Pico Eurocard Rev 2.0 - Free (just pay shipping)

shabaz
shabaz over 2 years ago

EDIT: all gone, but it is easy to build your own, using the more recent (currently rev 2.2) files on GitHub.

(Hoping it is OK to post this, since it's a not-for-profit thing!).

Hi,

I have three Pico Eurocard Rev 2.0 (it's a recent version, with no known issues so far!) build-as-you-go-and-bring-your-own-Pico package : )

A fully populated Rev 2 looks like this:

image

However the build-as-you-go-and-bring-your-own-Pico version requires you to bring your own Picos', and it can be immediately used, but it is missing stuff that can be added later, such as the voltage regulator modules and microSD card socket. 

The board has all surface-mount Rs, Cs and the single MOSFET pre-soldered, since they would be a pain to ship unassembled, due to the small size.

The package includes a bag of through-hole parts, but it doesn't include header pins/sockets and DC-DC converter, DC jack and microSD socket. Those are all easy to locally source, and are not essential, to use; just a Pi Pico is required, but you may wish to also get some header pins as well. Then, if you need (say) more 3.3V capability, then you could buy a 3.3V regulator (it's just a couple of £) and add it on.

These are spare boards, I don't want to charge anything for them. If you feel uncomfortable with that, then I'll accept the cost of the raw PCB and components, which let's say is £5. But I will only accept that so people don't feel uncomfortable accepting a free item : ) but there's no obligation to pay - just pay for the shipping. I will have to declare the nominal £5+shipping on the customs form however.

There's no warranty, and no returns since this wouldn't be a very good business venture to sell at no profit : ) and it's an experimental board and I'm not charging or warranting the SMD assembly either : ) However as mentioned, it's unlikely there will be any fault (and I took ESD precautions soldering the SMD parts).

The photo here shows everything that is included.

This is the contents of the bag of through-hole bits:

Tracked shipping (from UK) will be £15 USA, £10 in Europe, and let's say £5 UK, and I will use parcel2go.com.

Example, USA shipping:

Please use the parcel2go.com website to see the quote for any other country (courier collection, tracked please!).

If you're interested, please leave a comment telling me, and then send me a private message with the shipping address (or click to connect and then send me the shipping address). There are only three boards as mentioned (one per person), and I'm unlikely to build more by hand : ) 

In terms of payment, I have no convenient mechanism for this that I wish to use, but instead we could barter for say coffee vouchers : ) for instance costa e-gift using https://gifting.costa.co.uk/
I'll send you my e-mail address for that.

    The USPS tracking info is "Your item is being processed by United States Customs." on one of the packages, and the other is "Your item has been processed through our facility in ISC CHICAGO IL (USPS) at 8:11 pm on November 20, 2022." but I don't understand why there's no additional update since the 20th. I'll give them a call tomorrow (Monday) in case I can get any detail.

    The status finally changed today, after a week remaining static. 

    Both packages, at the precise same time, are now cleared it seems. Still no idea when it will get there, but this is progress I guess!

    Update, I received my Pico-Eurocard! Thank you again Shabaz!!

    I am still waiting for a replacement Xiao (I thought I ordered a new one... I did not!)

    But in the meantime, I loaded CircuitPython and made some blinky happen.

    I plan to do some exploration with FreeRTOS very soon. I'm looking forward to using the Dev Board while I do that.

    Thanks again! You did a great job on the board. And I really appreciate the effort of including printed instructions!

    Great! I did some FreeRTOS projects with this combination. Check the FreeRTO SMP release for the Pico. It allows you to use both ARM cores in a graspable way.

    Also, which LED resistor is connected to the Power LED? I need to increase its value... Slight smile

    I have your posts bookmarked! You started posting them right around the time I first considered it.

    My first project need is a bit of overkill for FreeRTOS. (Inbound Telnet server.) But, I think it'll be a good starting point and it is something I need.

    Hehe nice alternating blinky demo. It's like a level crossing : )

    Glad it arrived and is functioning! Thanks again for the coffee vouchers.

    It's not connected to a GPIO. How are you powering the board? My LED is bright.

    GrinningThat does look a bit bright!

    It's R6 as Jan mentions. It's a very low current LED, I wasn't too sure what resistor value to use at the time, but clearly the resistance wasn't high enough!

    I can't recall, I think I use a 680 ohm resistor there (although the schematic says 100 ohm). So you may wish to try (say) 2.2k ohm, since perhaps even 1k might be too low.
