EtherPort Data Acquisition & Control System EtherPort DOUT 48-Channel
with Robotdyn W5500 Ethernet module
4
Project description
The EtherPort DOUT board is a 48-channel digital input board. The EtherPort DOUT offers the following features:
- Open Source/Open Hardware design (Creative Commons 4.0 license)
- Single 5V power supply
- LED indicates when power is applied
- 48 independent output bits (TTL 5v outputs)
- 48 output pins divided up into 4 banks of 12 bits each
- Optional DIN rail brackets allow installation on 35mm DIN rails
- DIN rail brackets are available in .STL format for 3D-printing
- Full documentation including System Requirements Specifications (SyRS), Hardware Requirements Specifications (HRS), Hardware Inspection list (HI), Hardware Test Cases (HTC), Hardware Test Procedures (HTP), Hardware Design Description (HDD), and (reverse) Traceability Matrix (RTM) are available for the EtherPort system, including this board.

PCB Availability and Files
Note: If you only want a few EtherPort DOUT PCBs, contact Plantation Productions (randy@plantation-productions.com) to see if there are any in stock. Bare boards are $20 each plus shipping; fully assembled and tested boards are $499 each. If you need more than a couple PCBs and you're not in a huge hurry, it costs about $50 (plus about 4-6 weeks) plus shipping to have a set of 10 manufactured and shipped to you from China. I use Seeed Studio Fusion PCD service (https://www.seeedstudio.com/fusion.html). The EtherPort DOUT PCBs are two-layer boards.
