Description: Aistin Blue boards are specifically designed for low energy, battery operated wireless IoT and wearable solutions. These small, round devices measure only 32 mm in diameter, or 27 mm, if screw pads and trace points are not needed, and are as thin as just 4.2 mm.
It is a very integrated and simple-to-use modular sensor system. The system has Bluetooth LE with an integrated crystal antenna, keeping it compact and avoiding external components. Blue boards work out-of-the-box with an Android application. Together with this application, Blue can be used immediately as data logger; sensor readings can also be seen instantly on the screen. Size matters, Blue is small enough for wearables, including wrist-worn devices.
Blue boards include sensors for detecting 3D-acceleration, 3D-magnetism, 3D-rotation, humidity, air pressure and temperature; even more functionality is available, using add-on boards and flexes from the Aistin family. More info about available variants will be available soon.
For product developers, sensor drivers are available at no charge. Application programming is easy with Nordic Semiconductor's tool set. Blue SW can be also developed with ARM MBED.
We at iProtoXi use Aistin Blue as a platform for customer projects, where we adapt it to perfectly fit the customer's specific needs.
Why Aistin Blue?
- Time to market advantages; reduced hardware development cost and time, direct Blue use, or customized hardware
- Well known ARM architecture and development tools
- Famous Nordic Semiconductor BT-LE system on chip solution
- Easy to extent solution with custom add-ons and flexes using Aistin Bus24, but keeping the solution still enough tiny to fit wearable size
- 2Mbit EEPROM Memory for customer application use and sensor data storage
- Low power consumption

Aistin Blue boards integrate low energy Bluetooth (BLE) with crystal antenna based on Nordic Semiconductor nRF51822 or nRF52832 SOC. See details from "Board Core" table below.
Most Blue variants have also 2 Mbit I2C EEPROM memory.
Aistin Blue boards are equipped with Aistin Bus24 host connectors based on the Aistin Bus24 open standard specification. Board has micro USB connector for data transfer (FTDI) and battery charging, power and charge control, smart switch, and programmable red, green and blue LEDs.
Blue Boards have build-in sensors for detecting motion, humidity, temperature and air pressure. Solution can be extended, but in same time kept still tiny by using Aistinbus24 add-on-boards or flexes. See variants from "Sensors in board" table below.
Aistin Blue supports firmware upload over-the-air via Bluetooth LE. Software development tools are provided by Nordic Semiconductor (downloadable for free). Software can be also developed with ARM MBED. Board supports also Tag-Connect connector less interface (TC2030) for flashing and debugging.
Dimensions: Ø 27/32 mm x 4.2 mm (0.6 mm PCB).

SW development tools
Blue application (firmware) programming is easy with Nordic Semiconductor's tool set. There are options to use Keil or Eclipse IDE. It is possible to develop Blue application (firmware) also with ARM MBED. When using ARM MBED, firmware needs to be flashed to Blue either using DFU (needs ZIP format) or by using debugger and TagConnect -cable.
Note: Aistin Blue Firmware source code example (Keil) is available on request for Blue customers. Please send mail to sourcesupport (at) iprotoxi.fi
DFU (over the air/BT) flashing
Aistin Blue supports DFU (Device firmware update over the air) -feature. With DFU you can download the latest firmware image to Blue without wires using Bluetooth. For DFU operation we recommend you to use nRF Toolbox application that is available from Android Play -store. See more info at https://www.nordicsemi.com/eng/Products/Nordic-mobile-Apps/nRF-Toolbox-App
- Prepare that you have BT-LE capable Android phone. Android version 5.x.x or later recommended
- Download nRF toolbox Ble Android application from Google Play.
- Install and open the application. Enable Bluetooth, if asked
- Select DFU operation from the application
- Download the latest Aistin Blue DFU firmware (like Aistin-blue-BTL3x3-V149.zip) from this page
- Select the Aistin Blue DFU firmware in nRF toolbox application
- Power on the Blue
- Select the Blue from nRF toolbox application
- Note: firmware can be updated only in Blue bootloader mode, so you need to keep the Blue power/reset button pressed, until you have started the DFU operation from the application
- Note: device BT name may be different during bootloader mode
- DFU operation should start, when pressing the "upload" from the application
Tag Connect interface (flashing and debugging)
Aistin Blue supports connector less Tag Connect interface for wired flashing. Tag Connect interface was selected because of zero cost solution in mass manufacturing. Developers can use Tag Connect interface for flashing and debugging either using J-Link debugger or using Nordic Semiconductor reference design kit.
When using Tag Connect interface, please use TC2030-IDC-NL cable (http://www.tag-connect.com/TC2030-IDC-NL).
When using J-Link debugger, you can either use Tag Connect ARM20-CTX 20-Pin to TC2030-IDC Adapter for Cortex http://www.tag-connect.com/ARM20-CTX or you can use iProtoXi adapter for TC2030-IDC (available on request).
When using Nordic Semiconductor reference design kit debug out, you can use adapter for TC2030-IDC provided by iProtoXi.

Interested of tailored version of Aistin Blue?
Are you looking perhaps something that is almost like Blue, but you would want to either drop, add or change some features?
We are happy to help you. We can tailor a custom version of the Blue boards for you needs. Customization scales form diffrent build variant to fully custom solution, where also the board layout and size can be designed to match your needs. We can also tailor the firmware and/or phone application for your use case. If you need custom mechanics and perhaps industrial design, we can help you to find the right solution.
If interested, please send us an email: info(at)iprotoxi.fi
Are you looking perhaps a complete wearable solution and you want to save time and money utilizing existing wearables/IoT platform instead of making own HW and firmware design from scratch? Please contact to info(at)iprotoxi.fi and we will explain the Blue license model benefits.
