I got the AD5687RBRUZ from Arrow just last week… Unless I bought them all.

#353

Oh you’re right. My brain saw red on the octopart page and just decided it was out of stock as well. Thanks

Yes you can use the -RL7 version as well, it’s just a version on cut tape instead of in a tube… Use the mouser “compare” to see, it works fine I’m using them on my builds.

Getting my Mouser cart finalized and just wanted to note again that the 10k and 1k resistor part numbers are still switched as @reijo pointed out previously. Going to report the issue on github to make sure it gets seen. or if @tehn sees this and can switch it. Cheers!

It then makes the AVR 32 code not work so i can make the folder. Any advice? Been scratching my head at getting AVR 32 on a MAC for 2 days now.

It then ends up with the result of this

            Georges-MBP-2:module George$ make
     CC      ../module/main.o
bash: avr32-gcc: command not found
make: *** [../module/main.o] Error 127

It looks like the AVR toolchain can now be downloaded from here - https://www.microchip.com/mplab/avr-support/avr-and-arm-toolchains-c-compilers , though I can’t see version 3.4.2

I’d suggest trying to either manually complete the steps the Makefile is trying to do, or possibly replace the link in the Makefile ?

thank you!
That still doesn’t seem to work for me i must be doing something wrong.
However i seem to have it up and running in docker , however , whenever i do the command flash in module i get this

root@8774cd6b7082:/target/module# ./flash.sh
./flash.sh: line 1: dfu-programmer: command not found
./flash.sh: line 2: dfu-programmer: command not found
./flash.sh: line 3: dfu-programmer: command not found
root@8774cd6b7082:/target/module#

#359

If you have homebrew installed, run brew install dfu-programmer.

I wouldn’t recommend running inside docker - you’ll have to try and pass through the USB device to the docker container, this stackoverflow post suggests a way, but I’ve never tried it. I suspect trying to do it that way will be a big headache.

I can get that far on my mac. But no AVR 32 on it. What a head melt. not sure what to do :s I downloaded that AVR 32 folder , its in my downloads but i don’t know how to attach that to what im doing in terminal. I am not super experienced

#361

Finally got some pots and knobs from Think to finish this guy up. Black & Red! Super fun build. Used one of @frankchannel’s partially populated boards.

Hi there! Now I’ve finally read through the thread in one sitting. :slight_smile:

I have ordered a partially pre-populated board and panel from Pusherman, and am in the process of compiling a BOM for all the parts that are missing in that version. I am almost done, but still have (at least) two questions:

  1. Is it possible to use M2.5 screws and spacers through the PCB? I guess I could use a reamer to make the holes a bit bigger, but would that damage the 4-layer PCB? How tall would the M2.5 spacer have to be?

  2. The resistor network 774-745C101473JP is out of stock at Mouser. Could this act as a replacement: EXB-A10P473J? The size looks a tad bit different?

Here is my in-progress BOM document: Teletype BOM for prepopulated PCBs from Pusherman 2020-10-15

#363

The link doesn’t work because of google drive permissions.

  1. M2.5 won’t work, it’s a little too big, so I used m2 and that worked fine. I wish m2.5 had worked since I had a lot of those but alas, no dice. Not sure of the size I used because I had an assortment of standoffs and just kind of goosed it until it all fit well. The part listed in the bom uses imperial measurements but I think it’s either 6 or 8mm.

  2. Have you checked digikey?

Sorry for the permissions mistake. The document is now updated and should be viewable and commentable by anyone with the link.

  1. Thank you for that information! Good to know that M2 works! I will try to find suitable M2 screws at Mouser and I would guess 6mm maybe? Since the distance between the panel and the PCB should be 10mm.

  2. My last resort will be Digikey, since ordering from them comes with extra fees in Sweden nowadays, but it’s good to know that I can get hold of it there.

#365

Another question!

  1. After going through the McMaster parts again and converting from imperial to metric, I get the following:

Spacer: 6mm
Top screw: 6mm
Bottom screw: 4mm

But given the height of the panel (1.6 or 2mm), the top screw will barely make it to the bottom spacer. Shouldn’t the top screw be equivalent to 8mm or something?

#366

never ever ream or drill a pcb unless you have inspected the gerbers and know for certain that you will not bridge inner layers, and even then, i generally would pursue any other possible option before considering drilling

Yes, it feels a bit like a wonky caveman approach. :slight_smile: I’m glad that I now know that M2 screws and spacers will work. Just need to find an 8mm top screw at Mouser (I’ve found a 6mm version that is equivalent to that in the McMaster carr mechanical parts BOM, but I can’t see how it will reach the 6mm spacer underneath the OLED).

#368

M2.5 works, if you use nylon screws… they mush through the holes pretty well.

#369

Thank you, good to know! I just saw it in this very neat Norns shield case assembly video by denki_oto.

I’ve got some great assembly tips from someone who had used spacers above and below the OLED PCB. He used 4mm M2 spacers above and 6mm M2 spacers below. And also used a low-profile 20 pin female header that supports regular square pins for the OLED, i.e. 200-SLW12001TS.

#370

problem solved! i had forgot to fully solder the USB… easy mistake! and a pin unsoldered for the main IC.
I did the update flash and boom! its done :slight_smile:

Hi folks , i am going to order up some expander boards for terminal. How many external connections can this version of the board make? 2 or 4?
