About the Shield-A

Shield-A is an open source AVR/Arduino PCB design by rsedak, published on GitHub under the Custom license license. It is a 2-layer board measuring 68.8 × 53.6 mm, with 42 components from 16 distinct parts.

Its main chip is the Arduino_UNO_R3, from the AVR/Arduino family. By type, the board carries 18 resistors, 12 diodes, 4 switches, 2 transistors, 1 module and 1 connector.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Shield-A is Arduino Uno based shield for student education compatible with BASCOM-AVR(C) and Arduino IDE.

Shield-A is Arduino Uno based shield for student education compatible with BASCOM-AVR(C) and Arduino IDE. During programming please keep in mind next design rules: - D0-D7 — LEDs can be used only if D12 is set to OUTPUT HIGH state - LCD 1602 — can be used only if A3 is set to OUTPUT HIGH state - RGB LED — are connected in matrix (D5-D7 - colors; D8-D11 - LEDs) - D12 — enables D0-D7 LEDs - D13 — reserved for buzzer - A0 — reserved for potentiometer - A1,A2 — reserved for switch in INPUT_PULLUP mode - A3 — enables LCD 1602 back-light - A4,A5 — reserved for I2C communication with on board…

Shield-A: common questions

What microcontroller does the Shield-A use?

The Shield-A is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How big is the Shield-A?

The Shield-A measures 68.8 × 53.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Shield-A?

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

Where can I download the Shield-A design files?

From the rsedak/Shield-A repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Shield-A design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Shield-A 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.
