The DIO_1 and DIO_2 IO can be outputs, or inputs. As inputs the digital threshold is 1.2V. To guarantee low it must be < 0.5V, or for high > 2.0V.

- ↑ This ground should be used for the power supply since it includes a ferrite bead to help suppress noise.
The DIO_1 and DIO_2 IO can be outputs, or inputs. As inputs the digital threshold is 1.2V. To guarantee low it must be < 0.5V, or for high > 2.0V. When the IO is low the external device needs to sink up to 3.5mA. When the IO is high the external device needs to source 10 uA max. There is an internal 1.5k pullup to 5V that will bias the input high. As outputs these IO can sink up to 500mA.
