Uln2003 Kullanımı. Ti alldatasheet datasheet datasheet search site for electronic components and semiconductors integrated. With nothing special in mind other than curiosity i bought one and had a quick play with it using the standard arduino stepper library.
Free delivery on orders over 40. Well you can get up to 250ma per channel if four of the seven. Four out of seven pairs are used on this board.
It has the capacity to drive 500ma into a single channel but wait it doesnt mean you can get 500ma on all the seven channels when all the seven channels are active.
Relay driver ic uln2003 is high voltage and high current integrated ic which used darlington array. Improved thermal dissipation and energy efficiency for peripheral driving. The 28byj 48 motor is a 4 phase 8 beat motor geared down by a factor of 68. It has the capacity to drive 500ma into a single channel but wait it doesnt mean you can get 500ma on all the seven channels when all the seven channels are active.
