Update 19-Jul-24: This was replaced by a Garmin GTX 345 transponder and Raspberry Pi 5 and other improvements.
My panel includes an accommodation for the SkyRadar DX to provide ADS-B 1090 MHz and 978 MHz UAT TIS. So the fancy box needed to live somewhere. It's also a backup AHRS so it needed to be oriented in a specific manner.
I decided to place it where the map box would be located. I just match drilled some aluminum angles. Here are two pics during the fitment process.
And the final install. The two wires with tiny Molex connectors are two unused serial inputs for the right GRT HXr EFIS.
Here is where I placed the 1090 MHz and the 978 MHz UAT antennas.
Update 7-Mar-24: Pic of the inside of the box. Turns out, it's not a Raspberry Pi in there, which is what I always assumed. I am impressed with the design.
ICs of interest:
- GPS receiver: Lantronix A2200
- Microcontroller: STM32F405
- USB controller: FTDI FT232RL
- FPGA: Cyclone IV (I presume this implements the SDR functions for demodulation)
- Flash memory: ST25P64
- SDRs: Maxim 2112E (1 each for 978 MHz and 1090 MHz)
- ADCs: AD9608 (1 each for 978 MHz and 1090 MHz)
Update 19-Jul-24: I upgraded my transponder to the GTX 345 then swapped out my SkyRadar for a Rasperry Pi running Stratux and Virtual Radar Server (git repository here) so I can see a lot more information about fellow aviators in the sky on my tablet or phone in flight, I removed the SkyRadar DX. I've now repurposed the SkyRadar as a local 978 MHz UAT feeder into my on site home Virtual Radar Server.
