I've been working to recover from accidentally pulling my Arduino out of the female header pins. Since it reconnected when it landed and burned itself up...it also burned up a number of other components. I've replaced the motor drivers, the 5V regulator and the Arduino. Next I need to replace the microSD module which also burned out. Also, the serial portion of the SF30 was damaged, but the USB side still works. So I can either switch to the LidarLite 3 which has arrived now, or I can get a usb to serial module to put between the SF30 and the Arduino (I'll eventually do both so I can compare the two sensors). I'll probably work on the LidarLite portion while I wait for a USB module to come.

That being said...It took all of 2 seconds to accidentally yank that cable, but it will take 2 weeks to repair the damage. I had used headers to try to make it easier to switch parts and to prototype...but that seriously backfired here.
