Propeller Robot Control Board (#28230)
The Propeller Robot Control Board from Parallax Inc. provides an excellent development platform for mid-
size robotics projects and experiments. The Propeller P8X32A-Q44 is the brains of the board, providing a
multiprocessor control system capable of performing multiple tasks at the same time. The Propeller Robot
Control Board also provides a 3.3V/5 V dual switching power supply, dual full bridge driver and 24 discrete
I/O pins on servo headers buffered by 5 V translators. 64 KB of EEPROM means there is extra non-volatile
storage for user data and a USB interface provides a convenient connection to a PC for programming or
communication.
