The RCX is a programmable microcomputer that is used as the "brain" in robotics systems. It can control motors and take measurements with different sensors while a program made in a PC is executed.

Characteristics:

• Contains 3 analog/digital inputs suitable for sensors, and 3 variable outputs.
• 9V powered, with 6 AA 1,5V batteries, or using a transformer (Ref. 9833) not included.
• Able to storage up to 5 different programs of up to 1500 instructions.
• Microcomputer: HITACHI 16K ROM, 512 Bytes SRAM + 32 K SRAM.
• It also includes an small speaker capable to reproduce tones, and a cronometer,
• It is possible to communicate one RCX with another RCX.
