When I connect the Raspberry Pi to my Nybble and walk it, the Raspberry Pi is easy to reset. Please tell me how to improve it.I dial the potentiometer clockwise to get the lowest voltage to the servo. And I use the following lithium polymer battery.
Turnigy nano-tech 2000mAh 2S (2cell / 7.4V) 20 ~ 40C
200g should be ok.
Is there a problem when powering the mobile battery from Micro USB with NyBoard and Raspberry Pi connected? If I power the Raspberry Pi from NyBoard and Micro USB at the same time, will the Raspberry Pi be damaged?
@Taka I recently asked a similar question. It turns out, the Pi and chip will get a steady 5v as the Nyboard has on-board power management. I've been running mine on a 9v Lithium Ion and so far haven't had any issues, but my servos may be running a touch faster.
@Taka I missed your question last time. It should be safe. I actually have tried it before to make the battery run longer. But I recommend using one power source at one time.
The key parameter is the voltage and continuous discharging rate. The recommended voltage should be <8.4V, and discharging current should be >3A.
I understand. Nybble and Raspberry Pi are not connected, and I am planning to power the Raspberry Pi from a mobile battery. And I want to have a pi camera on my Raspberry Pi. In that case, how much weight can I put on Nybble's back?
No, too high voltage will damage the servos. You can actually try some lower voltage but with larger C rate(discharging rate)
Thank you very much! I will think about it.
I am thinking of powering the Raspberry Pi from a mobile battery. I want to put a 180g mobile battery on top of a Raspberry Pi. In this case, is it likely that a servo trouble will occur?
If you are using the NyBoard V0_2, you can connect the jumper switch SW3 between BATT and V_S. The potentiometer will be bypassed to provide the unlimited power. The bottleneck will then be the battery.
Thank you for your immediate response.
Currently I have such a connection.
Will it improve if I use a higher voltage (eg 9v) battery?
