To further improve the PiRadio I created a PCB which addresses all components used and makes the cabling easier.
The PCB handles the power circuit based on the PowerBoost 1000C with the possibility to power-on/shutdown the Raspberry Pi with a simple button press (see https://github.com/NeonHorizon/lipopi/blob/master/README.power_up_power_down.md#a-simple-press-no-hold-power-up-version) and voltage monitoring of the battery (see https://github.com/craic/pi_power#voltage-monitoring-with-an-adc). The battery state is available by two leds.
Additionally the DAC Pins, the WS2812B LEDs Pins and the Button Pins can be connected directly.
