When charging, the chip is hot.Can be normal use.9.2v,Chip heating is caused by low voltage? Battery selection, 25C / 20c / 30C / 35C?What are the requirements for battery selection?

It seems like I'm going to buy a second-hand DNA40 with big screen.

Dna200's screen is damaged, and in China can not buy, only to find the 14pin interface. Is there any way to solve it?DNA40's screen can be common?

Thanks Mad Scientist, I will try to re weld all the connecting lines.

Thanks UKDTweak and Mad Scientist, I don't have a clear description of my question. Even if I do not use USB charging function(external charger), all of the connecting line is necessary?

Thank you very much.

I want to use two 18650 batteries instead of battery in vtbox200. Space(72*35*22mm) should be able to lay down 18650?2 battery box. 1.Can I just connect the output line to the dna200 chip and USB only for updating the firmware? 2.Annex can be used for all 18650 * 2 ? 3.I have to do is to update the discharge curve, choose 2-cell?

After two days I will receive the vtbox200, I will be here to do a comparison.

Sorry for the wrong place.

I am a Chinese, English is not good, I hope to express clearly. Must pay attention to the default USB connection virtual machine, Prevents usb disconnection when the firmware updates.

My computer is also Mac, you can use the virtual machine. But to pay attention to setting the default link USB virtual machine.

Dna200 chip, the fuse is burning, can I fix it myself.I judge the box is for this reason to stop working.

I found a new yihi SX Mini ml class? chip 350jv2. in response to dna200.
