BF1.5 is part of a modular system for creating embedded systems based on the Atmel AVR® microcontroller. It includes a module made of high-grade materials with extra features such as an integrated interface for connecting to the microcontroller, easy-to-use plug-in components and cables, a power supply connector, and an extension board. Its user-friendly pin-layout makes it easy to create custom applications with no need for complex wiring. Its functions include 24mA current output, SPI-bus, LCD support, I2C-bus, SRAM, EEPROM, UART, timers, analog converters and more. It also features an integrated debugger, making it quick and easy to debug and optimize code. On top of all that, it comes with a free software development kit for creating firmware for application.
