Is the Waveshare Core2350B0 suitable for a budget/test Pico Computer 3, considering the PSRAM pin configuration?

Bryan, I will take one please - pm me with payment requirements.
Doug.

G'day Bryan,
Cheers mate, I will happily put my name on 1.

Had meant to ask you if you wanted one if Grogster was doing a batch but you have beaten me to it.

Let me know payment details etc.

Going to be busy next few days, will keep an eye on here though  

Regards, Lyle.

Well guy's thinking about it I will only need one of these boards so there is one left for a member  

Regards Bryan

If anyone else in Canada is interested, one more will be available. Cost is going to be about C$50 plus Canada Post shipping.

Is that one still available, please? I'm in Toronto.

Yes They're through customs now. That will account for all of them.

The boards arrived. JLC did not have the RM2 wifi module or the PSRAM, so those are missing. I soldered PSRAM on the two I want to keep, and it is recognized.

I've PMed the three people in Canada who expressed interest. I'm ordering the Wifi part from Digikey.ca. and can order extra. In my PM, I misspoke--the RM2 Wifi part is $4, not $7.

Shipping was stiff: $50USD and then $43CAD at customs (including Canadian tax and FedEx's handling fee).

Looking sweet.

Ok, boards ordered. Shipping was stiff: C$75 (saying I'm in a "remote area"). There may be customs duty.

If anyone else in Canada is interested, one more will be available. Cost is going to be about C$50 plus Canada Post shipping.

okwatts--yes, I'll include the RPZ baseboard and all addon PCBs--gratis.

I have sent you a DM. I need to pay you for the board  

Hi Lizby
PM sent, looking forward to this.

Leo--I didn't get your DM (PM). Please send again or let me know here whether you want me to order the radio module and/or PSRAM. Then I'll figure out about shipping.

Scruss--also wondering if you want radio module and/or PSRAM.

dxf files for the end-plates are unchanged from the reference board

I've succeeded in flashing 4 of the 5 boards, but for the 5th one, a drive doesn't come up. As with the others, "Disable" toggle is down, power button is off (out), boot is pressed. I've tried a different micro-USB cable. I've tried over a dozen times with 3 different USB ports on my laptop.

Any suggestions as to what to try?

Sorry folks - a bit late to the party on this one.

Been very busy the last few weeks at work, and simply no time to play with the latest offering.  

I know Bryan has already ordered some boards, but I will be ordering five.
I will also be looking at doing some gerbers for the front/rear panels.
This won't happen overnight, as I am still quite busy, but I can at least get some boards ordered.

Is there an alternative source for the SDRAM chip, if I need to manually fit these if JLC are still out of stock on them?

I also had to change the 10k 0402 resistors - JLC said they had no stock.
I just followed my nose, and used their parts selector, to choose another 10k 0402 resistor that they DID have plenty of.



JLC also moaned VERY SPECIFICALLY about the design NOT using the approved 2350 oscillator design - Peter: care to comment?



I just ordered anyway, as I expect your design is fine in that area, but obviously some custom designs that DON'T use the RP recommended oscillator design have caused problems for some people, or JLC would not throw up that pop-up.

Well I just looked at my bank account and that figure I put p before was way off the price  

So each board will be $75 each with shipping so guy's that have said they want one please confirm whether you still want one.

Regards Bryan

G'day Bryan,
Thanks for the update, $75.00 AUD + shipping in AUS sounds about right, I'll still put my name on 1 if that's ok.

PM me with details when you need payment, stick a few bucks on to cover the CNC PCB's as well, I might be using both if all goes to plan  

Regards, Lyle.

Just checked the JLCPCB shipping and looks like the boards will be here this week as they are in transit from Adelaide  

Hello,

if somebody has spare board for sale, or want to order one more I am interested to spare costs for example.
I am from Hungary.

I know it sounds silly but where are GP8 and 9? I'd like to connect a serial device to COM2 but I can't find the pins.

GP8 and GP9 go to a CH340 and this is connected to a USB-C socket. See schematic in first post
