 The NeoPixel protocol engine needs all interrupts on the Pico. This is the reason that it is not possible to combine servos and neopixel simultaneous on the same Pico.\\

+The ADC GP28 needs a 100k pull down resistor which is not on the PCB.\\
 The easiest way is to mount the resistor directly on the Pico board on pin 34 and 38:\\
 {{:wio:wiopico-01-patch.jpg?400}}\\
 In this way the ADC is also stable if the Pico is not mounted on the PCB; The configuration remains 0 as default.\\
