Hallo an alle,

(Entschuldigung für die Übersetzung, aber ich bin durch Google gegangen)

Ich beglückwünsche den Schöpfer dieses Mähroboters zu all seiner Arbeit.
Ich beendete die Montage einer PCB 1.3 mit Komponenten, die auf der Site Marotronics gekauft wurden.

Ich habe die Videos zum Bearbeiten verfolgt. Am Ende der Bearbeitung habe ich nicht die gleichen LEDs auf Video 7, die sich einschalten.
Ich habe die 24-V-LED und die buzzer-LED und den buzzer blinken (1 Mal lang und zweimal kurz und es beginnt wieder).

Ich fürchte, ich habe einen Fehler gemacht. Könnten Sie mir helfen?

Danke, Nico.

Hello,

I hope you could already solve your problem, if not, can it be that you've already flashed the arduino with the software?

Hello
for the last test video
All lights are fine, except + 3.3V and + 5V
And on the KINGBRINGT only 24 V

Can you help me?
thank you

What about:
JP1
Smd Fuse
9V

 

[yaya]

JP1 is ON
F1 Smd is OK
9V is OK

 

[yaya]

but i have on "Power DUE Arduino"
for 5v only 1,21 V
and
for 3,3V only 0,44 V

 

[bernard]

9V is OK on the output of DC/DC i suppose ?
Have you the 9V on PCB1.3 Vin of the Arduino (With and Without the DUE)
Try to connect on table Only the Vin and GND with wire from PCB1.3 to DUE and check 3.3 and 5 V on due

JP8 Always ON ?

 

[thorsten-ac]

hi, have you set the dc dc converter correctly?

Thorsten

 

[yaya]

DC/DC 9V ok ( photo )
JP8 is ON
Vin 8,42V without the DUE card is 8.69V
3.3 V With card is 0.44V without 0V
5 V With card 1.21 V without 0V
my battery may not be charged enough ...

The 3.3 and 5v is normal 0 without due but it is not exactly what i want to know.
Remove the due from the pcb.
Use wire to connect vin and ground from pcb to due
And check the 5 and 3.3 on the due output.

It is to check the due dc/dc stepdown.
Normaly i will be ok.
Certainly a shortcut or capacitor or diode in wrong way on the pcb
Check them again or send zoom picture of different parts of the pcb

Test without all the other component motor driver led rtc etc
For the battery if it is more than 24V when all is on it is ok

 

[yaya]

the DUE Input
VIn GND : 8.44 V

the DUE OutPut
3.3 V always 0.44V
5 V always 1.21 V

Best regard

[bernard]

What is the 3.3V and 5V of the Due when powered using PC USB ?
If it's not 5V and 3.3V Certainly DC/DC step down of the Due is dead.
Maybe a shortcut on the board when soldering or diode inversion.

 

[yaya]

3,3 V OK
5 V OK
With PC USB

[bernard]

If you have 9V accu test this

[yaya]

Allways the same problem
Best regard

 

[yaya]

the arduino forum is talking about a manufacturing problem. the R28 resistance of 10k has been replaced by 100k with output voltage problems. https://forum.arduino.cc/index.php?topic=551534.0
Do you think that feeding the DUE card differently.This could work?

best regard

 

[bernard]

Certainly your Due is dead.
You need to have 5V and 3.3V on the output of the Due when power it using Vin.

If you have only plug the Due to the PCB1.3 check for PCB shortcut before testing a new one.

[yaya]

it does not work

I was offered to connect the DUE card via USB (5V) on the battery, what do you think? see the photo

[bernard]

Normaly when you test the system the DUE is powered by the PC USB (to see the console).
So if it did not work like that it is dead
Try to check the resistor (Why not ?)

Using the external 5 Volts certainly change all the Analog accuracy and it's better to avoid.

 

[yaya]

I exchanged the DUE card now it's OK
thank you for everything
