PCB Rev. 3
This is the third revision of the noisemeter (now tRacket) PCB. The design is more or less finalized at this point, and has been prepared for larger production and meeting safety and regulation requirements.
- Board dimensions were reduced to a rectangular form factor
- Replaced "Noisemeter" silkscreen with "tRacket" logo and URL
- Optimized BOM to reduce total component count
- Added electrostatic discharge (ESD) protection to the USB port and button
- Verified BOM to be RoHS complaint
- Cleaned up signal and power trace routing
- Boards are to be ordered with ENIG surface finishing
The PCB is simply programmed through its Micro-USB port; follow the repo's programming instructions.
The board's UUID will need to be uploaded to tRacket's server for device registration to work.
