The new hardware version utilizes the RK816 PMIC IC, adding IR control for learning commands and controlling devices.
It also incorporates a dedicated Si5351 for PWM signal generation and a Max98357 to enable Fenilni to produce audio like a phone, eliminating the buzzer with beep tones, making everything truly audio-oriented. 

The new casing version also allows for a doubling of the battery capacity, increasing it from 150mAh to 300mAh.
