 Operating conditions

 Block Diagram

The following shows a simplified block diagram of the Application Board 3.0.

Module descriptions

Main switch
The switch controls the connection between the power source (battery or USB) and the power regulation domains.

 Programmable push buttons
Two programmable push buttons are connected to Ground individually through a 360ohm resistor. It is expected that the internal pull-ups of the microcontroller pins connected to the buttons are enabled to use the button with a falling- edge active-low configuration. The buttons are named BTN-T1 and BTN-T2.

 Debugger connector
This connector helps with recovery of a board with a corrupted nRF52840 while loading custom applications or similar. Debugging is possible with the connection of a Serial-Wire-Debug interface connector. An ARM Cortex-M4 compatible debugger can be connected using the standard ARM Cortex 10-pin, 2 row, 1.27mm pitch connector.

 Shuttle Board 3.0 connector
The Shuttle Board 3.0 connector allows for the connection of a Shuttle Board 3.0 to be able to prototype one or more sensors (depending on the Shuttle Board 3.0). Details of the Shuttle Board 3.0 connector can be found under 5.

 Temperature sensor
A digital temperature sensor, the Texas Instruments TMP112 is used to be able to measure the temperature of the board. The sensor can be accessed with the I2C-TEMP bus. Details on how to operate the sensor can be found in the datasheet.

Microcontroller
The Application Board 3.0 uses the uBlox NINA-B302 Bluetooth low energy module based on the nRF52840 chipset from Nordic Semiconductor. The nRF52840 among other features supports USB2.0 and Bluetooth Low Energy 5.0 Details about the module and the chipset can be found in the NINA-B302 datasheet and nRF52840 product specification respectively.

 External flash
A Winbond W25M02GW 2Gbit NAND Flash is connected to the Microcontroller using SPI. The external flash is used primarily for storing files, particularly sensor data log files. The files can be accessed from a host by switching the device to the pre-loaded MTP firmware mode and connecting via USB.

Status LEDs
The microcontroller controls the RGB LED. Details on the LED is controlled is found in Table 2 Application Board 3.0 pin description under the LED-CTRL bus.

 Power Good and Charging LEDs
The microcontroller does not control these LEDs, however they indicate the status of the board. The Power Good or PGOOD for short indicates that the board is powered over USB. The Charge LED indicates the charge status connected Li-ion battery. If a battery is not present or if the charging is complete, the LED is turned off.

 Li-Ion battery connector
The Li-ion battery connector allows for the connection of a Lithium Ion or Lithium Polymer battery. Do not connect any other type of batteries as this could damage the circuitry of the board and lead to an unexpected behavior, and possibly heating or a fire.

Getting started

Setup overview

It is recommended to use an ESD safe environment to operate the Application Board 3.0 as depicted in the image.

Connecting a Shuttle Board 3.0 board

Make sure that the pins are aligned correctly to avoid damaging the connector or bending the pins.

Once aligned, press down on the board with both thumbs to fit the Shuttle Board 3.0 onto the Application Board 3.0.

Connecting to the Application Board 3.0 using USB

Before connecting the USB cable, ensure that board is switched off.

Powering on the Application Board 3.0

To power on the board slide the main switch into the ON position.

Removing the Shuttle Board 3.0

Tug the Shuttle Board 3.0 back and forth to remove the Application Board 3.0. Avoid twisting and turning as this may dislodge the connector from the Application Board 3.0.
