Emphasis is on scanner functionality.
affordable arduino based 'openpilot' diversity board with 2 RX5808 modules (approx 15$ in 2021). Runs on either 5V or 2S-3S lipo (but onboard LDO gets really hot) use a large 2.43" ssd1309 128x64 OLED as dropin replacement for 0.96 ssd1306 128x64 OLED
- mostly identical to base etheli version
- Scanner is enhanced
- to work on frequency instead of bands/channels.
- uses most screen estate for graphing
- maximum range is from [5505 ; 5995] MHz
- scans and displays 120 steps
- up-button increases lower range boundary,
- down-button decreases upper range boundary
- Setup is likely broken atm
This "etheli" version of the open-source firmware for RX5808 Diversity modules (that plug into Fatshark Dominator goggles) is an enhancement to the RX5808 Diversity RealAcc Compatible firmware. The main improvement is the addition of a BY-MHZ MODE that allows an arbitrary frequency in MHz to be directly dialed in and tuned. Other enhancements and improvements are implemented; see the list below.
