The AVR Butterfly is an evaluation kit for the ATMEGA169 microcontroller that was custom designed with an AVR core and peripherals to make it both a general-purpose microcontroller and an LCD controller. This little board is by far the lowest cost system for learning and developing.
It is simply amazing what the Butterfly++ has built in:
- 100 segment LCD display
- 4 Mbit (that’s 512,000 bytes!) dataflash memory
- Real Time Clock 32.768 kHz oscillator
- 4-way joystick, with center push button
- Temperature sensor
- ADC voltage reading, 0-5V
- Piezo speaker for sound generation
- Header connector pads for access to peripherals
- RS-232 level converter for PC communications
- Bootloader for PC based programming without special hardware
- Pre-programmed demos with source code
- Built-in safety pin for hanging from you shirt (GEEK POWER!)
Other Components Included:
- CdS Light Meter
- DB-9 Female connector and wire for RS-232 serial communication
- Battery holder with switch for 2 AA size batteries
- LED and resistor for power-on indicator
- 2 2x5-pin female headers for I/O ports
- 2-pin female header for voltage reader
- 4-pin female header for USI port
AVR Butterfly can be reprogrammed from AVR Studio using just a serial cable. This allows the tool to be used as a development kit for the onboard ATmega169, or even as target hardware for simple applications. The bootloader source code is available as application note AVR109.
The Butterfly++ Mini Kit requires soldering devices to the Butterfly and thus this product is non-returnable.
