The Red Dragon 1 can be used as a stand alone motor driver without either the Picaxe chip or the RF remote board. 2 L293D chips can control 4 motors (to about 1 amp limit), forward and
reverse with 8 digital control inputs. Put positive voltage on motor #1
forward connection and the motor goes forward. Please note the output
voltage to the motor will be about 3/4 the supply voltage. So an 8 volt
supply would be about 6 volts at the motor when it is activated. This
kit will require soldering, sample wiring diagrams are included.

Red Dragon 1 circuit board.
The Red Dragon 1 board is a PICAXE 18M2 PC
programmable microcomputer with onboard memory for 1800 lines of code. 2
motor driver chips you to have 4 motors under program control forward
and reverse. The board has contacts designed to solder on inexpensive 4
& 6 channel RF remote control receiver boards. You then use the
small remotes press a button they will be detected on PICAXE pins and
can be used live under program control. I include the full specs of the
board so you can experiment beon the motor driver and build a full
system if you wish.
This kit only includes the motor driver parts of the
board and a guide on how to tap into just the motor driver outputs and
input signal lines. You do not need the PICAXE chip or a remote receiver
board to use just motor driver. Please note that control inputs for
motors #1 and #2 are at the PICAXE chip socket pins. Control inputs for
the motors #3 and #4 are the 4 pin header connections along the edge of
the board. If you only wish to control one motor you can omit one of the
L293D chips.
