Category: Development Board, AVR Microcontroller, ATmega128, ATmega
Keywords: Microcontroller, Development Board, Prototype Board, ATmega Board, AVR ATmega128-16AU, ATmega128-16AI, ATmega128 Board

ATmega128 Development Board / Prototype Board with ATmega128-16AI / ATmega128-16AU (16 MHz) with ISP Header, ATmega128 Board, ATmega Board

• full motherboard / prototype board for ATmega128
• 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
• board fits in 2.54mm pitch prototype PCB
  
  

fully assembled board  includes:

• ATmega128-16AI /  ATmega128-16AU (-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:

• ATmega128L option - low voltage version (2.7V-5.5V) with ATmega128L-8AI / ATmega128L-8AU and 8 MHz crystal
  

• AT90CAN128 option - AT90CAN128-16AI / AT90CAN128-16AU with CAN Controller - V2.0A and V2.0B 
  (CAN 2.0A, CAN 2.0B)
  

• ATmega128-16 with 14.7456 MHZ crystal for serial communication (USART1 and USART2) without baud rate error
