RB-Plu-01

HeartBIT BioMedical Development Kit

• 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

Micro-Controller

• 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.

Power

• 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.

ECG

• Conduction of action potentials through the heart generates electrical currents that can be

picked up by electrodes placed on the skin. A recording of the electrical changes that

accompany the heartbeat is called an electrocardiogram (ECG). Variations in the size and

duration of the waves of an ECG are useful in diagnosing abnormal cardiac rhythms and

conduction patterns. The ECG works mostly by detecting and amplifying the tiny electrical

changes on the skin that are caused during the heart muscle cycle during each heart beat.

LED • The LED module consists in a simple Light-Emitting Diode (LED) that turns on when the input signal is high and turns off when the input signal is low. Applications • The main application of the LED is related to video synchronization. When associated with the signal threshold it also can be a good visual feedback indicator.
