MIKROE-977 mikroElektronika, MIKROE-977 Datasheet - Page 8

• Manufacturer Part Number: MIKROE-977
• Description: Development Boards & Kits - AVR READY FOR AVR BOARD
• Manufacturer: mikroElektronika

Specifications of MIKROE-977

• Rohs: yes
• Product: Development Boards
• Tool Is For Evaluation Of: ATmega16
• Core: AVR
• Interface Type: UART, USB
• Operating Supply Voltage: 9 V to 32 V

Ready for AVR board can be powered in two ways: over USB
connection, or using external power sources, such as adapters,
or laboratory power supplys. USB connection can provide up to
500mA of current, which is more than enough for evey on-board
module and for operation of the microcontroller. If you decide
to use external power supply, you can choose bewteen AC/DC
adapter connector or power screw terminals . Voltage and current
values must be within
will indicate the presence of current. Use only one method for
powering the board.
