About the RadioDev PCB

RadioDev is an open source AVR/Arduino PCB design by tmolteno, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 100 × 75 mm, with 99 components from 42 distinct parts.

Its main chip is the ATmega328PB-AU, from the AVR/Arduino family. Other key parts include the SP3485CN, conn2x18pcie, FT232RL, DS90LV028 and 78M05_Switcher. By type, the board carries 32 capacitors, 28 resistors, 14 diodes, 11 ICs, 6 connectors and 4 switches.

It belongs with the rf & radio and science & space designs in this gallery.

From the project

The TART radio telescope, Version 3.

TART-3/hardware contains the physical design files.

TART-3/hardware/lna is the design for the seperate low noise front end required when using passive antennas.

RadioDev: common questions

What microcontroller does the RadioDev use?

The RadioDev is built around the ATmega328PB-AU, from the AVR/Arduino family.

How big is the RadioDev PCB?

The RadioDev measures 100 × 75 mm, has 4 copper layers and is 1 mm thick.

How many components are on the RadioDev?

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

Where can I download the RadioDev design files?

From the tmolteno/TART-3 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the RadioDev design in my own project?

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

Can I test firmware for the RadioDev 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.
