I sold all the 23 PCBs to various builders. So expect them
Soon

One suspects that wemight need more than 23 :lol:

This is a great board.

50 more on order. 25 was the biggest batch I was prepared to order on a new design revision before testing .

Ok built my first Rev2, programmed ok, but I can't get it to boot even with Diagrom. Are we using the same firmware as the rev1?

Ah you don’t have the firmware.. 2 ticks

Perfect, that's what I suspected, it works fine now, thanks.

I just realised that the 1.6mm cards have killed another AMP connector for me... Maybe I am doing something wrong or using too much force to push the card in but I can imagine many people will end up having the same issue after a while. No issues with 1.2mm cards... Would there be any issues manufacturing these in 1.2mm?

That’s strange..

I have a real problem with 1.2mm.. the card flaps around and the connections are unreliable. I’ve plugged and unplugged these things over and over for years now and never damaged one of them... and obviously i switch these things around a lot and I’m the most oafish/careless person ever in this regard

The connectors should be springy enough to keep the 1.2mm in place reliably - and I've made all of mine in that form, without issues. What I am wondering about is if that has consequences for the 4 layer board.

I prefer the 1.6mm as they do not flop about and I had lots of connection probs with the 1.2mm ones as they were way too loose.

Never really had problems with AMP connector pins bending back , I looked at the Rev2 board and there is just enough of a bevel to get us by IMHO, I find lining up the board perpendicular/right angled to the connector is really important as if you push upwards with them then there is a good chance of bending pins
