Ez-B V4 Conector Types

I saw in another post a picture of the new EZB V4 board sitting in DJ's hand. It occurred to me that there are few different connectors then was on the EZB V3. notably the main power connector and the white female connectors in the middle of the board. I assume the mail header pins are the ADC & Digital ports and the black female connector is the 12c(Correct?). What are the white female ones and what type connector do I need to attach to them?

I'm waiting for 3 of these V4 boards when they start shipping. I want to be ready to retrofit them into my B9 and take advantage of the new options when they arrive. I want to have what's needed here to attach them and not have to wait weeks again for new parts to arrive.

Thanks! Dave

Upgrade to ARC Pro

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.


Power is a mini dean connector. Not sure about the white things in the middle.


The three smaller white connectors are i2c and the longer centered pin is the camera

The speaker is on the bottom of the board that is pressure fit when installed in the case. Without the case, an external speaker can be connected to the speaker pins.

Ahh! Very nice pics and very impressive. Thanks for the close ups. Looks like you have a work of art here for us.

Looks like you've moved the power connection to the bottom of the board along with the Speaker. I'm a little concerned now about the footprint. Wont this make it a little harder to mount this board to the robot in tight places with control and power cables connecting to top, bottom and one end of the board? If I want to mount it "flat" so the ports are on top, I'll have to somehow route the power cable under the board. If this the case I'll probable end up desoidering that power connection and directly solder the power wiring to the board to save room and decrease the height of the board. I can then add a Molex connector for easy disconnection. Kinda like a piggy tail coming off the EZB.


We have an adapter. It's inly 1 cm distance from the board. If you need, remove the connector and solder directly.

The ezb also slides into any revolution chasis and the plug connects to the power.:) it's quite elegant.

Jeremie says hi! He's the creative genius behind the designs:)

Aww thanks boss....'blush'...wait there's an emoticon for that! blush


Hi Jeremie! Love your work!

I see now why you have the power connector on the bottom. This design lets you just "plug" it into your robot. "Elegant" is perfect word for what you've done here.

It's good that you have a adaptor for attaching the power other then a direct "plug in". I have no problem modifying things like rerouting the power connection. I had to do this in the top "brain" of my B9. Very little room up there where my 3rd EZB sits and controls light, motor and power off functions. See the pics below and you can see why I'm looking forward to getting and installing the new, smaller EZB (also I'm looking forward to the WiFi upgrade. I'm having disconnect problems with Bluetooth):

Again, thanks for the preview! Nice work! Dave


@Technopro. I'm camping with you. Very hard to be patient.

Awesome info guys. Thanks for all of the details and pictures of the V4.


I noticed a side connection on the ezb. Like on the border or edge ....its 4 pins, what's it for? User-inserted image


Is that the UART connection?


UART Connector is on the WiFi shield above, that header sticking out is the programming header for our development, it won't be there for the production model. Actually there will be an extra 3.3V and Gnd breakouts there if you guys need it. Hope that helps:)


That's the programming port for us - it won't be there on the production versions. The UART is on the I/O shield at the lower right. In that pic, it has a Bluetooth module plugged into it


Ah I see it now. Thank you.


It would be nice if we could plug in the main power there.


The programming port doesn't provide power to the ezb. You need to power the ezb by the power terminals on the bottom. If you're worried about height, simply desolder the din connector and replace it with direct wires or angled pins like the programmer pins.

You can use a soldering iron to desolder something. Usually a solder wick makes it easier, or a desolder hand pump. You can find them at your local radio shack. If you're familiar with building a custom robot, desoldering a two pin connector is really easy:)


Yep, I've done lots of soldering and de soldering. I have a nice Hakko De-soldering gun that I love and works like a dream.

I do plan to desolder that bottom mounted power plug and add a pig tail wire and Molex connector to one of my new V4 boards that will be replacing the 3 exesting V3 boards mounted in my B9. I'll need to bring power in from the side because it's in a very tight area as seen in post #9 above. If you look close at the V3 board in that pic I've already desoldered that power plug and added the pig tail & connector because of space limits (well you cant really see it because of that big heat sink is in the way).

I just mentioned adding a side mounted power plug because skater_j10 mentioned replacing the programmer pins with an extra 3.3V and Gnd breakouts there if "us" guys need it. Just thought I'd through out that idea to see if it was feasible or too late in the design game. ;)


I must say, this is a very nicely done board!:)

DJ, thank you for starting this new venture full time when you really didn't have to back a couple years ago. Also, thank you for taking the time to create this V4 for us! I believe in your product and I believe in you to be very successful. Let me rephrase... I believe you will be even more successful in the year to come.
