Powering NanoPi M1 via External Battery

[bkaankuguoglu]

Hi, I've just received my NanoPi M1 and I'm currently working on a project that involves measuring temperature, humidity, moisture and sunlight via sensors. Since I'm planning to place my pi outside, I'm looking for a solution to power my device.

First of all, how strict is 5V rule for NanoPi M1? From my earlier experiences, some devices may have some tolerance when it comes to Voltage, e.g. Particle Photon works perfectly between 3.6-5.2V.

Secondly, how do you connect your power source without using mini usb port? Can you show me an example of how to add an external battery to the circuit, feel free to use the image below?



Lastly, I'm so confused with the ports/pins on the board. I have literally no idea how I plug my sensors into these ports. Each sensor have sig, vcc, nc, and gnd pins, and it is not very clear how to use them, in the code.

Thanks heaps in advance. Have a good one!

The M1 product page has the GPIO Pin Spec at bottom:
http://www.friendlyarm.com/index.php?route=product/product&product_id=109

There are 8 GND pins, two 3.3V pins and two 5V pins on GPIO.

You can power the M1 over GND/5V pins from Debug UART as well (3.3V is definitely not enough to power even my Neo).
I did so for the NanoPi Neo, do not have a M1 yet.


This link from Jim's list shows how to connect S/V/G of sensor with GPIO pins, see "Connection Details":

If you're familiar with WiringPI library you can use WiringNP https://github.com/wertyzp/WiringNP library

Why is ISR not implemented in WiringNP?
