About the Same70 PCB

Same70 is an open source Microchip SAM PCB design by brengi, published on GitHub. It is a 2-layer board measuring 62.5 × 87.5 mm, with 67 components from 31 distinct parts.

Its main chip is the ATSAME70N21A-AN, from the Microchip SAM family. Other key parts include the SN65HVD230, LM317_3PinPackage and 24LC1025. By type, the board carries 30 capacitors, 11 resistors, 8 connectors, 8 inductors, 5 diodes and 4 ICs.

From the project

Curso de Diseño de Circuitos Impresos de la Carrera de Especialización en Sistemas Embebidos

El Curso de Diseño de Circuitos Impresos (DCI) es una asignatura optativa de la Carrera de Especialización en Sistemas Embebidos (CESE) de la Facultad de Ingeniería de la Universidad de Buenos Aires (FIUBA). Tiene una duración de dos meses, organizados en 8 clases semanales de 3 hs cada una. Para aprobar la asignatura los participantes deben realizar el diseño de un circuito impreso a elección durante el curso. En esta página quedan registradas dichas prácticas.

Same70: common questions

What microcontroller does the Same70 use?

The Same70 is built around the ATSAME70N21A-AN, from the Microchip SAM family.

How big is the Same70 PCB?

The Same70 measures 62.5 × 87.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Same70?

67 components, from 31 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 Same70 design files?

From the brengi/CESE-PCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Same70 design in my own project?

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

Can I test firmware for the Same70 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
