MCU Data Logger: common questions

What microcontroller does the MCU Data Logger use?

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

How big is the MCU Data Logger PCB?

The MCU Data Logger measures 48.5 × 33 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. The full bill of materials is listed on this page.

Where can I download the MCU Data Logger design files?

From the AhmedAbo-Eita/Hardware_PCB_Designs 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 Data Logger design in my own project?

The repository has no license, so all rights stay with AhmedAbo-Eita. 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.
