Adafruit Universal USB / DC / Solar LiPo Charger and The Micro:Bit

Hi,

I have just spotted the subject product on the PiMoroni Web Site and had a question.
This Solar Charger
Could I use this the power out socket to power a Kitronic MicroBit Motor Driver Board?

Every year at school I get the Year 6 children to work towards a STEM Robotics competition, building a wooden chassis for a MicroBit powered buggy to enter in a couple of challenges. One is along the lines of PiWars PiNoon (burst your opponents balloon). At school, we have just embarked on a sustainability venture, so I would like to add an element of renewable energy in this project, so using solar power either for powering the buggies, or at least charging thier rechargeable batteries (I normally use 4 x AA Alkaline Batteries).

Thanks

Any comments / help with this would be appreciated :-)

Looks like it should work - the LOAD OUTPUT connector on the charger board puts out 4.4V max and the input on the Kitronik motor driver can deal with voltages between 3V and 10.8V.

Note that you shouldn’t connect the charger directly to the micro:bit though, as the battery connector is 3.6V max.
