Description: This RFID Access Control Shield transforms your Arduino to an access control device. It comes with ID-3LA Reader Module presoldered on to the shield. This shield includes almost everything that an access control system requires. Onboard Relay driving circuitry helps your Arduino to control magnetic locks, solenoid valve etc. The 5V buzzer provided on board can be used for indicating the RFID card acceptance, say single beep for card acceptance and double beep for rejection.
Relay pins are available on a 3-pin screw terminal (NO,NC,COM) along with a 2-pin screw terminal for powering the 12V relay. Three LEDs are provided on board; STS, RLY and PWR. PWR indicates the power while RLY indicates relay actuation. STS comes in direct connection with an Arduino pin (D12) and it can be controlled in accordance with your Arduino sketch.
The shield is provided with an on board DPDT sliding switch which helps you to connect the RFID module either to your PC (via Arduino USB) or to your Arduino itself. This feature helps you to configure/test the RFID module before actually using it in your project, this eliminates the need for any separate RFID development board. In addition there are two onboard switches enhancing its features. SW1 can be used to reset your arduino board. Whereas, SW2 is a programmable switch that comes in connection with arduino pin (D10). Shield also comes with a couple of jumper connections for easy adaptation.

Function |
| J1 |
Enables/Disables Buzzer |
| J2 |
TX Voltage Divider (short if used with 3V3 Arduino Boards) |
| J3,J4 |
Selects between hardware UART and software UART |
| J5 |
RX Voltage Divider (short if used with 3V3 Arduino Boards) |
| J6 |
Switches Buzzer between Arduino & Module |
| J8 |
Output format selection (Serial ASCII: Strap to GND, WEIGAND 26: Strap to +5V) |
Switching buzzer to module (using jumper J6) automatically triggers the buzzer whenever a RFID tag is read by the reader. The shield does come with headers pre-installed, just plug it and your arduino is ready to read RFID tags. Do burn a proper sketch before trying to read any tags ;)
Note: If you are using multiple shields, make sure this shield stays on top of all others. ID-3LA requires external antenna, datasheet has detailed explanation on antenna design.
