-====== Door Controller V2 ======
+See [[door_access_controllers]].
-===== Component Overview =====
-  * Controller: Enclosure, PCB inc ESP8266, LED, push-button
-  * Reader: PN532 module, laser-cut case, LED, piezo disc
-  * Door Hardware: electric release, magnetic door-closed sensor, optional exit button/sensor
-  * Software: ESP8266 [[https://github.com/timhawes/or2_firmware|firmware]], Python server application

-===== Reader =====
-CAD files: {{:nfc-reader-20160626.dwg|DWG}} {{:nfc-reader-20160626.dxf|DXF}}
-Components:
-  * 3mm blue LED
-  * 120R resistor (this is low, but an additional resistor is used on the controller PCB)
-  * [[http://uk.farnell.com/multicomp/mcabt-456-rc/audio-element-piezo-9-5khz-12mm/dp/2433032|12mm piezo disc]]
-  * [[http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_93&products_id=2242|PN532 module]]
-  * Cat 5 or other cable with at least 7 cores
-The reader enclosure is formed from three layers of 3mm black acrylic. The layers should be joined with cyanoacrylate adhesive.
-Configure the PN532 module to use I2C communications.
-Bend and cut the LED leads to the correct shape and length. Solder the LED and cable before gluing the module into the enclosure.
-Cat 5 cable colours:
-| blue | GND |
-| green | VCC |
-| brown | RST |
-| orange | SDA |
-| white-green | SCL |
-| white-brown | LED +ve |
-| white-blue | Piezo |
-| white-orange | not used |
-Note that on the G11 door and **in the photos**, orange=VCC and green=SDA.
-The LED should be connected between white-brown and GND (blue), with a 120R series resistor. To avoid damaging the LED, use hot-melt glue to secure it in place (not cyanoacrylate).
-The piezo should be connected between white-blue and VCC (green). The piezo may be secured with cyanoacrylate or hot-melt glue, but try to give the disc some freedom of movement or the sound output may be reduced.
-Test the reader and controller together before securing the reader to the wall with double-sided adhesive foam tape.
