Palawan Rx Board changes
ECO1: Swap D11U pins
The diode D11U footprint and schematic pins are swapped. Correct this.
ECO2: Send USB pullups to VPP
The USB pullups on USBDN_RST and USBDP_LED are going to VUSB. They should instead go to VPP, otherwise USB will fail to function.
ECO3: Populate R15U with 1.5k, 10%
Enable low-speed USB operation by populating R15U with a 1.5k, 1% resistor.
ECO4: Make debug pins oval
The debug pins on the side should be made oval, for easier soldering
ECO5: Add GND, VPP debug pins
To make life easier, add pins for probing GND and VPP.
