Konoha
About the Konoha PCB
Konoha is an open source PCB design by aisuneko, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 80 × 80 mm, with 97 components from 31 distinct parts.
Other key parts include the CH634X, HD3SS3220IRNHR, TPD4E02B04DQA, WS3202E61-6/TR and CH213K. By type, the board carries 39 capacitors, 26 ICs, 22 resistors, 6 connectors, 2 diodes and 1 crystal.
From the project
4-port USB3.0 pure Type-C Hub powered by CH634X
4-port pure Type-C USB3.0 hub, based on WCH CH634X.
We have: - All 4 ports in Type-C - max. approx. USB3.2Gen1 transfer rate (~500MB/s); compatible with USB2.0 - Dedicated charging port - Adequate ESD protection - A symmetrical look - One-sided components for ease of assembly
Name is inspired by Akisato Konoha from 16-bit Sensation.
Aside from my original idea of forcefully converting the three USB-A downstream ports provided by the CH634X to Type-C, it is largely based on CH634X's reference design with modifications.
