Fred <micowave@clix.pt>  from Azores islands, Portugal. offer PCB layout for both V3.X and V4.X.

Here is the V4.X . Download lay file DST_Fr88.zip

A 75 x 50 mm PCB, design by Glatt Wastl from the Bavarian Alps.
fit the dimensions of the LCD module, pins to holes.

Thank you, Glatt Wastl !

Hardware V1.6

================================================

Multi-Tester V4.35 Spec:

Tachometer :

   Non-contact Digital Photo Tachometer


Servo tester:
 
    Resolution 10 uS / step, 20mS / frame 


    6 test modes:

1. Manual mode
The PWM pulse width range from 1000uS~ 2000uS, 10uS/step with one touch neutral point (1500uS).

2 Knob
Analog knob input, around 850uS ~ 2150uS

3. Fast mode
Jump between 1000 and 2000 every 0.5 second, auto process 5 times 

4. Middle mode 
2 second from side to side, auto process 5 times 

5. Slow mode
10 second from side to side, auto process 2 times 

6. Random mode 
Random Jump every 0.3 second, auto process 20~30 times 


Speed controller tester:


     2 test modes:

1. Manual mode
The PWM pulse width range from 1000uS~ 2000uS, 10uS/step with one-touch stop point (1000uS).

2 Knob
Analog knob input, around 850uS ~ 2150uS,  depend  

 

Receiver tester:

    Measure Range  0.80mS ~ 2.20mS PWM

Voltmeter:

    DC 0~20.0V / resolution 0.1V

================================================

FAQ:

1. What the purpose of the LED ?

    The LED is indicator of Vcc Out to servo,

2. I notice the 2SA684 doesn't turn ON in Tacho mode. Could the 2SA684 be program to turn on during Tacho mode or Receiver mode?

   This could be useful when testing small park receiver like GWS nano or pico receiver.   

   If you need to power receiver, just add one more 3-pin connector, with the pin2 connect to Vcc through one diode (like the V3.X version) , or eliminate the 2SA468, at all
