BITalino Freestyle Kit
Hardware platform for biosignals acquisition and wireless transmission
The BITalino Freestyle Kit is an easy-to-use, versatile and scalable hardware platform for biosignals acquisition and wireless transmission in real-time. This manual will describe the main functionalities, and introduce the main steps necessary to start using your device.
The BITalino DIY biosignal kit is also suited to university- and research equipment.
This kit includes:
- 1x BITalino hardware (MCU, Bluetooth, Power, ECG, EMG, EDA, Accelerometer, Light, LED) with all individual blocks detached: we carefully snapped off the pieces for you
- 1x 3-lead accessory (for EMG / ECG)
- 1x 2-lead accessory (for EDA)
- 5x Pre-gelled electrodes
- 1x Li-Po Battery 320mAh
The BITalino Freestyle Kit is shipped with all the individual blocks (MCU, Bluetooth, Power, ECG, EMG, EDA, Accelerometer, Light, LED) detached for you, enabling you to design your own BITalino-based creation.
Out-of-the-box your BITalino has all the components you'll need to start working with physiological data. Over the following sections we will describe the different modules and sensors with connection tips and examples.
- Sampling Rate: Configurable to 1, 10, 100 or 1000Hz
- Analog Ports: 4 input (10-bit) + 2 input (6-bit)
- Digital Ports: 4 input (1-bit) + 4 output (1-bit)
- Data Link: Class II Bluetooth v2.0 (range up to 10m)
- Sensors: EMG; ECG; EDA; Accelerometer; Light
- Actuators: LED
- Weight: 30g
- Size: 100x60mm
The micro-controller unit (MCU) block converts the analogic signals from the sensors to a digital format, and samples all of the channels. The MCU provides access to the BITalino analog and digital channels, as well as to the peripherals. Figure 1 shows the pinout.
The power management block provides energy to all the other BITalino blocks. This module also has a built-in charger that controls the battery charging. Charging is made when the device is turned off by connecting a power supply to the Micro-USB port. This block also provides access to control signals, the pinout can be seen on Figure 2.
