About the Attendance-Reader PCB

Attendance-Reader is an open source AVR/Arduino PCB design by meerfahim, published on GitHub. It is a 2-layer board measuring 123.2 × 90.2 mm, with 8 components from 8 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. By type, the board carries 7 connectors and 1 module.

From the project

This project is created for a client who is developing an attendance reader. In this project, I have designed the schematic and the PCB for the system and delivered it to the client.

Attendance-Reader: common questions

What microcontroller does the Attendance-Reader use?

The Attendance-Reader is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Attendance-Reader PCB?

The Attendance-Reader measures 123.2 × 90.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Attendance-Reader?

8 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Attendance-Reader design files?

From the meerfahim/Attendance-Reader repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Attendance-Reader design in my own project?

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

Can I test firmware for the Attendance-Reader 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.
