Satpack schematic progress

Here's a picture of the in-progress Eagle schematic view for Satpack, my altoids-sized, atmega-driven satellite tracking dongle for the FT-817 (or TH-D7A, or whatever). The 20-pin SOIC chip is meant to be a DS3231 or DS3235 Realtime clock. If someone writes a library to access the FRAM on the DS3235, I'll forego a EEPROM chip; likely I'll put one on the I2C bus just to be sure.
