Prototype Shield equivalents?

Would you like to see more information or a tutorial about how to do something with LattePanda? Post requests here!

When I get everything ready for my robot, seems I will need to hard wire my connections. From what I've seen, most Arduinos use a prototype shield like this: https://www.dfrobot.com/product-55.html

The LP isn't pin compatible with shields. I've read up enough to know that part. My question is, what is the equivalent to a prototype sheild for the LattePanda, or can we have documentation on how to connect the LP to a shield?

Dear QuiGonJ,

Great to know that you're using LattePanda to build you robot. The photo attached is a project that we're working with DFRobot to provide a Arduino stackable shield for LattePanda.

It will be available in the recent two months as I know. It comes with the onboard power management to handle the 7-23volt input, which is necessary for the complex embedded application like robot, which commonly use 12v/24v power battery. And it's compatible with modular sensor from DFRobot store.

Otherwise, here's also a open source LattePanda Arduino shield design shared by a user.
Check out this link: https://github.com/meerstern/Lattepanda2Arduino
You can make your own also.

And except the shield conversion, you may consider to purchase DFRobot gravity sensors or grove sensors from Seeed. All these modular sensors can be connected to the 6x 3 pin sensor port designed on LattePanda. :)
Enjoy Tinkering with LattePanda ! :lol:

Excellent! Thanks for the reply. I am not in a rush to finish the project, so I will wait the two months for this product. The power supply I am looking at is a 12V 20aH SLA battery, and I am using a fusebox as well to protect the electronics. The robot will have two drive motors and a car antenna accessory that goes up and down for a "probe". They will be controlled by the Sabertooth 2x25 and a Syren 10. Dimension Engineering already provides Arduino code for those, I'm happy to say.

Something else has come up though. I did download the Visual Studio, and was going to download the Lattepanda Firmata for it. But going to GitHub, it says click on Download zip, but I do not see a download zip file to click on. Am I missing something?

Wow. You know Sabertooth drivers are definitely best robotics motor driver in my opinion!!! I love that! The response is quick and the emergency stop effect is just perfect. And we will update the product status here if it's available from the market to notify you. ;)

Considering that you're using Sabertooth, I assume that you're building a mobile robot, right?

For the software downloading problem, please check the screenshot here.

Thanks for the instructions!

Yup, He's mobile. He's a full-size replica of K9 from Doctor Who, to be specific. I have a skins kit, the frame, scooter motors for propulsion, his ears, his collar made from a Scottish tartan that a cosplay friend made for me, the ducting needed for his neck, the Syren for his probe and the Sabertooth 2x25 for his front drive wheels. In terms of a content request, I am not entirely sure how to connect the LP to the motor controllers. Any pointers on where I can learn how?

Here's the basics of his wiring diagram, so no, I am not asking people to make this for me =)

Since it has been nearly two months, just checking in ... any word on this?

Not to be a noodge (he noodged), but you said three months ago it would be ready by now. Any news?

Hi, happy to know you still have interest in this Expansion Shield even we are slow and inefficient :oops:
In this three month, we finished a little update on the stability of high current and some bug-fix. I think it is better now to play a role as the voltage regulator to drive the LattePanda with the “12V 20aH SLA battery” you said before.
But we just had a long vacation of the National day in China, it has a delay in production. So I believed the shield will retail at the end of Oct. :lol:

May I ask how many shields you will order?
Because we notice that you have a project need to do, Can you share us more detail about it ? It's a good opportunity to get a prototype now if you would like to review this product. ;)
Enjoy Tinkering with LattePanda ! :lol:

Just one at the moment. Are you familiar with Doctor Who? It's to make a K9 replica. It's a tin dog.

https://en.wikipedia.org/wiki/K9_(Doctor_Who)

My older build diary: https://www.flickr.com/photos/rick_r/al ... 3968412954

Once we figure out the circuitry, then the board would let me create actual circuits instead of just breadboarding something.

[edited to add: The idea is that when I am done, I can make basically a recipe for others to make K9. I would include all 3D printing files, programming, wiring diagrams, etc. so that others can just make their own. It's like how making Artoo-Detoo units has become a hobby for many people. Working on K9, everyone seems to do their own thing from scratch. If I said, let's do this, this and this, and then use a LattePanda, so much the better.]
