USB Kit with external power is primary to be used in devices with current bigger than 500mA, so for devices which can't be powered directly from USB port. This module can be powered with external power supply 8-15V, and you can power up your solution from this module.

 

 

 

Technical specification:

  • Processor:
    • Atmel AT Mega32U2 (32kbytes flash, 1024bytes eeprom, 1024bytes sram)
    • Atmel AT Mega16U2 (16kbytes flash, 512bytes eeprom, 512bytes sram)
    • Atmel AT Mega8U2 (8kbytes flash, 512bytes eeprom, 512bytes sram)
  • Crystal: 16Mhz
  • Inputs/Outputs: 21 user defined IO pins
  • Power:target application, or external pheripherals can be powered up directly from this development board:
    • If current is lower than 500 mA directly from USB port
    • If current is higher than 500 mA you can use additional external power supply 8-15V
  • Programming and debugging options:
    • ISP connector - possibility of programming and debuging using external programmer
    • On Chip Debug Interface (debugWIRE)
    • Atmel Flip compatible bootloader - external programmer is not needed
  • USB 2.0 Full-speed Device Module with Interrupt on Transfer Completion:
    • Data transfer rates at 12 Mbit/s
    • Fully independant 176 bytes USB DPRAM
    • 4 Programmable Endpoints
    • Microcontroller reset on USB Bus Reset without detach
  • Ostatné periférie:
    • One 8-bit Timer/Counters with Separate Prescaler and Compare Mode (two 8-bit PWM channels)
    • One 16-bit Timer/Counter with Separate Prescaler, Compare and Capture Mode (three 8-bit PWM channels)
    • USART with SPI master only mode and hardware flow control (RTS/CTS)
    • Master/Slave SPI Serial Interface
    • Programmable Watchdog Timer with Separate On-chip Oscillator
    • On-chip Analog Comparator
