About the Radio Software PCB

Radio Software is an open source Microchip SAM PCB design by silver-sat, published on GitHub. It is a board, with 57 components from 39 distinct parts.

Its main chip is the ATSAMD21J_QFN, from the Microchip SAM family. Other key parts include the 741G125DBV, NCP1117ST50T3G, LP2985-XXDBVR and SPI Flash. By type, the board carries 14 capacitors, 7 resistors, 5 ICs, 4 crystals, 4 LEDs and 3 inductors.

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

From the project

This is a copy of the Adafruit Metro M0 schematic with the "Custom AX5043 Hat" connections shown. This is an aid to help understand the variant file, and to show how it is connected.

Note that the interrupt pin from the AX5043 hat now has to be connected to D12.

Radio Software: common questions

What microcontroller does the Radio Software use?

The Radio Software is built around the ATSAMD21J_QFN, from the Microchip SAM family.

How many components are on the Radio Software?

57 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Radio Software design files?

From the silver-sat/Radio_Software repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Radio Software design in my own project?

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

Can I test firmware for the Radio Software 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.
