 +
 +
 +** THE ASSEMBLY IS TERMINATED FOR THE MINIMUM VERSION OF THE CARD. NOW WE ARE GOING TO START THE OPTIONAL PARTS.  QR:THE CONNECTOR 2 × 20 pins OF THE RASPBERRY PI WILL BE WELD IN THE LAST TIME. IF YOU USE ONLY THE RELAY VERSION WITHOUT LINK, THIS PART MAY BE NOT WELDED.**
 +
 +
 +**4. OPTO INPUTS assy**
 +
 +{{:documents:optoinput.jpeg?500|}}
 +
 +{{:documents:optozoom.jpeg?500|}}
 +
 +The components list to be installed:
 +  * **R33 à R36** 220 Ω (This value can be changed according to the input voltage. Here it's for 5V)

 +  * **R37 to R40** 10 kΩ
 +
 +**5. WATCHDOG assy**
 +
 +{{:documents:watchdohzoom.jpg?300|Watchdog détails}}
 +
 +The components list to be installed:
 +  * **IC5** MAX6369
 +  * **C14** Capacitor 0,1μF
 +  * **PIN 2x1** Weld the 2 connectors. One is useful to activate the Watchdog and the other (RUN) to connect the RUN or P6 connector of release (Reset) of the Raspberry Pi. SET0 SET1 SET2 are jumpers (solder) to determine the time before reset if it does not send a signal. 
 +
 +A Watchdog "MAX6369" is a standalone CI. If the component does not receive a voltage pulse (System crash) in a defined period, it will reset the system.
 +
 +{{:documents:watchdogdetail.png?700|}}
 +
 +{{:documents:max6369-max6374-3.pdf|Datasheet:MAX6369-MAX6374.pdf}}
 +
 +As boot starting time exceeds 10 seconds, it is recommended to set the detection time (timeout) at maximum. As indicated in the above table, the 3 jumpers SET0, SET1 and SET2 needs to be closed (Weld the three pairs of squares).
