        If you have any questions or need a helping hand with your MOTHERBOARD kit, this is the place to be.

        Post your question here and either I or someone in the community will help you out.

          on the motherboard manual page 15 “Circuit – IO LEDs (Optional)” you mention a video to help in assembly. could you provide the link for this video please.

            The manual states on page 20 verbally, and shows pictures of r1 and r2 as 1k resisters, but the BOM states 2k and the kit comes with 2k resisters. Which is correct?

              TBH, soldering the USB power port was impossible for a 69 year old with hand tremors. I Opted to use an old cord and hard wired it.

              FWIW, the manual on page 11 under USB Power state, “you can snip an old USB cable and connect the red and wire wires to the terminal block’s VCC In and GND.” Might wanna fix this.

                  Hi Udenk,

                  The USB socket is a difficult component for sure. My 36-year-old friend with a shaky hand couldn’t manage it. I’ve messed up a few and I have pretty steady hands. I hope the wired method of powering the board is convenient enough. I’ve fixed the error you pointed out, thanks for that!

                  Regards,

                  Martyn

                  I had to order a new motherboard to solder. The usb thing was a mess and I totally screwed up the traces. I was able to check things with a meter and verify that it is toast. The positive connection there now connects to ground. Next time Im going to do a different way. I also bought a different solder iron as the one I had was not working like I thought. I also found some thinner solder and I will try that as well.

                  Maybe the second time it can work. When I find the one I trashed I will post where it went wrong. I had to take a break as I was so mad for messing it up.

                      Oh dear, sorry to hear that. The USB can be tricky. I’ll get a video of me doing it released before your new Motherboard arrives. I think we can salvage the other one and just use the terminal blocks for power. If you find it, post a picture and we can get it sorted. A thinner tip and thinner solder will definitely help. I also find a magnifying glass with a light on helps tons too. Something like this: https://www.ebay.com/itm/373863355011?hash=item570bfe1283:g:Mt8AAOSwRaFh29Rb

                          Well butter my biscuits. Thank you for your advice. I re-read the manual from the beginning and found that I missed the “make sure the jumper pads are soldered together” line under power test. I then powered up using a power supply and I got a blue light.

                          WHOOOO HOOOO.

                          I then put the IC in and I got more blinky blinky. Now on to the next one. Thanks

                              Great news! Sorry I didn’t get to your post before sending the new kit out. At least with 2 Motherboards, you can build 2 devices, and maybe even have them communicate with each other over Bluetooth.

                              For that, you will need a couple of these: https://www.ebay.com/itm/224313035719?hash=item343a194bc7:g:oYkAAOSw5dNWqqeA (HC-05 Bluetooth module).

                              I will get around to posting some Bluetooth code examples soon, but the internet has plenty of guides in the meantime.

                              Happy Making!

                                Do you have a tracking number? I havent seen the second motherboard show up yet

                                  It should be in your inbox. Maybe your spam folder? Your package has just arrived in the US sorting centre. I will email you the link.

                              What gauge wire were you using. I tried to search for gauge and ga in the motherboard manual but didnt find it. thank you

                                  I use 20AWG. 18 is useable but 20 is easier. Thanks, I’ll stick that in the manuals and in the 3D printing post for others.

                                      I bought 20AWG and it still leaves at least 1-2 wires I cant get into the screw terminal. The terminals dont seem to open up enough.

                                      Just an observation. Not a complaint. I am looking forward to the next set
