Only a few minor comments to be fixed

• Can you run the ERC. This brings up errors about the unused pins on the main chip, it might be worth replacing the labels with unused pin crosses
• Are you able to put one of the LoRa pins on to the back copper to remove the serpentine, specifically the LoRa pin 15 GPIO 17
• The DRC also has a few errors, most are from the USB C connector that can be ignored but there is a minor complaint about clearance around VRG_AVDD
• There is a warning about the BME text not being flipped which might be worth fixing

Other comments:

• Why 4 layers, and any reason for 2 grounds?

Do you mind also putting the CUSF Logo onto the board and feel free to put your name in the silkscreen. The logo is in the drive (logo-black.svg)

Hi, thanks for the review! Will fix the ERC errors soon, I had originally left all the GPIO pins labelled incase we needed to add/remove anything to them. Fixed the serpentine trace as well.

USB-C errors can be ignored, the footprint is well within JLCPCB manufacturing limits. Will fix the text soon too and add the logos!

As for the 4 layers, it's needed for the 50ohm impedance matching required by the LoRa antenna input traces (although it is quite short). 4 layers is also not too much more expensive (maybe $5) and is nice to have.
