The EZ-B v3 Bluetooth Robot Controller was introduced in 2011 and discontinued in 2013 with the EZ-B v4. EZ-Builder still supports this device, however documentation to get it connected is difficult to come by.

EZ-B v3 Buy-back program

EZ-Robot has offered a buy-back program for an upgrade to the powerful EZ-B v4. You can find more about it on their post HERE.

EZ-Robot Advantages

EZ-B v3 has been designed as an all in one hardware and software solution for robotics. The circuit board contains a powerful voltage regulator, a Bluetooth antenna module, digital I/O, ADC, servo control, serial ports, TellyMate interface, and more. You can quickly recognize how the EZ-Robot Project was designed for reusable scalability. Build many DIY Robots with a single EZ-B Controller by simply moving the board between projects.

Connection Tutorial

The EZ-B v3 has been discontinued in 2013, but is still supported by the EZ-Builder software. This out-dated connection tutorial is the closet we have to demonstrating how to connect to EZ-Builder.

Wow, are there any of these wonderful classic units still out there in the wild?
Hey Dave, funny you mention that I still have mine and love it, use it with the EZ4 for extra sensor outputs.No added voltage regulators needed .One of the guys on the Forum in Vancouver drove all the way to EZ robot in Calgary,Met DJ and asked to buy an older EZ3,He was telling me it was handed over by DJ and was happy about the great service. So I mentioned I wanted one for an older robot I had and this guy in Vancouver sent me that same EZ3 here in Toronto!
Cool. I can see how the old unit could come in handy for extra ports. The added voltage regulator would be a welcomed bonus if you need a compact 5vdc output source. Can't think of much else I'd want it for. I sent in all the old V3's I had for credit a long time ago. I thought I'd miss them but that's not the case. Glad you are finding use for them though. Retro is in. LOL.
We have 3 or 4 boxes full of V3's from the buy back - they all would tell a good story I'm sure. Good to see so many people enjoying the v4's - they're power houses
