So, I took a gamble and replaced the already good Regulators. The EZB still doesn't work. All of the voltages are there. D1 has opened up and doesn't show any transistor or resistive, or capacitive readings, just completely OPEN. I need to know the value so I can replace it as a last shot at this. I have believed it was the cpu from the beginning. They used to sell those in the store for $15 , I think. Now, I have found this diode open.
So, does anyone know the value? I am guessing 5v Zenier?
Upgrade to ARC Pro
Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!
Got any ideas if I have voltages and everything looks good. The Regulators have been change and the bluetooth hooks up but no ports on cpu work.
Thanks for the Freebie !
You can use basic leds (except red those are low voltage) to test them , doing it this way is safer that trying to hold multimeter probes on pins and accidentally slipping and shorting something out.
P.S. It is also bad that we cannot give credit to more than one person. Many times many people are helpful.
I have offered this to two other users who haven't taken me up on it. If you get to the point you just want to replace your EZ-B, I just ordered a V4 leaving me with a spare V3 board I don't need and would be willing to sell for what I paid for it plus shipping (which would be ~$5 for USPS delivery).
Contact me at firstname.lastname@example.org if you get to that point.
Thanks to Everyone!
My offer stands if it flakes out on you again.
