Three different boards for Arduino project
Because of delivery it was more cost effective for me to get DHL and get all delivered as a single package. The three boards are used in my "robo-clock" project but will also be very useful for many Arduino projects in the future. One allows easy and convenient connections to a 12 bit DAC and audio amplifier via SPI interface. The second board is a general purpose "bus board" that allows me to make multiple SPI and/or I2C connections to a single project. It also has a RTC1307 and SD card breakout connection built in. The third board is a breakout for 2 MCP23S17 I/O expanders organized nicely for RGB leds but not restricted to any single type of use.
