Hi,
I am new to netduino and MCUs and I just got a new NETDUINO PLUS 2.
Can I use all 14 digital I/O's as output , driving 14 LEDS ? That's about 14 * 20mA = 280 mA. I read from the spec that Idd for the microcontroller should just be about 93 mA at ambient temp. Is it possible to drive all 14 I/O's for running LED's without exceeding the Idd in spec sheet ?
I was thinking about instead of current sourcing, I will just apply 5V external power supply and just make the 14 I/O pins sink or ground the LEDs.Will that make any difference ?
If not, what is the best solution to drive all 14 LEDs simultaneously using the NDP2 ?
Please help.
Thanks.
