6Description of the board
6.1 Block Diagram
Figure 2: Block diagram of INP301x Evaluation Board
The block diagram of the INP301x Evaluation board is shown in Figure 2. The main component on
the board is the INP101x module. Key features of the evaluation board are:
1. Standalone mode vs. Shield mode: Using the mode switch U3, either standalone mode or
shield mode can be selected.
a. In standalone mode, the INP101x can be accessed via micro-USB cable for
programming and debugging. This mode is recommended for standalone
application development.
b. In shield mode, the INP101x module can be interfaced with any host CPU and can
provide serial to Wi-Fi capabilities.
2. A peripheral IO header (J1) is available using which all the IO’s of the INP101x module can
be accessed.
3. Power supply section: Based on the mode, the power for module is derived from either
USB or shield header. A battery header is available which can be used as power source as
well.

6.3 Power Supply and Mode Switch
The INP301x board is designed to supply power to the INP101x module in following ways:
1. In standalone mode, power is drawn from USB connector
2. In shield mode, power is drawn from shield connector
3. A battery header is also available to provide power to the module
Figure 4: Power supply section
The power supply section is shown in the Figure 4. The INP101x module requires 3.3V supply. The
DPDT switch (U3) selects between USB and Arduino header supply using the common net
Vm_3.3V. The jumper J4 is used to select between battery supply and Vm_3.3V. The same jumper
can be used for measuring current consumption of the module.

6.4 IO Header (J1)
The J1 header brings out all the IOs from INP101x module. These IOs can be used for debug, and/or
any external interfacing needs. The pinout of this header is shown in Figure 5. To work with on
board sensor, pins 1 & 2 needs to be shorted.

6.5 Shield Headers (JP1 to JP4)
Arduino UNO compatible headers are available in the INP301x board to interface with any
compatible host micro-controller.
The GPIOs assigned to shield headers are carefully chosen to achieve following capability:
1. INP101x’s SPI slave pins available on JP1
2. INP101x’s I2C master pins available on JP1
3. Remaining GPIOs are available on JP2 and JP4
Note that INP301x supports 2.5V IO as the default configuration. The shield header connections
are as shown in JP2 of Figure 6.

6.6 On Board Sensors
Figure 7: On board sensors
The INP301x board has following sensors available on board for quick prototyping/testing:
1. Temperature/Humidity (Sensirion SHTC3)
2. Pressure (Bosch BMP388)
3. Light (TI OPT3002)
To use the sensors, J7, J8, pins 1 & 2 of J1 should be connected. This enables power connection
to the sensors on board, I2C connection on GPIOs 3 & 4.

7Functional Description
Following are the functional modes that can be achieved in the INP301x board:
1. Stand-alone mode (host-less)
2. Shield mode (hosted)
More details about each mode are available in subsequent sections. Switching between the modes is
handled by DPDT switch U3 for power, and multi-port SPDT switch U1 for the GPIOs.
7.1 Stand-alone mode
The stand-alone mode is intended for following use cases:
1. Host-less application development on INP101x modules
2. Programing access to INP101x modules
In stand-alone mode, the U3 switch is pushed towards pin 3, which disconnects power and IO
from shield headers and connects them to FTDI. The FTDI port layout is shown in Table 2.
FTDI Bus
Interface to Talaria TWOTM

UART
D
CONSOLE (UART)
Table 2: FTDI Layout
The A & B bus of FTDI device supports MPSEE protocol, hence JTAG is assigned to A-bus. The
BDBUS7 is connected EN_CHIP of the INP101x module. The C & D bus of FTDI device used as
UARTs, with C-bus connected to peripheral UART of INP101x module and D-bus connected is
CONSOLE port (GPIO17) of INP101x module.
The JTAG on A-bus is used for debugging applications on the INP101x module. The UART on C-bus
is used for programming the INP101x module. The CONSOLE port is a unidirectional UART from
INP101x module that operates at high baud rate of 2457600, used for debug prints.

7.1.1 Driver Installation for Windows OS
On Windows OS, libusbK driver needs to be installed to communicate and control the
Talaria TWOTM module via the FTDI device on the evaluation board. The tools/applications
provided by InnoPhase will use this driver. Install/uninstall instructions for this driver is given
subsequent sections.
7.1.1.1 Installation instructions for libusbK driver
Download the free software Zadig, available here: - https://zadig.akeo.ie/. Connect
your Windows PC or Laptop to the evaluation board using the provided USB cable.
Now, open Zadig and click on Options. Select List All Devices and deselect
Ignore Hubs or Composite Parents as shown in Figure 8.

7.2 Shield Mode
This mode will make the EVB-A board to act as a Wi-Fi/BLE5 shield. To enable this mode, flip the
switch U3 towards V33_ARD. This also pulls up the INA pin of the multi-port SPDT device
MAX4761ETX, which then routes the GPIOs from the INP101x module to the shield headers JP1,
JP2, JP3 and JP4. In the shield mode a suitable firmware (such as Serial to Wi-Fi application
available in the SDK) should be pre-flashed in the INP101x.
7.2.1 EVB-A as Wi-Fi Shield with STM32 Nucleo Board
A comprehensive set of host application packages are available to download via the
InnoPhase website to demonstrate the use of EVB-A as a Wi-Fi/BLE5 shield board.
