I tried with Arduino using loops and max7219 plus RTC lib …kept loosing time and it comes with cr3032 which is wrong and should be lih3032 rechargeable I tried an 18650 until I found out it charges to 4.35 😂😆
8;40 it started flashing when power output was 4.59 volts,its telling you voltage too low
I love pro micros and pro mini's. So damn useful.
nice you could also put a switch on the sorder bridge if you want to be able to switch more easily
can it check voltage drop on a cable? I ordered one that looks just like it that claims it can show the voltage drop on a cable when plugged into the USB mini.
I guess it's the "4884 Joystick Shield" you'r using in your Arduino Clock – would you recommend it? Nice menu and love this way to set the seconds, really cool idea!
nice gadget. I wish the Chinese would include instructions. did you ever find a manual for it?
USB LCD Doctor, double click LCD will flash, while LCD flashing click once to go to the next number, double click again lock to the select number….to reset the number click 5 sec will reset the next number to zero.
Id like to buy one of these usb testers to check a few cables and charges i have.
For a complete layman how would i test which chargers and cables are the best for fastest charge.
hi Julian, i'm little bit curious about voltage usb meter, since you have so many type of usb meter, if you don't mind… can you plug all the meter on series and we'll see about the accuracy, and show it to us?
The Micro-USB port on the charger tester is for power supplies with a permanent USB lead
