About the MCU-Datalogger PCB

MCU-Datalogger is an open source AVR/Arduino PCB design by a-fratip, published on GitHub. It is a 4-layer board measuring 52.1 × 31.8 mm, with 25 components from 16 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

This is one of the PCB projects from the Kicad Like a Pro course. It contains a two and four layer board that implements a MCU datalogger with build-in 512K EEPROM and clock.

MCU-Datalogger: common questions

What microcontroller does the MCU-Datalogger use?

The MCU-Datalogger is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the MCU-Datalogger PCB?

The MCU-Datalogger measures 52.1 × 31.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MCU-Datalogger?

25 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the MCU-Datalogger design files?

From the a-fratip/MCU-Datalogger repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MCU-Datalogger design in my own project?

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

Can I test firmware for the MCU-Datalogger 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.
