 +====== Description. ======
 +{{  :​gca:​gca_rfid_pict_02.jpg}}
 +For ID-12 and ID-20 RFID sensors, it would be nice to have some kind of mounting board.\\
 +This avoids soldering on the rather expensive unit itself, it takes care for various \\
 +connections between pins, and also provides the needed place for resistors and capacitor.\\
 +This newest version also provides an extra resistor, in case the RFID sensor is be used to connect\\ ​
 +with 3,3 V systems like Raspberry Pi and the GCA-PI01 HAT.\\
 +The numbers with connections correspondend with the numbering on GCA_PI01 S1 connector.\\
 +Remind that only pin 1,2 and 4 are to be connected to GCA_PI01, do NOT connected pin 3 in this case.\\
 +ID-12 and ID-20 also provide INVERSE(3)(=connection to any Processor) and NOT INVERSE(4)(= connection to RS232 port) outputs.\\
 +Follow directions below in case you have some doubts.\\
 +To avoid unstable situations a led indicator on this board is charged by a transistor, and\\
 +a small filter (R1 and C1) is used in the power supply.\\

 +===== Pin connections =====
 +^  Pin#  ^  Function ​ ^  Remark 1  ^  Remark 2  ^  ​
 +|  1  |  Ground ​ |  |  |  ​
 +|  2  |  + 5 Volt  |  |  |  ​
 +|  3  |  Non Inverse output ​ (R3 installed) ​ |  remove R2 and R6  |  This option is for direct connection to Serial Port.  |
 +|  3  |  Inverse output (R2 + R6 installed) \\  R6 only if 3.3 V output is required ​ |  remove R3  |  Direct connection to any processor ​ |

 +^  Connection with GCA_PI01 S1  ^^^^
 +^  GCA_RFID J1  ^  GCA_PI01 S1  ^  Function ​ ^  Remark ​ ^
 +|  Pin 1  |  Pin 2  |  GND  |  **Please note pin reversal !**  |
 +|  Pin 2  |  Pin 1  |  +5V  |  **Please note pin reversal !**  |
 +|  Pin 3  |  Pin 4  |  Signal ​ |  R3 NOT installed ​ |

 +^  Connection with CAN-GC4 ​ ^^^^
 +^  GCA_RFID J1  ^  CAN-GC4 ​ ^  Function ​ ^  Remark ​ ^
 +|  Pin 1  |  Pin 1  |  GND  |    |
 +|  Pin 2  |  Pin 2  |  +5V  |    |

 +===== Important Note:  =====
 +  ​
 +For use with GCA_PI01 or Rasberry direct ​ (= 3,3 Volt situation):​\\
 +  - Do NOT mount R3.
 +  - Mount R6  (2.2 KOhm)
