How should I drive this pump from a microcontroller?
A microcontroller pin usually cannot supply pump current directly. Switch the pump with a MOSFET or transistor, with the pump powered from a separate 3.7V supply and a common ground.
Can I run it from a single 3.7V Li-ion cell?
Yes, a single 3.7V Li-ion cell matches the pump's rated voltage. Make sure the cell can supply the pump's current and use a protection board to prevent over-discharge.
