The board is for FTDI's popular USB to UART IC. Now with internal oscillator and EEPROM, the FT232RL is an impressive IC.It is open source so driver is available for Windows,Linux and Mac OSX
The module is designed for accurate measurement of humidity and temperature. The sensor is equipped with Si7021 chip with I2C interface, which provides industrial accuracy of measurements.
The chip contains an analog-to-digital signal processing converter, calibration data and an I2C interface.
The AD8232 is an integrated front-end for signal conditioning of cardiac bioelectrical signals for heart rate monitoring.
This is a low-power, single-lead, heart rate monitor analog front end for a wide range of vital signs monitoring applications.
This a high sensitivity vibration sensor often used for security detector. This sensor is highly sensitive with extremely fast response time which could be used for security applications such as anti-theft system for vehicle. The sensor will output a low logic voltage when vibration is detected. The sensitivity can be adjusted with the onboard potentiometer.
