    Hi,
    I bought it recently, and noticed that the on-board regulator is getting pretty hot even at 6V input. I searched for the data sheet of the regulator and I was surprised to see that the regulator is 150mA, but the LCD on max brightness uses more than 200mA. I haven’t measured the exact temperature, but I can’t hold my finger when its hot, so I guess its not very healthy for the regulator. At 50% brightness, the current is exactly 150 mA and the regulator is only warm, so I guess that would be the max brightness I am gonna use.
    I also want to ask is it possible to program the on board atmega 168 without removing the chip? If yes, then what kind of connection, programmer etc to use?
    Thanks in advance
