Qduino Mini-specific technical information

Development Boards Arduino
1

Hello

I’m trying to look through technical resources and tutorials linked to Qduino Mini product page and all of them seem to be dedicated to using this board as just another Arduino. That’s fine, but I need more specific information, specific to this board that is. If I understood it correctly, this board is deliberately designed to run on battery power and provide automatic charging capabilities when the board is connected to external power. So, what I’d like to know, for example:

  1. I see that SparkFun Qduino Mini product page also links to a 1Ah and 110mAh LiPo cells. So, what would be the expected/average run time for this board on a 110 mAh cell? Any laboratory tests available? Real-life feedback?

  2. How do I determine from inside the software whether the board is currently running on external power or has switched to a LiPo cell? Is there a software-accessible indicator?

  3. Where can I find Qduino Mini technical resources describing such matters?

Thank you

Thanks for reaching out to us on this.

Please reference the datasheet found at: https://cdn.sparkfun.com/datasheets/Dev … MiniV1.pdf

1. I see that SparkFun Qduino Mini product page also links to a 1Ah and 110mAh LiPo cells. So, what would be the expected/average run time for this board on a 110 mAh cell? Any laboratory tests available? Real-life feedback?

That depends on manifold factors, such as duty cycle, current draw by the system, temperature, humidity, etc…we cannot offer an estimate on run-times for specific use-cases, as they are inherently so specific. The 1Ah cell would provide ~9x more run-time than the 110mAh.

2. How do I determine from inside the software whether the board is currently running on external power or has switched to a LiPo cell? Is there a software-accessible indicator?

Please refer to the product’s hookup guide, where this and many other relevant topics are covered: https://www.hackster.io/team-qtechknow/ … _&offset=0
