DRV8313 driver system board

 
Overview
The DRV8313 minimum system board
uses a two-layer board design, with JLCPCB providing free prototyping (thank you JLCPCB!).

It features three input pins and three output pins, with pads near the output pins to support direct wiring for non-2.54mm interface motors.
The three input EN pins are combined into one and enabled using a jumper cap on the board.
The sleep and reset pins are also provided, each manually enabled using a jumper cap. The sleep pin is internally pulled down by default; theoretically, leaving this pin floating will put the chip into a low-power sleep mode (unverified). The reset pin is also internally pulled down by default; its description states that a low level disables the output and initializes the internal logic (unverified).

All surface-mount resistors and capacitors are packaged in 0805 for easy soldering.
The FAULT pin outputs a low level when the chip is
under overcurrent protection, short circuit protection, undervoltage lockout, and overtemperature protection (not used). An LED is connected in the circuit to indicate a fault when this pin outputs a low level (except for reverse connection, which will burn out the chip). Future plans include adding overtemperature protection, reverse connection protection, and a switch. The board is relatively simple; please be gentle with your criticism. I am open to friendly suggestions and opinions.
