I bought a few more uLA81 and one came with the pins squished. I should have contacted the seller, but like an idiot I tried to bend them back only to find out that these pins don't bend... they break.
Thinking this would be a straightforward job, I de-soldered the pins only to then find out that pin headers don't fit into turned pin sockets (which I'd installed on the board) so I had to de-solder those... and I'm not sure what I'm shopping for, in order to replace the pins. Obviously I just need a short strip of pins, that aren't header pins, or something.

Re: uLA81 pin problem
I assume this is what you are looking for:

Available from W-P in different length (of pins) and number of pins.
Seems to fit into IC sockets.

Re: uLA81 pin problem
Thanks. I'll look that up.
The sockets are turned pin, so don't accept square pin headers.

Re: uLA81 pin problem
Turned / round pin "headers" are available from most of the major electronics suppliers. It's just that it takes a bit of finding on their web sites. For example, I have bought some from Rapid and Farnell in the past

Cheers. Got some on order. Wonder if I've wrecked the thing ... oh the joys of not knowing
