Overview
Rioctrl quadenc4 is an open-source printed circuit board by festlv, from the festlv/rioctrl-hw repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 2-layer board of 100 × 100 mm with 121 parts on 109 nets, routed with 930 tracks and 230 vias.
It is built around the CS48505S, USBLC6-4SC6 and BSD5C031V, with the UPZ1608E101-3R0TF, PESD5V0S1BBN and R-RJ45R08P-C000 among its other parts. Its parts include 64 resistors, 20 ICs, 16 capacitors, 8 diodes and 5 connectors.

README
rioctrl-stepdir4/README.mdrioctrl-stepdir4
This module provides 4 axis of step/dir/enable signals.
- Step/dir signals are differential 5V.
- Enable signal is at the same voltage as controller's DC input.
The connectors are RJ45 (intended use is either with motor-drive specific breakout board or a generic screw-terminal type breakout board).
RJ45 green LED is wired to enable signal.
Pinout (when using breakouts/rioctrl-rj45-breakout):
| Pin | Signal |
|---|---|
| 1 | Step + |
| 2 | Step - |
| 3 | Dir - |
| 4 | Enable |
| 5 | GND |
| 6 | Dir - |
| 7 | GND |
| 8 | GND |
Changelog
v1.1
- Fixed slot's pin-header position (was offset by 4 mm)
- Rename silkscreen labels from axis 1..4 to join 0..3 to match riocore/LinuxCNC convention
v1.0
Initial released version.

Questions
How big is the Rioctrl quadenc4 PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rioctrl quadenc4 use?
121 parts, built around the CS48505S, USBLC6-4SC6, BSD5C031V and UPZ1608E101-3R0TF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Rioctrl quadenc4 KiCad files?
From the festlv/rioctrl-hw repository on GitHub, at the commit this page was made from: the board is rioctrl-quadenc4/rioctrl-quadenc4.kicad_pcb and its schematic breakouts/ditron-dc11-encoder/ditron-dc11-encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rioctrl quadenc4 design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
