Hi there!

It sounds like you’re working on converting your InMoov head from MRL to an EZ-B/IoTiny setup. I’d be happy to help clarify the process and point you toward the resources you need.

Below are some details and suggestions:

1. The Role of the IO Tiny and Switch
   In the EZ-InMoov head design, the IO Tiny is used as the interface between the head’s servos/sensors and the EZ-B controller.
   The switch you’re referring to (located at the back of the head) is part of the design that lets you change power/control modes or signal a certain state. In the EZ-InMoov hardware, this switch is integrated into the mounting bracket/connector that holds the IO Tiny in place.

2. Where to Find the Parts & STL Files
   The EZ-InMoov Robot Head product page on Synthiam’s website provides detailed assembly instructions, parts lists, and STL files for 3D printing the necessary components.

   • Visit: EZ-InMoov Robot Head Support
     In that support resource, you’ll find the assembly PDF and links for the 3D print files for all custom parts (including the bracket for the IO Tiny and the switch assembly).

3. Adapting Your Current Head
   If you’re rebuilding your head, compare your current setup to the EZ-InMoov head documentation. The provided mounting hardware and wiring harness are designed for the IO Tiny and EZ-B integration.
   If you’re missing a particular bracket or switch piece, the STL files and parts list on the support page will show exactly what you need to print or order.

4. Wiring & Integration Tips
   The IO Tiny is wired to handle the servos (for jaw, eyes, head pan/tilt) and any sensor inputs. The documentation explains how the IO Tiny mounts into the head assembly and connects with the existing wiring harness.
   Double-check your wiring against the illustrated diagrams in the assembly instructions (often included as step-by-step guides) to ensure that the switch and IO Tiny connections are correct.

5. Next Steps & Additional Guidance
   Review both the hardware page and the assembly instructions to see how the IO Tiny is integrated and how the switch is mounted.
   If you need more specific help (for example, wiring clarifications or additional pictures of the switch integration), let me know what details are most unclear, and I can guide you further.

I hope this gives you a better idea of how to proceed with your modification! Do you have any questions about a specific part of the integration or the wiring diagram? Let’s work together to get your EZ-B powered InMoov head up and running.

Don't know if this is what you are looking for or not?

Good Luck

@bhouston that is for the head itself. I'm not looking for that I'm just looking for the part that has the mini deans and power switch on it. I don't see it in the STL files. I have most all the other parts as I have a ez-robot developer kit plus extras. I'm sure that part was a 3d printed part at some point.

Here is what it looks like again:

You can see the switch, a micro deans, deans, and a spot for a fuse.  It's the blue part I'm needing.

@Nomad-6R That's it. Thanks everyone for the help. Much appreciated

The great news is I have the part number now and its really cheap.  The bad news is that since US is NOT so happy with Canada just to ship it literally across the border into Montana is $40.  ..  I wonder if there is anywhere here that I can get it?

I saw a post a while ago that said ezrobot has a warehouse in the USA. You can reach out to ezrobot and ask about their warehouse.

hi dj

the page on ez robot for finding a retailer is gone .

mwannabe

can you solder ? i have the board , switsh , and cable . i can send it to you .

@DJ-Sures there used to be a page, but its only a 404 error now which is unfortunate.

@Nomad_6R Soldering no problem. Surface mount no problem. I will take you up on the offer. I'll DM you with the details and hopefully can get this. That would be awesome and I do appreciate it.  As such, I just reached out to you from a cluemail.com email address.

Thank again

I think the post @DJ mentioned about the US warehouse was mine. I called EZ-Robot over a month ago in early February and asked about a bottom board for a EZB. They told me they had on in stock in their US warehouse (can't remember the state). I order it through their online store on their website. Shipping to Florida USA from that USA warehouse in early Feb for that $50 board was $30. A total of $80. That was before all the Tarif stuff. Now Fast forward to now after the Tarifs started. I reordered the exact board a couple days ago. Costs were the same. $50 for the board and $30 for shipping. No change due to tarifs. I've been buying from EZ Robot for over a decade and they have always had high shipping costs.

I've been buying my EZ Robot stuff from the RobotShop. They have a good selection (when in stock) and ship quickly and for much less money. Sadly I checked and they don't have the part you are looking for. Here is their web address link: https://www.robotshop.com/

@Nomad has an excellent solution. Make your own when ever possible. LOL!

hi dave

i also by my stuf on robotshop . indeed mutch cheaper and fast shipping .

i just asked them for micro HDD servo's from ez robot and they gonna take them in stock .

@Nomad, ya, they seem to have been out of stock of a lot of EZ Robot parts lately.

did you recieve the connector ?

@Nomad-6R.

Check your email.  I owe you

@Nomad-6R I did receive it.  Thank you very very much.   I also emailed you back.
