Overview
ChickBoard is an open-source printed circuit board by tbowmo, from the tbowmo/ChickBoard repository on GitHub. It is a 2-layer board of 50 × 30 mm with 36 parts on 51 nets, routed with 53 tracks and 0 vias.
It is built around the SN65HVD485EP and AMS1117. Its parts include 12 connectors, 9 capacitors, 5 ICs, 4 resistors and 2 diodes. It belongs with the SAM D and SAM boards of this library.

A little background info: The plan is that all birds in our chicken coop have a RFID tag (using 125Khz TK4100 tags). Each nest then have an EM4100 RFID reader module, so I can follow the birds between all nests.
Because the nests are not placed near each other, I have settled on RS485 for nest communication. It's also planned to have a LED strip or two in the ceiling, to give a little light in the dark winter nights.
This board is meant as a multipurpose board for this project, so it can be used in a couple of different situations:
- RFID reader (EM4100)
- 1wire bus (can be used with DS1820 to measure temperature)
- 2 x LED drivers (fet transistors)
- RS485 bus for communication
- Atmel ATSAMD20 (upto 256Kb flash)
- MYSX 2.2 board extension board connector

Questions
How big is the ChickBoard PCB?
It measures 50 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ChickBoard use?
36 parts, built around the SN65HVD485EP and AMS1117. 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 ChickBoard KiCad files?
From the tbowmo/ChickBoard repository on GitHub, at the commit this page was made from: the board is ChickBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChickBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask tbowmo before reusing the design.
