Proof of concept
- Diversity bench test: https://www.youtube.com/watch?v=jwpYg-zWEIs
- Band/channel change and auto-search test: https://www.youtube.com/watch?v=jH8NeLfK5f4
Calibration
- Power OFF VTX.
- Power ON Goggles and then press button on tVRX.
- LEDs will make 5 short (100ms) blinks indicating, that lowest video signal detection in progress.
- When LEDs will stay lit, then power ON VTX.
- After about 2 seconds LEDs will make 5 long (900ms) blinks indicating that highest video signal detection in progress.
- When LEDs turn OFF for 2 seconds, then Calibration is done.
- Now tVRX will exit from Calibration mode and go to normal state.
Compiling
Use latest Arduino IDE.
You need to add ATtiny Support to Arduino IDE (Google the Internet). :)
In Arduino IDE Clock should be left as default = 1MHz (internal).
In this project we don't use Arduino bootloader. So, you need to export compiled binary from IDE and flash it with external programmer like USBasp.
Programming pads on tVRX:
All fuses leave default.

Questions
How big is the TinyDiversityRX5808 panelized PCB?
It measures 97 × 92 mm and has 2 copper layers, 0.8 mm thick.
What parts does the TinyDiversityRX5808 panelized use?
640 parts, built around the ATTINY85-20SU, MAX4624EUT and B5819WS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TinyDiversityRX5808 panelized KiCad files?
From the nppc/TinyDiversityRX5808 repository on GitHub, at the commit this page was made from: the board is KiCad/TinyDiversityRX5808_panelized.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyDiversityRX5808 panelized design in my own project?
Its repository states no licence, so its author keeps all rights: ask nppc before reusing the design.
