Board Features – Rev B
(See version 1.0 of this document for a labeled Rev A diagram and features.)
1) Propeller Multicore Microcontroller System
• 64 Kilobyte I2C EEPROM for program and data storage
• 8 core Propeller P8X32A microcontroller
• 5 MHz crystal oscillator
The P8X32A microcontroller has 8 cores, so it can do many different things at the same time. It uses I/O
pins P28 and P29 to communicate with the I2C EEPROM for program and data storage. The crystal
oscillator connected to the Propeller provides a clock signal for the system. The Propeller can multiply its
5 MHz oscillator signal by up to 16 for a system clock frequency of 80 MHz.
2) Power Jack
The 2.1 mm center-positive power jack is one of two power input options. The board accepts 6 to 24
VDC from this connector, although a maximum of 15 VDC is recommended. This option is useful for
robots and other remote applications when the board is not powered from a computer’s USB port.
Parallax’s 7.5 V, 1 .6 A supply (#750-00009) and 12 V, 2 A supply (750-00003) work well with this board.
3) 1.8 A Voltage Regulators
The 5 and 3.3 V switching regulators can deliver up to 1.8 A each, with a 6 to 24 volt input, although a
maximum of 15 VDC is recommended. Sockets along the breadboard provide power, from both
regulators to circuits built on the breadboard. A jumper along each pair of servo ports optionally
connects the regulated 5 V supply to the servo port. The 3.3 V regulator powers the Propeller
microcontroller and accessories, including any modules connected to the wireless programming and
communications socket.
