About the Silver PCB

Silver is an open source Microchip SAM PCB design by Foalyy, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 69 × 31 mm, with 95 components from 36 distinct parts.

Its main chip is the ATSAM4LSxB, from the Microchip SAM family. Other key parts include the TLV70233_SOT23-5, MCP73831-2-OT, LoRa_RFM9x, TPS2112A and TPS22917. By type, the board carries 28 resistors, 27 capacitors, 9 transistors, 8 connectors, 8 switches and 7 diodes.

From the project

Kicad project for the Silver open-source, long-range camera remote control

Silver is an open-source project aiming at making a long-range and fully-featured camera remote control.

See https://silica.io/tag/silver/ for a more detailed build log of the project.

This is the repository of the Kicad project with the schematic and layout of the board. See the main repository at https://github.com/Foalyy/silver-firmware.

Silver design files

The KiCad project lives in the Foalyy/silver-kicad repository on GitHub; these links point at the commit this page was built from.

Silver: common questions

What microcontroller does the Silver use?

The Silver is built around the ATSAM4LSxB, from the Microchip SAM family.

How big is the Silver PCB?

The Silver measures 69 × 31 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Silver?

95 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Silver design files?

From the Foalyy/silver-kicad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Silver design in my own project?

Yes, under the terms of its GPL-3.0 license, which Foalyy chose for the repository.

Can I test firmware for the Silver 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.
