Overview
MicroZed IntanInterface-2Layer is an open-source printed circuit board by kemerelab, from the kemerelab/MicroZedIntanInterface repository on GitHub, published under the MIT licence. It is a 4-layer board of 100.3 × 101.6 mm with 114 parts on 193 nets, routed with 1,070 tracks and 245 vias.
It is built around the FT230XS-R, AP331AWG and BSS138, with the BAT54C among its other parts. Its parts include 30 resistors, 25 capacitors, 10 diodes, 9 ICs and 6 switches.

README
pcb/KiCad-Project/README.mdKiCad design files and production files
The PCB design was dervied from work by Viktor Nokolov licensed under the Creative Commons Zero license. His original project can be found here https://github.com/viktor-nikolov/MicroZed-carrier-board.
Revision 1.0 Notes
Board revision 1.0 fixes the bug in 0.11, and transitions from 2 layer to 4 layer fabrication. This allows for a smaller and slightly more case-friendly layout (digital IO on the same side of the PCB as Intan/Omnetics connectors, and USB-C power moved to the same side as the ethernet connector).
Revision 0.11 Notes
Board revision 0.11 was used for initial testing. There was an error in the connectivity for the USB-UART bridge. We fixed this with a bodge that is circled in the image below.
