[Physical object verified] Lichuang EDA Graffiti Version Universal Remote Control V2.0

Overview

Re-edit V2.0 version

Smaller and more compact, the chip capacitors have been replaced by plug-in capacitors, so you can just lie down:) The functions are just as easy to use!

Originally this thing should be smaller :)

How can I describe this project? . .

It’s so weird that even I don’t dare to put the LOGO on it! ! !

The graffiti version of the universal remote control has 7 infrared transmitting tubes and super energy. Even I am afraid of it when it is launched~

No matter how you look at it, it doesn’t look like a serious remote control~

Thinking about it again, maybe it should be made into a round set-top box shape and hung somewhere T_T...

I want to change my project, so I asked Tuya. For a module that has been finalized, you need to buy a new module to upgrade the firmware. You need to buy a new module to change the product type. Yes, you need to buy a new module no matter what you change.

Forget it, this time the outstanding award will be reserved for the majority of Lichuang EDA enthusiasts, cry to death! ! !

PS: Because I need a 470UF capacitor, I designed this package that can be both patched and plugged in. Don’t be surprised. . .

Updated on December 2, the project has been completed, the air conditioner can be controlled remotely (the wind direction cannot be adjusted, bad review!), and the Xiaomi TV can be controlled remotely:)

The infrared transmitting tube is not forced to tilt, and the receiving end can basically receive it. The launch range is still very good!

Let’s talk about the shortcomings: Occasionally, network lag occurs. I press the mobile phone console several times, but the TV does not move for several seconds, and then responds violently several times. If I increase the volume, I will be confused. This should be the same as The graffiti module still has something to do with it.

Attached is a demonstration video for reference only:)
