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 shiftio PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rioctrl shiftio use?
141 parts, built around the ELQ3H4(TA)-G, 74HC165D,653-JSM, 74HC595D,118 and 1N4007WS. 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 shiftio KiCad files?
From the festlv/rioctrl-hw repository on GitHub, at the commit this page was made from: the board is rioctrl-shiftio/rioctrl-shiftio.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 shiftio 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).
