Basic ESC and arduino - ESC in reverse

Blue Robotics Products Speed Controllers (ESCs)
1

I just bought a T100 thruster with the basic ESC. The sample arduino code shows the range as 1100 to 1900. However, how do I put the thruster into reverse?

 

thx

1100 is full reverse, 1500 is stopped, 1900 is full forward. Look at the technical write-ups for the ESC, they are on the product page.

The write up I saw just said the range was 1100-1900 regardless of reverse or not. Can you please post a link to the one that is more explicit as I can’t find it.

thx.

Go to the ESC product page and look down at the specs. It spells it out quite clearly.

Sorry for that mess!

 

Just go to the store and look at the specs for the ESC.

ooohhhhhhh thanks! I’m new to this and thinking of μs as a value to output from my arduino did not register in my tiny brain :slight_smile:
