batch arrived on the US soil at Dec, 3rd and due to lack of response from CS (or Mouser), DHL finalize delivery at Dec, 18th. But, that shipment is still not officially entered Mouser warehouse, at least didn't two days ago!!! One thing is for sure, when it become available in Mouser warehouse system, you can expect delivery within 2-3 days.

@prasimix - I did receive my unit - thank you!

There was a couple of small issues I noticed during assembly though.

Firstly - for one of the modules, there is a capacitors missing from the top-right corner:





I assume it was damaged in handling or in shipping?

And secondly, for the protective earth cable - one of the terminal ends was missing:



Finally - the earth connector on the AC board is slightly bent - but I assume that's not a big deal?



Do you know how to sort out the faulty module or earth cable though?

Hi, the elco on the dcp405 module definitely fell off during transport. This is not the first reported case: this is Bolek & Lolek quality :(. Please just solder it back.

The Earth cable requires the addition of a Quick Disconnects 4.8 mm terminal. If you can't do it yourself send me the shipping address to PM and I'll send you a new cable.

Hi Prasimix,

OK, let me see if I can solder it back carefully. Sorry to hear it's not the first reported case  |O

I will let you know how it goes.

If the capacitor was also damaged (beyond just being knocked off), there's no risk to the rest of the unit, right?

Let me see if I can find that missing terminal locally - otherwise I may need you to send a replacement.

For now, if I don't connect that terminal to the second module - is it a major issue?

Finally, I was able to update firmware from version 1.0 (what it shipped with) to version 1.5 (latest on Github).

I do note the boot0 switch is a little tricky to press - I actually had to take off the top cover, and watch as I pushed the pin in

I also tried to use EEZ Studio to update the module firmware from my macOS machine.

However, it didn't give me an option to update the firmware, and it lists the firmware as version "0.0".



Is that normal? Or is there some way to update the DP405 firmware?

Right, just don't source more then e.g. 3 A

No

I'd like to suggest usage of DMM probe tip, no need to remove top cover :)

Ok, I got the point: 0.0 looks confusing, we'll remove numbering for module that doesn't have an on-board MCU (as DCP), therefore no firmware is available for it. I'll report that on GitHub.

Misleading info about firmware version for DCP module is reported as #96.

@prasimix - OK, I tried resoldering the capacitor back onto the faulty board. However, the capacitance measured appears completely different to the other (working) board.

Is there some way I can simply send back the faulty board to replace with an intact board, considering it arrived to me damaged?

How did you measured capacitance by removing them from both boards? If they are connected with the rest of the circuit you can expect anything but accurate measurement. Still, you can send me back that module if you consider it faulty and doesn't work as expected (i.e. cannot deliver all 5 A).

Today we finished a series of EMC tests. It remains to pass safety testing according to EN 61010-1. Keep your finger crossed!
