About the MCU-data logger PCB

MCU-data logger is an open source AVR/Arduino PCB design by chislonljoseph, published on GitHub. It is a 4-layer board measuring 53.1 × 35.5 mm, with 25 components from 16 distinct parts.

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

From the project

MCU Data Logger PCB Design using KiCad

A custom PCB designed in KiCad for an ATmega328P-based MCU Data Logger. This project demonstrates the complete PCB design workflow, from schematic capture and PCB layout to 4-layer stackup conversion and Gerber generation for fabrication.

- Complete schematic design - Footprint assignment - 2-layer PCB layout - Conversion to 4-layer PCB stackup - Design Rule Check (DRC) - Copper pour - Gerber generation - Git version control

MCU-data logger: common questions

What microcontroller does the MCU-data logger use?

The MCU-data logger is built around the ATMEGA328P-AN, from the AVR/Arduino family.

How big is the MCU-data logger PCB?

The MCU-data logger measures 53.1 × 35.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MCU-data logger?

25 components, from 16 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MCU-data logger design files?

From the chislonljoseph/MCU-data-logger repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

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

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

Can I test firmware for the MCU-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.
