Assemble the CUBEX Motherboard, MCU first, test by reading device ID using the ICSP port, then assemble the rest.
Assemble the CUBEX Camera, Radio, and Solar Cell board.
Powering the Motherboard, Camera, and Radio board using a power supply set to 3.3v, upload the code available at: https://github.com/arkorobotics/CUBEX_V1/tree/master/Code
Plug in a USB-RTL (or any sdr device) to your computer, tune (using the sdr-sharp) to 434.460Mhz USB and wait for SSDV/RTTY signal.
Decode the SSDV/RTTY data using the DL-FLDIGI HAB Mode software: http://ukhas.org.uk/projects:dl-fldigi
Finally, assemble CUBEX Power Board, LTC3536 section first, connect a power supply (set to 4.2v) to the battery input and measure the LTC3536 (buck-boost) output to assure the output is 3.3v. Then solder on the LTC3105 (solar charger) and solar cells to the CUBEX Solar Cell board. Connect a lipo battery, to complete the build.
