Confused as to which voltage device I need to purchase to programme the ArduPilotIntend to run the ArduPilot from my brushless ESC which has a 5v BEC supply. Had thought I need to buy a 5v FTDI board but links on Sparkfun direct you to the 3.3v version.
You need to be a member of diydrones to add comments!
They also have the 5V version but that won't work. You can get a USB cable from the DIYstore that has the FTDI chip built in so you can use it to power the board at 5V and transfer serial info to the TX/RX pins at 3.3v level. http://store.diydrones.com/ProductDetails.asp?ProductCode=TTL%2D232...
