PIN NO.
NAME
DESCRIPTION/TYPE
1
GND
GND
2
ANT
Diversity Antenna. Leave unconnected
3
RSTN
For standalone operation, shunt this pin to GND with
100nF. For an application running on an external
MCU, this pin should be connected to a Host MCU
IO and used to reset the DHAN-T
4
DCINS
Leave as not connected (NC)
5
GPIO17
6
SCL (GPIO0)
GPIO or I2C Clock. Open Drain, reset value is
floating. Leave as not connected if not used
7
SDA (GPIO1)
GPIO or I2C Data. Open Drain, reset value is
floating. Leave as not connected if not used
8
