Door Controller Panel
The Ozeki Door Controller Panel is capable to recognise RFID tags to control doors. You can also connect an LCD display and a 12 button keypad to it. If you would like to control a doorbell, you can control it with 433 MHz radio frequency signals. To see how a Door Controller Panel works you can build a Door Controller Matrix from the necessary Ozeki Modules:
Figure 1 - The modules that need to be connected to create a Door Controller Matrix
These Ozeki modules are connected to eachother to create a Door Controller Matrix (Figure 1):
When the modules are attached to eachother they look like this:
Figure 2 - This how the assembled Door Controller Matrix looks like
The programmable modules are the Ozeki NFC Host, Ozeki 433Mhz RF Module, Ozeki Display Module and Ozeki Relay Module. Each contain an Atmega 328p microcontroller so you can program them separetly like an Arduino Nano using the Arduino IDE environment. But you should be aware that not every pin is led out from the 328p chips so they have less pinouts then an Arduino Nano. As a reference you can check out the Arduino Nano specifications. A reset button can also be found on each module just like on the Arduino Nano.
Each programmable module connects to PC via seperate USB to serial converter chips (CH340G). But physically this is just one micro USB cable. The same that is used for connecting smartphones and PCs.
Ozeki Door Controller on a single PCB
Instead of connecting the 6 modules, you can have the whole door controller on a single PCB. Below we have provided the download files for manufacturing. If you decide later on that you would like to build something else, you can always cut the panel and create seperate modules.
