Unique features on the new NanoboyS3 board 1. A digital switch is added to turn off the battery level test circuit after the test is done. It will reduce deep sleep current significantly. 2. With a Low Pass Filter, the battery charge status LED does not flicker when a battery is not connected.
3. Long Reset Press
(LRP)
to enter bootloader mode, it's
simple and easy, press the reset button until a red LED
is lit 4. With an ON/OFF power switch, the battery does not need to be unplugged. At the end of day, you can just turn off this switch and do not need to unplug the JST battery connector and the USB cable. The power LED will still be on as long as the USB cable is plugged in, but it will only draw a very insignificant amount of current from the USB hub. No current will be flown out from the battery.
5.
Able to play the flappy bird game and other simple video games.
