Im curious about 40X2, I will get it soon, surprised that 40X2 is different low volts, max 3.3 volts not 5 volts like for 08M, 18M, 20M, if do 5 volts cause will damage, 40X2 must max 3.3 volts is that correct? what kind value regulated 3.3volts? like 7805 for 08M etc. LED should less resistor about 180-390ohms (5-20mA) for low volt 40X2.
40X2 need use crystal 4Mhz as normally time? like pause 500 will almost correct 0.5sec by normally rest 4Mhz crystal?
