Building an ATmega 1284p based data logger

1284p MEGA based Cave Pearl in ‘Prototyping Trim’ with I2C OLED screen & ADS1115 ADC. INT1 & Aref jumpered

Detailed instructions of how to build an ATmega 1284p based data logger: [via]

In this tutorial, a logger is built using a 3.3v Moteino MEGA with a 1284p CPU @ 16Mhz, w 4K eeprom,16K SRAM for variables & 128K program space. Considerably more than the 328’s 1K eeprom, 2K ram & 32K progmem. Also has a spare serial port for GPS/NEMA sensors.
