The upgrade of the third generation relative to the second generation is as follows
1. New LPF filter combination with smaller harmonics.
2. Better gain consistency, no need to frequently adjust radio power.
3. Almost perfect thermal runaway management ensures stable operation even when the working temperature reaches 70 degrees Celsius.
4. Based on more comprehensive thermal runaway management, intermodulation distortion is now reduced and linearity is further improved.
5. Independent OLED display screen power supply, further reducing the interference of OLED screen charge pump on ADC.
6. Some minor optimizations, such as power fuses, fan control, temperature sensing, etc
