I have, breakout boards have been the bane of my life.
Old desktop computer on the router died over the weekend, grabbed a 'new' Pc from up in the hayloft, got a stack up there all bagged and clean genuine install of XP on it.

Got it all setup, nice HP Compact and wouldn't work the router, router was working fine on Friday. Threw it to one side and grabbed a Trusty Dell SX270,used loads of these over the years, absolutely bomb proof.

Still dead.

Go looking in the router box, no charge pump light. Check the output from the Dell with a scope, 4.5 volts dead steady at 17kh.

Short enable down to ground to bypass the charge pump and voilà, all working. only problem is if the router is on whilst it's booting up it jumps all over and the spindle starts and stops on it's own 3 times.

This is about the sixth time I have had different breakout board with charge pump problems. So basically 4 hours wasted because someone who is supposed to know better when they are designing can't be arsed on checking properly.

When you query problems all you get is "Well I have sold loads of these and not had problems "

In the past I have sent 5 boards back that didn't work correctly and they got returned with link wires and extra diodes soldered on over the back and an input stolen so it could amplify the charge pump.
If they are that good why the mods ?
