Deluxe Receiver
Sound & Recording IC
The Deluxe Receiver module (only in SCROV-50
Deluxe Snap Rover) is a combination of the RX1
R/C Receiver and U8 Motor Control IC modules
shown on the preceding page. These modules
were combined in one package to make room on
the base grid for for additional modules in Deluxe
Snap Rover. The schematic looks like this:
The Sound & Recording IC module (only in
SCROV-50 Deluxe Snap Rover) contains an integrated recording circuit, a dual timer integrated
circuit for making audio tones, microphone,
speaker, filtering circuitry, and other supporting
components including 24 resistors (2 are
adjustable), 13 capacitors, 3 transistors and 4
diodes. Its schematic looks like this:

The Disc Launcher unit (only in SCROV-50
Deluxe Snap Snap Rover) contains a complex
electronic circuit to control when the loading and
launching motors start up and shut down, and to
flash the lights in the “eyes”. Its schematic is
