There are several hardware versions and software branches to go with them - see below for information.
See the Wiki Software Install page for more details: https://github.com/alanbjohnston/CubeSatSim/wiki/2.-Software-Install. The software runs on any Raspberry Pi including the Raspberry Pi 4B, 3B, 3B+, Pi Zero or Pi Zero W.
See the Wiki Software Install page for more details: https://github.com/alanbjohnston/CubeSatSim/wiki/2.-Software-Install. The software runs on any Raspberry Pi including the Raspberry Pi 4B, 3B, 3B+, Pi Zero, Pi Zero W, or Pi Zero 2 W.
There are two ways to get the CubeSatSim software for your Pi.
One option is to download the disk image file and write it to a 16GB micro SD card or larger. The image is based on Raspberry Pi OS (Rasbian) Lite, dated December 2020. All software is installed, you just need to login to change your password and set your amateur radio callsign if you have one. You can run the ./update.sh script to update all packages and update and compile the latest CubeSatSim software.
The other option is to start with any Raspberry Pi OS (Rasbian) image and run the installation script ./install.sh which will install and compile all the related software. This includes the following packages:
The other option is to start with a Raspberry Pi OS (Rasbian) image (Bullseye or Buster works) and run the installation script ./install.sh which will install and compile all the related software. This includes the following packages:

## Installation Script Option Steps
CubeSatSim runs on any version of Raspberry Pi OS (Desktop or Lite), although a Pi Zero or Pi Zero W should only run Lite. Your Pi will need to have internet access to update settings and install packages.

The current CubeSatSim hardware is in the v1.1 folder. The folder contains gerbers, schematics, and images of the Main, Battery, and STEM Payload boards.
The current CubeSatSim hardware is in the v1.2 folder https://github.com/alanbjohnston/CubeSatSim/tree/master/hardware/v1.2. The folder contains gerbers, schematics, and images of the Main, Battery, and STEM Payload boards.
Note: the only differences between the v1.1 and v1.0 hardware is a Low Pass Filter instead of a Band Pass Filter - this only affects the SMD components.
Note: the main differences between the v1.2 and v1.1 hardware is a USB-C charging connector instead of the micro USB.
For information on building the boards, see https://cubesatsim.org/wiki.

NOTE: The change between v1.0 and v1.1 is changing the BPF to a LPF. Only the SMD components change - all the rest are identical
NOTE: The STEM Payload Board has a 1.1a version. The only change is a cutout on the edge of the PCB to increase clearance for the Pi Camera. Otherwsie, it is identical to the 1.1 version.

Here is information about the CubeSatSim v1.2 hardware
NOTE: The change between v1.1 and v1.2 is changing the USB charging connector from a micro USB to a USB-C connector. Some labels also changed
There are files for the main board, battery board, and STEM payload board of these types:
* cubesatsim-main-1.2_gerbers.zip -- All gerber files used to fabricate PCBs

This spreadsheet is for analyzing the CubeSatSim APRS and CW telemetry ONLY. Note that this spreadsheet is based on the original AMSAT OSCAR 7 AO-7 Morse Code Telemetry Decoder spreadsheet: https://www.amsat.org/amsat/ftp/software/spreadsheet/AO7tlmSS.xls
The best telemetry for the CubeSatSim is FSK which uses the AMSAT FoxTelem software to automatically demodulate, decode, and graph the data.
