About the Radio module

Radio module is an open source AVR/Arduino PCB design by tmolteno, published on GitHub under the GPL-3.0 license. It is a 6-layer board measuring 69.7 × 37.4 mm, with 110 components from 38 distinct parts.

Its main chip is the ATmega328PB-MU, from the AVR/Arduino family. Other key parts include the MAX2769CETI+, LM1117-3.3, TLV70228_SOT23-5, SP3485 and DS90LV027A. By type, the board carries 51 capacitors, 27 resistors, 11 ICs, 8 diodes, 7 inductors and 4 connectors.

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.

Radio module: common questions

What microcontroller does the Radio module use?

The Radio module is built around the ATmega328PB-MU, from the AVR/Arduino family.

How big is the Radio module?

The Radio module measures 69.7 × 37.4 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Radio module?

110 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Radio module 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 Radio module 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 Radio module 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.
