to power an external sensor I need 5V or 24V (a few current , max 10ma).
Is there a point in namino where I can hook up?
how can I do?
1)If I use an digital out to produce a +24V I still need an external voltage …
2)Vcc of J3 is it usable? ( To have 5V is necessary 5V jumper? )
So the same trick is possible to generate a 5V for +Vpot?
To power an external sensor you have a few choices:
- use pin 3.3V or 5V on ROSSO or ARANCIO board (J7 side A);
- use Vcc on J3 (remember to close the jumper with the required voltage: 3.3V or 5V)
- use the digital outputs
The digital outputs are driven at +Vp or 3.3V (chosen with J9)
+Vp (voltage driven by an external power supply) can be between 5V and 24V.
Using +Vp, the voltage of the digital outputs at logic level 1 is +Vp, therefore it is possible to drive and power the sensors with these digital outputs.
about J9 jumper position to " dig out power config".
- Jumper : center to ext-board= + Vpot
- Jumper : center to internal-board = +3.3V
Is corret? or inverted?
