Ok now the updates for the V4 have been released, anybody wanna get rid of their (working) EZb V3s? I'm gonna need a few for my projects, and since the V4 is not readily available yet...
Send me an email and offer:

Thanks!
contact me at alan@thetechguru.net with a reasonable offer.

Just plugged in the V3 you sent me, it doesn't work. You said there was no problem with it.
The bluetooth module light blinks red, like it should be, but the rest of the board is dead.
Since he gave me a great price its no big deal, I may just change what components needed changing but is this a chip issue?
Like I said there seems to be power coming in, as the bluetooth module seems to be responding but there is no blinking blue LED. I haven't checked if there is power anywhere else in the board. I powered it with 5v all the way to 9v.
Any help will be appreciated.
A list of component part numbers would help too. It should help to mention that I have a working V3 Ive been using for months now so it's not a "User" fault haha.
Thanks.
There are quite a few posts recently about the best ways to go about checking each component on the EZ-B too. The most common issue is the regulators, there are two so it may be that the one which powers the BT module is OK but the other one is gone.
If it is a chip issue EZ-Robots can probably sort it out for you but first try to make sure it is the chip before going down that route.
To add, if there is an issue which needs discussing with the seller then it's probably best all around to keep that discussion private via email rather than air dirty laundry on the forum
Like I said no issue with the seller...I like tinkering anyway and since he gave me a great price...that's why I thought it was ok to post it in public.
I'll do the diagnostics, thank you again Rich!
Diagnostics may help however generally covers connection of RX and Tx from chip to bt module. You may be better off starting with checking the voltage at each regulator.
Also, it may pay to remove the BT module, remove the chip, resit the chip and then resit the bt module. It may have come loose during transit.
just a idea , unplug the blue tooth and remove the Pic , clean the pins and reinsert the chip. Sometimes they just need to be reset. let us know if that helps bud.
edit - apparently Rich had already suggested that , I must have missed it. I have just been slammed busy at work. Retail plus holidays equals loosing your mind lol.
Let me take this opportunity to wish everyone on this board happy holidays! stay safe!
thanks guys!

Oh yeah man I was planning on getting more than one V3...I'm using them on other projects too.
I'm also assuming people will sell when they actually get their V4s on hand...
