YATA
About the YATA PCB
YATA is an open source PCB design by virtualsecureplatform, published on GitHub under the AGPL-3.0 license. It is a 4-layer board measuring 100 × 100 mm, with 69 components from 25 distinct parts.
Other key parts include the SN74AXC4T774QPWRQ1. By type, the board carries 51 capacitors, 14 connectors, 3 ICs and 1 resistor.
From the project
RTL of YATA without NDA related things
This PCB is designed using KiCAD 9. For assembly, most of the parts can be purchased from DigiKey or Mouser, but SMA connectors and probe sockets are purchased from a local Japanese store.

I recommend replacing them with your favorite ones if you plan to reuse this PCB design. There is a sense register for measuring current, but we did not use it because the noise seems too high.
