Leds using a old servo board question

[Nikaem]

I have used the servo boards a lot it works fine but I add a resistor to each LED the rx olnly puts out 6vdc so there is a simple chart for the value of each LED
Color resistor value Voltage Drop (V)
Red 200ohm 2
Green 195 ohm 2.1
Blue 120 ohm 3.6
White 120 ohm 3.6
Yellow 195 ohm 2.1
Orange 190 ohm 2.2
Amber 195 ohm 2.1
Infrared 215 ohm 1.7
Other 200ohm 2
I got this info from
https://www.allaboutcircuits.com/too...or-calculator/
also I have saved myself a bunch of time by using single pass rc switch

you do not need the board unless you are using it as a switch. you can run direct to the battery port on the rx . I only use the 200 ohm resistors for everything some difference in light output but it is minimal hope this helps
