Ardumower Perimeter sender V2.00

[walter]

Hi,

Here is a preview of the new perimeter sender V2.0

Once approved by the software developers i will upload the layout to the Download section

Features:

- uses the MC33962 dual H-bridge module (available in the ardumower shop)
- Arduino Nano V3 ((available in the ardumower shop)
- can be switched by a jumper to perimeter V1.00 or the new V2.00 signals
- Can by setup to have 2 fully separated perimeter loops or to a double "current" perimeter loop
(for very long perimeter wire)

Any error reports are welcome

Walter

Is it possible to include, maybe by a jumper, a China-LM2596-PCB on your PCB?

Hi

Why do you want to add a LM2596 circuit to the PCB ?

The H-bridge module and arduino-nano have its own 5V regulators onboard

Is it possible to include, maybe by a jumper, a China-LM2596-PCB on your PCB?

Oh, yes you are right

But when you want connect a higher voltage than 5V you need a voltage regulator. I think it is nessary for V2, that we have a higher voltage.

Hi male1337

You can connect to Vin (h-bridge) any voltage you want up to 28V
internaly the arduino nano has a 5V regulator which goes to VDD of the h-bridge module

So there should be no problem if you use a higher voltage

Ofcourse we need to build a first prototype to test everything

But when you want connect a higher voltage than 5V you need a voltage regulator. I think it is nessary for V2, that we have a higher voltage.

OK, you know it better I have ever think Arduino Atmega based 5V on VIN.
Datasheet for NANO:
Input Voltage (recommended) 7-12 V
Input Voltage (limits) 6-20 V

Dear All,
perimeter wire tested...When I came back to the work, I will try also the oscilloscope...

bye

Hi Fabio

Did you made the perimeter V2 PCB ?

I made the PCB layout, but never build one untill now

Looking forward

ps: Sei Italiano ?

 

[sigismondi]

For the perimeter sender I used a copper holed plate..not a PCB (is faster for short circuit) and I didn't find the library of the L298N motor driver for fritzing (a PCB software maker)....

Si sono italiano...per messaggi...scrivimi in privato in italiano..grazie ciao

@ Walter

can you add the Potentiometer to your PCB please and add it to the Wiki ?

Thanks Stefan
