About the ATMEGA328P-AU Data-Logger PCB

ATMEGA328P-AU Data-Logger is an open source AVR/Arduino PCB design by pushtiujeniya, published on GitHub. It is a 2-layer board measuring 53 × 36.2 mm, with 25 components from 15 distinct parts.

Its main chip is the ATMEGA328P-AU, from the AVR/Arduino family. Other key parts include the 24LC1025 and DS1337S_. By type, the board carries 7 resistors, 5 capacitors, 4 ICs, 4 connectors, 2 crystals and 2 diodes.

From the project

- ATmega328P-AU AVR Microcontroller - Dual 24LC1025 External EEPROMs - DS1337S RTC (Real Time Clock) - I2C Communication Bus - UART Header - SPI Programming Header - External Crystal Oscillator - Battery Powered Design - Compact 2-Layer PCB - GPIO Breakout Header - RTC Backup Sup

- ATmega328P-AU AVR Microcontroller - Dual 24LC1025 External EEPROMs - DS1337S RTC (Real Time Clock) - I2C Communication Bus - UART Header - SPI Programming Header - External Crystal Oscillator - Battery Powered Design - Compact 2-Layer PCB - GPIO Breakout Header - RTC Backup Support

This allows both EEPROMs to operate on the same I2C bus with different addresses.
