Category: Development Board, AVR Microcontroller, ATmega2561, ATmega
Keywords: Microcontroller, Development Board, Prototype Board, ATmega Board, AVR ATmega2561-16AU, ATmega2561-16AI, ATmega2561 Board

ATmega2561 Development Board / Prototype Board with ATmega2561-16AI / ATmega2561-16AU (16 MHz) with ISP Header, ATmega2561 Board, ATmega Board

• full motherboard / prototype board for ATmeg2561
• same dimensions as Vers. 1.1 but with additional ISP header
• led indicates programming mode
• lines on right header are switched off automatically when in programming mode
  (prohibits "shortages" during programming with the rest of circuitry)
• 100% pin compatible with Vers. 1.1
• super thin only 34mm x 40mm x 8mm (mini module)
• all pins are available on headers (2,54mm-/0,1" pitch) 2x15pins each
• high computing power 
• easy to use: just connect to power supply (+5V) and program device
• 2 crystals: 16 MHz system clock, 32.768 kHz asynchron timer/counter0
• separate grounds: analog and digital
• large continues ground plane / reference plane for improved signal integrity and shielding
• low voltage option (2.7V-5.5V) with 8 MHz
  
  

• fully assembled board includes:

• ATmega2561-16AU (-40 bis +85°C), X1 crystal 16 MHz, X2 crystal 32.768 kHz (for asynchron timer)

• header layout, schematics, programming tutorial 

• female connectors 2 pieces (2x15 pins) are also available

options:

• ATmega2561-16AU with 14.7456 MHZ crystal for serial communication (USART1 and USART2) without baud rate error
