Overview of features

EsduinoXtreme comes equipped with a variety of interfaces and on-board resources. These include, but are not limited to, the following:

  • 8 MHz crystal, providing a 4 MHz nominal bus speed, when enabled.  This can be mutliplied by six, using the on-chip PLL, resulting in a 24 MHz bus speed
  • 1 MHz internal oscillator is the default clock source following powerup, before the oscillator is enabled.  This minimizes current draw and EMI.
  • Memory resources:  240K Flash, 4K EEPROM, 11K RAM
  • Operating voltage: 5V or 3.3V, jumper-selectable
  • Power sources: via USB port by default; can be powered externally via optional input jack through the on-board 5V regulator using an external 6-12 VDC power source
  • USB communication interface to host computer:  via FTDI chip, utilizing microB USB connector
  • User LED: red LED on DIG13 (Port J bit 0) available for application use
  • On-chip development support: adaptation of Freescale AN2548 Serial Monitor
  • BDM connector: 6-pin standard header enables the use of a separate BDM pod for for programming all Flash and EEPROM memories, and debugging programs in real-time
  • Input/output headers: emulate the Arduino Leonardo pinout, with four of the signals user-assignable via jumper blocks
  • Footrpint for optional user-installed SPI memory-device (EEPROM or Flash in SO-8 package)
  • Optional header footprint for adding wireless communications via the Digi XBee module, using the Technological Arts ADXB adapter
