Update, as well known, I brought this OIC module, Mini USB Arduino Nano V3.0 ATMEGA328P Module.
This module has about 10 output, some especially for LED flashing. But max Iload are about 50mA, norm. 5V, and need a sample for using MOSFET gain out stage. Spec. Ucc main power 15.2 V DC, (delivery 4480mAh from 3S li-Po battery). LED 3W, main work voltage RED: Forward voltage supply: 2-2,5V, 700mA forward current. GREEN: Forward voltage supply: 3,2-3,6V, 650mA forward. Think I use 2 green LED, and 2 RED led. Pattern: 3 flash green per sec, RED 2 flash each 2.5 sec. The mention to use high power led are to visually better see position at drone, during FPV operation. I think the question are to conver 15,2 main supplies to eg. 5V, but this IC regulator shood match 1,4A when 2 red flash. Thin I have to make pattern when red light, the green are off, else I need regulator handling 1,4A+1,3A (=2.7A IC regulator=3A) when red are lighting at same time as GREEN lighting. To reserve power to UVA-drone, think this pattern at flashing need to occur each 45 sec.
Some one with type MOSFET (N-type), measured resistor value simple diagram? Thinking, using IC regulator, from 15,2 to 5V does not mention to left more power likely to the UVA, because main current ned to flow throughout this IC-regulator, correct?
