Buck Converter #22

Open najdanovicivan opened 7 months ago

I have AUX Climate which originally uses BroadLink WT1HB12 module.

AC provides only 12V to the module not 5V which is to much voltage for the LDO

The orignial module has 5 PINS

TX RX EN - Enable pin for step down converter GND VDD - 12V when EN is HIGH

Can we make updated version of the dongle which will have option to use step down based on something MP2307 or MP2315 for smaller footprint instead of LDO ?

Hello everyone 👋🏻 I'm back with an update...

I had the same problem that my Aux to USB had 16V, so I designed such an adapter - Buck Converter. And everything works great! 🔥🔥🔥

What do we need:

Below are some photos of what it looks like, let me know if you are interested in the files so that you can order such tiles?

@dudanov What do you think about this additional adapter? Maybe it's worth adding this to your documentation?
