Connector pins bent on arrival
#ubitx-help
Goodmorning dear OM's and builders of the uBitX transceiver,
?
I recently bought the uBitX and looking at the components I noticed that some pins of the Raduino board are bent. I do not know if that has been done for a reason or just by accident. I would get confirmation that these bent pins needs to be bent or to be adjusted before putting the radio together. I can imagine that all should be placed in the connector on the main board. The pins are bent in a way that they could never fit in the connector.
The bent pins are those on the lefthand side when you look from the front of the radio. The picture below shows how i received the board. I guess it needs to be corrected but perhaps someone can help me. |
Very simple. take a mini? nose plier or tweezer. Apply the tool on these two pins and covering few normal pins and? try bending the. And? they restore. On Thu, Dec 20, 2018 at 2:07 PM <pa1cjt@...> wrote: Goodmorning dear OM's and builders of the uBitX transceiver, |
here is a picture - of course out of focus On Thu, Dec 20, 2018 at 2:20 PM MVS Sarma via Groups.Io <mvssarma=[email protected]> wrote:

Looking over the "MBITX - WIRE UP" page from HF Signals, the last 2 pins toward the top of the picture are: Top pin - no connection 2nd from top -?+12v to the Raduino board (I assume the one pictured) Did you get this new from HF Signals, or used from somewhere? The short answer to your question is that the pins do need to be straightened and connected to the analog (main?) board, otherwise the Raduino will not have any power to run.? The option is to wire up a separate source of power for the Raduino, using the 2nd pin and a ground, or power through the nano USB port If the rig was used before, there may have been a mod to power the Raduino separately by bending this pin away from the connector and attaching another source of 7 to 12 vdc, or through the USB port on the nano.? This is done if you want to run the rest of the rig at higher voltage.? The voltage regulator on the Raduino is already marginal (in my opinion) from a power dissipation standpoint at 12 v dc. raising that voltage makes it worse.? Using a separate supply avoids that problem. 73 Evan AC9TU |
Before restoring the pin to mate with the socket, we should try to find out how the pin was bent.? Was this on purpose or by accident?? If by accident, then correct and insert.? If on purpose, why was it bent? This goes back to my prior question on how the board was acquired.? If new, then straighten, if used, is there any history that could help determine why the supply was removed from the Raduino board.

My curiosity is why it was mounted this way.? It requires that you purchase nano replacements without the headers soldered in place, as they are upside down from "normal" installation.? It also restricts access to the reset button on the nano (might allow for fewer power off reset requirements).? My only guess is some where between "shielding" and board trace routing.
Just curious, not a criticism. Evan AC9TU |
Evan, ?we don't have to become Jamesbond, on this issue, normalize and use them.

I have also received boards like this and all I did was use a smooth jaw

bend back the pin to right angle and plug it in. Thats it! Raj At 20/12/2018, you wrote: Goodmorning dear OM's and builders of the uBitX transceiver, |
Older versions had the NANO mounted on the front of the board, soldered in place - If they put a socket on the front, the NANO would stick out too far and and short against the back of the display which was plugged into the front of the Raduino. ? They started putting the NANO in a socket on the back side of the Raduino which required the pins to be soldered on the NANO differently. ?No problems with the display shorting out and maybe destroying either the display OR the NANO - it happened more than once with the old way of mounting.

Hi all, it was received in this way by HF signals so I guess it was damaged by mistake. As reading all the comments it is pretty shure that it was accidentally so I will bent them back to their original position.
I thank all of you for the help given and wish you all merry Christmas and a good and healthy 2019 Best regards, Kees PA1CJT |

Thank-you for filling me in on the history.? It makes perfect sense that they would not want to redesign the Raduino board when a simple change solves the issue. All, Apologize to the group for expressing my curiosity in a thread that was focused on a related, but different issue.? Will keep my curiosity in check in the future. 73 Evan AC9TU |
?I suggest using needle nose pliers, smaller ones if you have them, or a medium hemostat. ?I always bend carefully, a bit at a time and check, then a bit more as required. ?Regarding hemostats, I have been using them for decades. ?Handy items. Work as heat sinks when soldering some leads in place. ?Wayne WA2YNE |
