A naked scheme, is this true? [Copy link]

 

 

I saw a new evaluation development board on the forum. It is simply a smart watch solution, and it uses Raspberry Pi! Add a battery, a heart rate sensor, and a case, and it becomes a watch.

Below is the hardware information. The market reference price of so much hardware is: 88.9￥ which is really cheap. It’s not a small amount of money just for a screen.

This board is interesting. Really good, it would be even better if it was made with esp32. WiFi, Bluetooth directly connect to mobile phone.

Isn't it fun to make a pocket watch? It's really cheap, it's worth buying without reviewing it.

Yes, this can be made into a stand-alone watch~

Yes, I think the normal price of this set is about 200.

It’s really great, but it’s not worth it if it can’t connect to a phone and is just a digital watch.

If it is true, will those watches that cost thousands of dollars have no market?

When I saw the watch development board, I was reminded of TI's eZ430-Chronos development board from years ago, which cost 400 yuan back then.

Except for the small flash capacity, everything else is good. It looks like it can be developed with C/adruino/micropython, and it would be even better if there is a suitable shell.

3D printing is OK for making a normal shell, but the effect of this kind of high-quality product is generally not very good.

This shell 3D printing is too ugly, it can be CNC,

It's a monochrome screen

3D is more convenient and saves money!

If it is replaced with a Bluetooth soc, plus local AI support for voice recognition, this is definitely a business watch.

Does the watch support voice recognition now?

wangerxian posted on 2022-10-18 11:34Do watches now support voice recognition?

There are some, and several domestic chip manufacturers are also making watch soc, tws headset soc, this kind of, generally support

Last year, Weiwei evaluated our chips and those of another friendly company for its watch/bracelet project. However, Weiwei later cancelled the project due to product planning issues. It was a pity that they had even made the PCB at that time and failed to complete it, otherwise they would have been a supplier of Weiwei.

They mainly use the local voice recognition function and recording function, etc., just to recognize some simple command words to start some functions. What they want is low power consumption and accuracy. The kind of thing like Xiao Ai must be connected to the Internet, and this kind of soc cannot be realized locally

Aren’t electronic watches in Huaqiangbei just over 200 yuan now? Although they are not very good, they have a wide range of products.
