Good build quality.
The jumper for enabling onboard 5V generation is nice.
Leds on the inputs are very useful for debugging.
Can't see the reason for pull-up resistors on the inputs(see other thoughts). For security reasons I would put pullDOWN resistors, if any.
Plastic parts of the screw terminals are somewhat loose on my board (I bought only one), but that does not caused any problem.
Got the same problem with supplies over 20V as FakeName describes
The 5V_EN jumper connects the 5V generated from the motor supply (VMS). If you let it open you must provide 5V to the board, either from the screw terminal or from the pin.
CSA and CSB jumpers are for current sensing: the current on the motors pass through then.
UR1 to UR4 are for setting pull-up resistors on the inputs. Can't see why.
IN1,IN2 controls motor A.
IN3,IN4 controls motor B.
