NOW you’re looking at the almighty kahuna of the PICAXE lineup. With the most pins, most memory, and all the features of the X1 series, you’ll be hard-pressed to find a project that this chip can’t handle.

Features:

• 1000 lines memory
• 8-20 Inputs
• 9-17 outputs
• Hardware I2C support for easy peripheral connecting
• Internal Timer
• Increased variables and separate memory scratchpad
• Enhanced mathematical functions
• 3-7 8/10-bit Analog-to-Digital converters (ADC)
• 20MHz maximum operation speed (4MHz normally)
• Line-by-line simulation
• Supports
  • Interrupts
• • 12-Bit Digital temperature sensors
• • Servo control
  • Keyboard input
  • IR transmit/receive
  • Plays user-defined musical tones
  • PWM Motor control
  • Input Pulse counting
  • Serial output & debugging via programming cable
  • Higher baud rate for serial work
• Based on the PIC 16F887 IC

The PICAXE system is a powerful, low cost microcontroller programming system designed to simplify educational and hobbyist use of microcontrollers. PICAXE chips can be programmed in a graphical ‘flow-chart’ environment or in easy to understand BASIC.
