+ | ====== Description. ====== | ||
+ | {{ : | ||
+ | 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# ^ Function | ||
+ | | 1 | Ground | ||
+ | | 2 | + 5 Volt | | | | ||
+ | | 3 | Non Inverse output | ||
+ | | 3 | Inverse output (R2 + R6 installed) \\ R6 only if 3.3 V output is required | ||

+ | ^ Connection with GCA_PI01 S1 ^^^^ | ||
+ | ^ GCA_RFID J1 ^ GCA_PI01 S1 ^ Function | ||

+ | ===== Important Note: ===== | ||
+ | | ||
+ | For use with GCA_PI01 or Rasberry direct | ||
+ | - Do NOT mount R3. | ||
+ | - Mount R6 (2.2 KOhm) | ||
