Palawan DVT represents a complete redesign. The main MCU has changed, and we now use a SoM for the radio.
Palawan Rx ECOs
- ECO1: The LED footprint and schematic symbol have mismatched leads, and should be flipped around.
- ECO2: RFM69HW DIO0 is connected to a pin that cannot generate an interrupt. Move DIO0 to PTA10.
- ECO3: There is a ground (and power) plane directly under the RFM69HW. This should be pulled back.
- ECO4: The LP3982 footprint has no "Pin 1" marker. Add a Pin 1 marker.
- ECO5: The KL02 footprint has a non-obvious "Pin 1" marker. Make it clearer.
- ECO6: The board is four layers. This is unnecessary. Make the board two layers.
- ECO7: The "Pair" button is not connected to a pin that can do ADC or IRQ. Move "Pair" to PTB7.
- ECO8: The LED is not hooked up to a pin that can do PWM. Move LED to PTA12.
- ECO9: It is unclear whether code is running on Tx or Rx. Change R101 from 22k to 2.2k.
- ECO10: The ESD diode's footprint and schematic symbol have swapped leads. Swap the pin number mapping.
Palawan Tx ECOs
- ECO1: There is a stray via on the board. Run DRC prior to exporting to gerbers to repour copper.
- ECO2: RFM69HW DIO0 is connected to a pin that cannot generate an interrupt. Move DIO0 to PTA10.
- ECO3: The KL02 footprint has a non-obvious "Pin 1" marker. Make it clearer.
- ECO4: All diodes have their schematic/pcb footprint pins swapped. Fix this.
- ECO5: Through-holes are not .1" spacing. See if it isn't possible to fix this.
Pins:
PAIR - IRQ, ADC (PTB7 is the only match) LED - High-current, PWM (PTA12 is the only match) DIO0 - IRQ (PTA10 is closest)
