Introducing the credit card sized Cardputer!!

In this video, I demo the ESP32-S3 Cardputer from M5Stack which is a hackable little keyboard device with Wifi, Bluetooth, Speaker, Microphone and more.

This is an interesting niche device for hobbyists who are interested in picking up a more complete development platform to tinker with.

Looks like this is back in stock you can find it called the M5Stack Cardputer. Unrelated but If you like small self-contained and cheap electronics like this, you may like my video on building one of the same microcontrollers which powers this into a Super Nintendo controller to store and play games. I've linked it in the bottom left of this video if you want to check it out!

Some people use Lego bricks to build support structures for hobby electronics projects. Which is probably the reason for the Lego connector on this.

This is exactly what people in the 70's thought technology would be in the 2000

Bout to become a cyberpunk net runner with that

"I'm not sure who this is for"

Doom players:🔥 😎 🔥

I was really impressed that they managed to pack so much in such a tiny package, but then i remembered i have a smartphone which has way more in a similar size

[GlorifiedGremlin]

This is for me, 20 years ago, when I was 8 years old and dreaming about a product like this

Now let's do an computer sized credit card

This thing has more oomph than the combined power of both the 386, 486, and Pentium 1 I had back in the '90s, which cost me thousands of dollars. The progression of technology is amazing...

I just ordered one. I’m building an rtu controller that can dehumidify for a restaurant/ballroom that has 6 Lennox rtu’s and they want almost two grand a piece for new control boards so I’m doing it for less than fifty bucks in parts and a little programming. This will help address the i2c sensors I’m installing in the ducts and ceiling. I’m also connecting them to the fire alarm so if there’s a fire it’ll close the economizers and tell the exhaust fan vfd’s to go to high speed while shutting off the rtu’s. It’ll be easier with all of the addressing the same for each unit so I can just copy the code and don’t need to change sensor addressing.

It can run a small motor with more complex functions like a time switch or temp switch. Rpm sensor or either patterns or an uneven time delay. In other words, it can run the fans, lights, and co2 or 02 sensors in you’re grow room and you can make adjustments on the panel. Plug it into a usb drive and it can run them all with with the right programming, You’re welcome. It can also run a mean model train set..

[Jambandit]

I know exactly what this is for. College level lego projects. Like the automated lego bridge building machine that lays a bridge, crosses it, and picks it back up. This is just the brain for those projects.

[SAMarcus]

This looks like an upgraded device for Lego controllers. The Lego MindStorm kits had simple controllers but this looks like Arduino taken to the next level.

[hansdampf]

I need this. I don’t know what for but I need it

[JetJockey]

I have a similar one of these, but it is just a big touchscreen called the M5 Stack Core2. It is an absolute beast of a prototyping machine. I have built more than 15 projects that I have since abandoned with it

[PrinceWesterburg]

Anyone who was into microcomputers 40 years ago will be as blown away by this as I am. Its just crazy whats around now and how fast, cheap and easy development is now

[nameless]

Someone will pair this with a Raspberry Pi and post a YouTube video on how to fly to Mars using the two and some bubblegum.

[humanplantman]

the lego mounting on the back is such a fine touch. It would make the hardware a little more fun to tool around with. Just like legos. Legos are fun.

[bleeb]

I use one of these with a USB to serial adapter as a network architect. It’s always in my pocket in case I need to access a switch or router in an emergency fashion, and don’t have my laptop and accessories. It’s saved my bacon more than once.

It's an ESP32, so you're not necessarily starting from scratch. There's a healthy community for ESP32 software even if that software might require some adaptation to match this exact device.
