AVR Butterfly Carrier - Features
Atmel's AVR Butterfly
The AVR Butterfly is based on the ATmega169 MCU (with built-in LCD driver) and has a seven-digit, 16-segment LCD glass (eight digit, actually, but one isn't connected), a joystick, photocell, thermistor, piezo speaker and interfaces for external circuits. There are lots of things you can do with this very inexpensive device. It even has a pin so you can wear it on your shirt!
However, as it is so small and light, it can be a bit difficult to get to grips with. There is no space for expansion and you could easily end up burying it in a tangle of wires. Finally, the battery has almost no spare power for additional circuits.
The ECROS Technology AVR Butterfly Carrier
The ECROS Technology Butterfly Carrier makes working with the Atmel AVR Butterfly simple and convenient. By mounting your Butterfly on the ECROS Technology Butterfly Carrier, you can make use of the following convenience features:
- an external power source using almost any DC wall-wart
- an external power source using a battery
- a power indicator LED
- enough power for your own additional circuits
- a serial 6-pin in-system programming header located at the rear of the assembly
- a 10-pin JTAG in-circuit emulation (ICE) header located at the rear of the assembly
- a DB9 connector on the left for a serial interface cable
- a reset button on the right hand side
- more than six square inches of prototyping area at the front
- all interfaces brought to the edge of the prototyping area for easy access
- an oscilloscope or multi-meter ground pin
