 EQ Track hardware is composed of two parts :

 * The main controller, which was built around a PIC16F876A ; any compatible recent Microchip PIC can be used. The main controller is connected to :
+    * The 12 V DC power supply (VCC and Ground),
+    * The two stepper motors (2 x 4 phases + Ground), either unipolar or bipolar,
+    * The keypad, through a 3 wire interface (5 V, Ground, Data).
+* The keypad, which was built around a PIC16F628, any compatible recent Microchip PIC can be used. The keypad is only connected to the main controller, and uses 4 buttons and 3 switches to control the system.

 In either case, the rotation sense can be reversed by swapping pins 1 and 2 (or 3 and 4) in right ascension, 5 and 6 (or 7 and 8) in declination.

-##User manual##
-
-Once everything is built and connected, you can start using EQ Track basic.
-
-####Power on####
-Just apply 12 V power to the *RED* and *BLACK* connectors of the main controller. The buzzer emits a single long beep, the LED starts flashing at one second intervals and the right ascension motor begins rotating.
-
-####Monitoring####
-When the power supply voltage is above 11.5 V, the LED flashes green ; when it drops below 11.5 V, the buzzer emits a double beep, and the LED starts flashing amber ; finally, when it drops below 11 V, the buzzer emits again a double beep, and the LED starts flashing red... and the battery won't last long after that.
-
-####Tracking, guiding####
-The tracking rate of the right ascension motor can be set to *Sidereal*, *Solar*, *Lunar*, or *User* tracking rate, with the *RATE* switch.
-
-Using the keypad *North*, *South*, *East*, *West* buttons, you can slew in the corresponding direction.
-The slew speed is controlled by the *FAST* switch :
-
-* at off ("slow") position,
-
-    * the right ascension motor slow or accelerate at 20% of the tracking rate,
-    * the declination motor rotate at slow speed,
-
-* at on ("fast") position, the right ascension and declination motors rotate at maximum speed.
-
-####Settings####
-The *SETTINGS* switch allows to change parameters, depending on the switch position :
-
-* Position 1, "Normal" :
-    * No parameter can be set, the system perform its operational function.
-* Position 2, "Right ascension, slow" :
-    * *North* or *South* button increments the power of the right ascension motor at tracking speed ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
-    * The rotation sense can be inverted by pressing *North* or *South* during more than one second.
-    * *East* and *West* buttons decrement and increment the selected tracking speed by,
-        * 1 % when the *FAST* switch is on,
-        * 1 ‰ when the *FAST* switch is off.
-* Position 3, "Right ascension, fast" :
-    * *North* or *South* button increments the power of the right ascension motor at fast rate ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
-    * *East* and *West* buttons decrement and increment the fast rotation rate of the right ascension motor.
-* Position 4, "Declination, slow" :
-    * *North* or *South* button increments the power of the declination motor at slow speed ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
-    * *East* and *West* buttons decrement and increment the slow rotation rate of the declination motor.
-* Position 5, "Declination, fast" :
-    * *North* or *South* button increments the power of the declination motor at fast speed ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
-    * *East* and *West* buttons decrement and increment the fast rotation rate of the declination motor.
-
-When a setting is changed, it is permanently saved after one minute without further modification.
-
-Whatever the setting switch position, all settings can be reset to their factory value by pressing *East* and *West* buttons simultaneously during more than one second.
+Once everything is built and connected, you can start using EQ Track basic. The [User manual](../Basic-UserManual) page explains how to use the keypad.
