See the drive datasheet: (URL) can reach 1A peak, continuous value is lower (500-600mA) especially if both outputs are heavily loaded at the same time.

Now you can use your RCX to control LEGO Power Functions. That's right the RCX can act as a PF remote control but it can do something that the PF remote can't do yet. The RCX can do PWM with your PF reciever moduals. You do not need to install (...) (17 years ago, 25-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, lugnet.announce, FTX) !
