Please read the warning before applying power to a bltouch or a servo.

The RAMPS 1.6 is the second RAMPS iteration released by BIQU/BIGTREETECH. It replaces the original green power connector with a pair of screw terminals, adds a larger heatsink over the MOSFETS, and has a larger bed MOSFET. It maintains the surface-mounted fuses and flush MOSFETS of the RAMPS 1.5.

Also, the positions of the D1 and D2 diodes have been swapped from the positions in RAMPS 1.4, the D1 diode is now the diode closest to fuse F2. The same is true for RAMPS 1.5, also manufactured by BIQU/BIGTREETECH.

Warning

Some third party versions of this board have a design flaw. The 5v line from J5 through to the 5v pin in the servo plugs are shorted to GND. Connecting the jumper J5 will connect VCC directly to GND and destroy the voltage regulator on the mega2560 board.

One brand of board that is known to have this issue is labeled "ZYLtech Texas USA" "RAMPS 1.6"

This is the logo from this board.

The issue was investigated and found to be a design flaw in the PCB, where by the J5 5v pin is connected to the GND plane.
