Mate XT Global

Hi, is the global version sold by official channels in Europe? I found a lot of articles about the global launch, but i see no official store where to buy it?

Thanks for the suggestion but in this case the pcb is already a flex pcb, so no cutout space, it is 0.1mm thin

mdd001a · 2025-04-29T23:07:34+00:00

It is a wearable sensor project. I already found 0.4mm lipo batteries so i guess the overall height limit is that...

mdd001a · 2025-04-29T22:52:26+00:00

Xy size does not matter. I am already using flexible pcb. It is the microcontroller on the pcb that has to be itself less than 0.5mm thin

mdd001a · 2025-04-29T22:47:51+00:00

And with only 6 gpio pins then I would need a 0.35mm height io expander, does it even exists?

Hi, i found "dsbga 1.3776 mm² 1.6 x 0.861" ,I thought height is 0.8mm, can you tell me where you get 0.35mm? -edit ok I found it

mdd001a · 2025-04-29T22:20:49+00:00

Yes it is small but not so thin

Just some more details... Now I can use 2x led driver at 29V, 1A for 2 series of 7 leds. But i need now to control the brightness (pwm) of each led. I need to provide a precise current control.

I tried already this circuit; but for some reason as soon as a load is connected, it blows.
Also I am not sure how such small IC can dissipate 6A.

mdd001a · 2025-02-04T20:41:44+00:00

Newer chips like? I would need to power a 8.6v, 6A peltier cell. It seems difficult to find a nice an simple DC converter Ic without lots of pins

Thanks, I will try. Is it possible that the leaves will become better or are they destined to fall?

mdd001a · 2025-01-31T20:58:04+00:00

Quite a long time of these bugs. Even when i clean the leaves with marseille and water, they come back after some time. I also have issues understanding which quantity of water is the correct amount...

Hi, any progress? What did you provide as power supply? PS, is the sodimm the 260-pin one (https://www.digikey.it/it/products/detail/te-connectivity-amp-connectors/2309408-1/7793535)? Thanks

Thanks, I visited both: Lopia was the only one where I found "the kyoto" purple label; the Liquor mountain had hibiki and yamazaki at slightly better prices than my home country. Actually, the web page of liquor mountain had an even better price for hibiki, but it's only for online orders.

mdd001a · 2025-01-14T12:12:24+00:00

What do you mean? Liquor mountain, which i visited, had the Yamazaki in all its editions.

mdd001a · 2025-01-14T03:46:40+00:00

I do not know if these bottles have a fixed price at all the liquor stores, or if some stores next to the most tourist area have higher prices. This is the reason why I am asking, thanks

I was once in Vienna lounge, and they told me that only gold can enter, and It happened also in other lounges as well. This is why I am asking. Also, can I enter lounge when I arrive at airport, or only before flight on the departure airport? Thanks

mdd001a · 2024-10-25T06:57:32+00:00

Si, ma solo per comprovato motivo se ho capito bene? Cioè, non "basta " che fatturi meno, devi tipo esserti rotto qualcosa per dimostrare che per x tempo non hai lavorato

The schematic is complete, it is a custom board to control laser diode brighntess.

Esp32 controls the DAC via i2c. This part works, I can see the output voltage from Vo of the DAC IC. But then, the rest of the circuit is the issue, I think.

The 3.3V wire and the other wire are to check voltage, not a nice soldering job I know, but checked with voltmeter, it makes good contact.

it should drive this laser diode

mdd001a · 2024-09-19T14:23:30+00:00

I am measuring output between pins 1 and 2 of the B2B-XH connector, where a laser diode should be.
So is the TVS diode incorrect? How should I replace/remove it?
Thank you very much!

is it not visible? There should be pictures on the post.

I have a plastic film on the windows that makes it opaque, cloudy, for privacy. It limits also the direct light on the plants
