74HC153 ( Dual 4-input Multiplexer) Expander Breakout This USB-to-UART bridge controller provides

This USB-to-UART bridge controller provides a simple solution to update the design of the RS-232 using minimal components and PCB space

especially given the fact that it combines both an accelerometer and a gyro

Uses readily available standard inductors

This means that it just requires one data line (and GND) to communicate with the Arduino

Contactless Infrared Temperature Sensor (MLX90614) is an Infra Red thermometer for non contact temperature measurements

74HC153 ( Dual 4-input Multiplexer) Expander Breakout This USB-to-UART bridge controller providesIntroduction : 74HC153 is a dual 4 input multiplexer. The device features independent enableinputs (nE) and common data select inputs (S0 and S1). For each multiplexer, the select inputsselect one of the four binary inputs and routes it to the multiplexer output (nY). A HIGH on E forcesthe corresponding multiplexer outputs LOW. Inputs include clamp diodes. This enables the use ofcurrent limiting resistors to interface inputs to voltages in excess of
