Hey! The schematic seems to be a 1:1 copy of the tutorial from the journal. The readme has extra stuff, but the changes should be journaled! I can't see the reciever in the journal. Please check out https://blueprint.hackclub.com/about/submission-guidelines, and ping me if you have any questions in #blueprint-drafts! Remember, all changes should be in the journal :)

Thanks for listening to previous feedback! If you could just add your shipping option for your pcb in your cart screenshots that'd be great :D

Hi, this appears to be a pretty direct copy of the tutorial, please try to add one or two things (temperature sensor, to name only one example) to differentiate yourself. Additionally, please use Economic PCBA instead of Standard PCBA. Thanks.

Routed the PCB

Its the next day , I sat at around 7:30am started to route the pcb before going to college. I closely followed the tutorial and I tried my best to exactly replicated the routing like kai. I did face some issues like with the same track length for the D+ and D-, but then got it right. I just need to add some cool silkscreen to it.
