Notes on the usage and functionality of the BITalino R-IoT

Postby BITalino » Wed Mar 15, 2017 8:30 am

Dear all,

These are exciting times at BITalino as our family gets bigger through the arrival of the BITalino R-IoT... a stamp-sized 9DoF high resolution IMU, which has branched into several useful accessories even for your existing kit (e.g. WiFi connectivity and an ARM MCU):

Developed in collaboration with world-renowned IRCAM ISSM, the BITalino R-IoT features a 9 DoF IMU with 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer, all having 16-bit resolution.

The BITalino R-IoT is powered by the Texas Instruments CC3200 module, which also means WiFi connectivity and a powerful 32-bit ARM Cortex MCU with seamless Arduino-like programming through the Energia IDE.

While the BITalino R-IoT Kit and BITalino R-IoT Barebone have all the features, it is important to highlight that to lower costs, the WiFi (W24) Block does not have the 9 DoF IMU and the Arduino-like Reprogrammable MCU (ARM) Block does not have the 9DoF IMU not the WiFi antena.

If your deciding about which R-IoT version is suitable for you and already have a BITalino (r)evolution kit, the most suitable option should be the BITalino R-IoT Barebone:

It can both be used standalone just as a 9DoF IMU or connected to the BITalino MCU via PCB headers:

While in standalone use, the R-IoT can be powered directly from a battery and on the MCU its powered from the system. Note that you’ll need to break away the existing Bluetooth or BLE module prior to connecting the R-IoT as an interface.

The good thing is that if you add PCB headers to the Bluetooth or BLE as well you can choose to choose to use either. Other important details are the fact the R-IoT starts streaming 9DoF + BITalino channels immediately when powered on.

In this setting the maximum sampling rate is 200Hz, although it should be suitable for most applications. Our R-IoT also carries an onboard web server for easy configuration of the network and IP address.

Attached you’ll find a few pictures... on the photo the R-IoT is connected on a board that didn’t have the Bluetooth module assembled; in your case you’d need to snap of that block and connect the headers on the MCU). Further details on the R-IoT are available here:

Hope you find this information useful. In case you have any further questions, just let us know.

Best regards,
The BITalino Team
