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 48.6 × 34.3 mm, has 2 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 Reon-02/PCB-Design-with-KiCad-Udemy 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 Reon-02. 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.
