LDO
@gohan
Hi, i added a WDT now into the MotionSensorSketch.
Well at least i guess i did. I just read about it , never used it before. Does the 1Mhz Optiboot boatloaders support this ?
Unfortunalty I didnt recieve my 3,3V boosters yet and i dont have LDO´s around.
Concerning the bootloaders. Do you have a suggestion which one to use ? As I read that sticking to 1Mhz is important when using only 2AA batteries because of instability when voltage goes belowe certian values.
Obviously i could use more batteries, but then i cant supply the nRF2401 from the board right ?
