From the project

Solid-state PIN diode dosimeter for manned spacecraft. Liulin detector replacement.

SPACEDOS is a miniature and lightweight version of AIRDOS02 cosmic radiation dosimeter modified for use onboard manned spacecraft.

The device is currently being used onboard ISS. The following pictures show the processed data from the flight. Here is a radiation map, where the South Atlantic Anomaly is visible.

The following spectrum is a cumulative sum of all the measured particles during the flight.

SPACEDOS02: common questions

What microcontroller does the SPACEDOS02 use?

The SPACEDOS02 is built around the ATMEGA1284P-AU, from the AVR/Arduino family.

How big is the SPACEDOS02 PCB?

The SPACEDOS02 measures 38 × 200 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SPACEDOS02?

120 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the SPACEDOS02 design files?

From the UniversalScientificTechnologies/SPACEDOS02 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SPACEDOS02 design in my own project?

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

Can I test firmware for the SPACEDOS02 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.
