Description of the Board
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.
a. J4 at VM_3.3V for USB power
b. J4 at VBAT and battery connect to J10 for Battery power
4. On board sensors are available to develop sensor to cloud applications.
5. Switch:
a. Set U3 switch to V33_ARD for Shield mode
b. Set U3 switch to V_3.3V for Standalone mode

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 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.

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

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.

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.

Functional 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.
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 TWO
A
JTAG
B
RESET
C
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.

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 pinof 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.
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.
Mount the Talaria TWO EVB on the STM32 board on Arduino connector. Connect GPIO4 of Talaria TWO (J1
Connector) to Pin2 of CN6 connector. Talaria TWO uses this GPIO4 pin tointerrupt ST when Talaria TWO wants
to send data/notification to ST.

Power Measurement
The power consumption of the INP101x module is measured by either connecting a DMM on the jumper J4 or
supplying power directly on J4 using specialty power supplies like Otti Arc from Qiotech. Figure 9 shows the
connection setup to measure current consumption using Otti Arc.

Using Battery as Power Source
Header J4 will switch between VBat and Vm_3.3V. Figure 10 shows VBat connection.
Figure 10: J10 Battery connection
Note: When using a battery as a power source there will be an additional current draw from LED (D7 or D12
depending on board version). If attempting to measure an accurate module current draw from the battery
connection, the LED series resistor must be removed to disconnect the LED.
