While messing around with the Hipstreet tablet I dropped it and cracked the screen. I bought a Unbranded (that is the brand name) 10″ tablet. It had the same Intel Z3537F quad core processor and 2GB main memory. It was also a 32GB storage. It also was upgraded to Win10. I then tried the OTG cable with the power injector. A no go. One end worked for Data, the other for power. It would not work as data and power no matter what I tried.
Next I tried to get a data connection through the keyboard connector. No luck there. It needs a pull down to activate the data port. No firm information on the resistance value. It could be 10K or 100K ohm. After checking the keyboard connector I could no longer charge the Tablet. If it wasn’t for bad luck I would have no luck at all.
So I opened the tablet up. I cut the battery leads. I soldered a small Molex connector into the board. I reduced the LM2596 to 4.1V. Now the tablet is directly powered. Now I had power and Data both. The power system is not optimal. I would like to have the battery in the system as a surge source. I have had some power crashes.
The Control Center works well, but it can take a while for the date and time to correct themselves. The 10″ screen is not as clear as the 8″ was. And the scaling is different. Overall I liked the Hipstreet 8″ tablet better. It was faster (better SSD I believe) and the single cable was a cleaner installation. Size wise the smaller tablet was better overall.
I found it is nice to use a Bluetooth keyboard in conjunction with the tablet. Makes it much easier to change print settings. I setup a public account within my local network. This allows me to send files from my other computers to be used on the tablet. The one problem is the inability to use a USB stick in the tablets for file transfers.
What to look for in a control center Tablet:
Separate power and USB ports. Much easier to setup to operate with the printer
2GB main memory. Allows you to open a web browser while operating the printer.
Decent quality screen.
An extra USB port.
Bluetooth keyboard or Keyboard connector.
I will get you some pictures later.
