Arduino Proto Board

An Arduino compatible proto board was realized as part of a larger project. Provisions were made to include additional features for future use. The board is based on the Atmega128 and includes an AT86RF230 for 802.15.4 RF communication, a DS1307 RTC with a 1 farad supercap backup, an FTDI232 for USB to serial bridge, an SN75176 for RS485 communication, numerous port headers including an 8bit LCD connector and two  buck mode power supplies providing 5 volts and 12 volts at 2 amps based on the TPS5420. The intended  code written for the board consisted mainly of RF communication and motion control algorithms.
