2 Hardware (EVB) Details
This section describes various components and connection headers of RS9116 EVB. n-Link® (Hosted) solutions support
SDIO and USB interfaces only. The same EVB can also be used for WiSeConnect® (Embedded) solutions, where we
support UART, SPI, USB and USB-CDC interfaces.
Figure 1: RS9116 EVB
Option
Feature name
Description
1
Power USB
It is used to supply power to the EVB. While using USB
interface, connecting power USB is optional as power
drawn from USB itself.
2
USB
It is the port for USB interface used to communicate with
host.
3
SDIO/SPI
It is the common port for both SDIO and SPI interface,
used to communicate with host. Note: In nLink only SDIO
is supported.
4
Measurement
It is a provision to measure current consumption of chip
using ammeter or Digital Multi meter.
5
3.3V/1.8V Voltage
selection
It is a provision to select the operating voltage of chip. User
need to set this to either 3.3V or 1.8V selection.
6
Reset Switch
Provision to reset chip

Power save GPIO’s
These are GPIO’s which need to be connected
appropriately to the host, while using GPIO handshake
in ULP or WOWLAN. Please refer TRM for more
details.

Onboard antenna
/Internal Antenna
This is an onboard antenna used for wireless
communications
9
External Antenna
UFL connector
Provision given to connect external antenna as per the
requirement.

Power Supply and Interface Connectivity:
The board is designed to configure the module to use the interface on which power supply is detected. This is indicated
through the LEDs mounted on the board. The SDIO interface requires power supply to be provided over the USB
connector. Hence, for SDIO interface, it is required that the power USB be connected first (i.e power up first) followed by
the SDIO or SPI connection.
Follow the below steps to use the EVB with possible host interface options:
1. USB: Connect the Micro A/B-type USB cable between a USB port of a PC/Laptop and the micro-USB port
labeled USB on the EVB.
2. SDIO Mode: (For SDIO Header Pin Description, please refer to Appendix A. Appendix A: SDIO Header Pin Description.)
Current Measurement:
There is a 2-pin inline jumper available for measuring the current being sourced by the module during different stages of
operation. This is labeled as "MEASUREMENT" on the baseboard. The user may connect a power meter or an ammeter
to this jumper to measure the current.
Note:
Make sure the ISP switch is in OFF state. If it is ON state you will not get the boot loader messages

3 Software Details
Driver: https://www.silabs.com/wireless/wi-fi/rs9116-wi-fi-transceiver-modules
RS9116.NB0.NL.GENR.LNX
The driver software is delivered as a tarball with a filename in the format: RS9116.NXX.NL.GENR.LNX.x.y.z.zip
Where the naming convention is as follows:
NXX – defines whether the package supports only Wi-Fi (N00) or Bluetooth Classic/Low Energy along with Wi-Fi(NB0).
x.y.z – identifies the software release package version.
The software package contains the following files/folders:
• Readme.txt
• Releasenotes.txt
• Documents
• Binary_files (optional)
• source (optional)
Either of the Binary files or source folders might be empty depending on the request we have sent to Silicon Labs and
whether we have signed into a Software License Agreement for the source code.
If the source code has been provided, follow the instructions given below to compile.
3.1 Compilation Procedure
Go to source code path
# cd RS9116.NXX.NL.GENR.LNX.x.y.z/source/host
Following are the options available in menuconfig of the driver:
• USB Interface support
• SDIO Interface support
• Operating system: Linux or Android
• Nl80211 support
• HOSTAPD Support
• WIFI
• BLUETOOTH
• ZIGBEE (ZigBee is not supported in current release)
1. To open menuconfig utility, untar the release package, go to source → host folder and enter the given command
below
# make menuconfig
2. Below images explains usage of menuconfig utility. User has to select the required Protocol (Wi-Fi/BT) as per the
User's end application.
