Fire Bird V ATMEGA2560 Hardware Manual
Connecting Fire Bird V robot board to bigger robot
L293D motor drivers on the main board can only provide current up to 600mA per motor. If you
want to drive bigger robot using Fire Bird V main board then remove L293D motor drivers from
their IC sockets. You can interface high power motor drivers such as Hercules or Hercules lite
from NEX Robotics which can drive motors up to 36V and 30Amps to the external motor
interface ports. Location of L293D ICs is shown in figure 3.18 and External Motor Interface port
1 and External Motor Interface Port 2 in figure 3.21.

Important:
Give high current power supply to the motor drivers directly without going through Fire Bird V's
main board and make sure that Robot's ground and motor driver's ground are common.
