It belongs with the sensors designs in this gallery.

From the project

Two-layer ATmega328P data-logger PCB with external EEPROM, DS1337 RTC, and I2C/SPI/UART expansion interfaces, designed in KiCad.

A custom two-layer embedded data-logger PCB designed in KiCad around the ATmega328P microcontroller.

The board integrates external non-volatile memory, a real-time clock, user/status interfaces, and communication headers to provide a flexible hardware platform for data acquisition and logging applications.

The board was designed to combine the core hardware required for an embedded data-logging system on a single PCB.

Data-Logger: common questions

What microcontroller does the Data-Logger use?

The Data-Logger is built around the ATmega328-P, from the AVR/Arduino family.

How big is the Data-Logger PCB?

The Data-Logger measures 64 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Data-Logger?

28 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Data-Logger design files?

From the Eid2512/Data-Logger-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Data-Logger design in my own project?

The repository has no license, so all rights stay with Eid2512. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Data-Logger without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
