So this question might sound a bit weird since I'm pretty new to programing development boards. What I need is a board that can be powered using a battery and that also supports Bluetooth. I'm interested in the Arduino Blend Micro(https://store.arduino.cc/blend-micro), how do I know if this boards supports the usage of batteries?

It would be even greater if the board would charge its battery when connected to a power source via USB. However I have no idea what this concept is called, nor do I know how to search for a board online that supports this feature.

    \$\begingroup\$ a board that can be charged using a battery In general boards cannot be charged. Perhaps what you mean is "a board which can be powered by a battery. In principle all boards can be powered by a battery". Almost all Arduino based boards can be battery powered (they do not consume much power) as long as you supply the board with the right voltage. The Arduino board does not and cannot "know" the difference between being battery powered or from an adapter. So you will not find in the description if a board can be powered from a battery as in principle all can be. \$\endgroup\$ – Bimpelrekkie Aug 20 '17 at 10:51
  • \$\begingroup\$ if the board would charge its battery Show us a board which has a battery which needs charging. All the Arduino boards I know do not have a battery and therefore cannot and do not need to be charged. \$\endgroup\$ – Bimpelrekkie Aug 20 '17 at 10:54
  • \$\begingroup\$ I would add the bettery myself and connect it to the board, so the board gets powered by the battery. And when the board gets connected to a power source via its USB port, I want to know if this power could be used for charging the battery. \$\endgroup\$ – Jannis Aug 20 '17 at 11:01
  • \$\begingroup\$ Basically the same concept with a phone, you can charge it's battery by using its USB port. \$\endgroup\$ – Jannis Aug 20 '17 at 11:02

\$\begingroup\$

Any board can be run with batteries if you match the voltage and current needed by the board.

For boards that can recharge batteries, you would look for boards with built in lithium or other battery type charger circuits. There are some arduino type boards with this built in, but there are also modules you can buy to connect.

As a kludge, you can just use a usb battery pack. Built in battery and charging and voltage regulation.

  • \$\begingroup\$ Yes - however very few development boards can be used to obtain long standby (let alone) lifetime on battery, as that requires design details that typically aren't part of development board goals - the exception would be boards specifically designed to demonstrate long battery lifetime. \$\endgroup\$ – Chris Stratton Aug 20 '17 at 18:51
  • \$\begingroup\$ @Chris sure, if you need ultra long life and not just portability. \$\endgroup\$ – Passerby Aug 20 '17 at 18:59
  • \$\begingroup\$ It's not so much a question of "ultra long life" as if the application is one where the user can physically disconnect the power whenever it is not actively needed - without that, a set of batteries is likely to last no more than say 3 days, or for some projects only a few hours. \$\endgroup\$ – Chris Stratton Aug 20 '17 at 19:06
