I2C Driver
I2C is the name for a two-wire serial bus protocol originally developed by Phillips. It commonly is used in embedded systems so different components can communicate; PC motherboards use I2C to talk to different sensor chips.
Motor Driver
The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously . This Motor Driver is designed and developed based on L293D IC. L293D is a 16 Pin Motor Driver IC. This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V.
Buck converter module
Buck converter module is used for voltage step-down so please make sure that input voltage is higher than output voltage. Input and output are designed with screw terminals for convenient connection. Widely used for low voltage system power supply, 6V, 12V, 14V, 24V battery charging and regulated power supply.
Boost converter module
A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load).
Relay Module
A power relay module is an electrical switch that is operated by an electromagnet. When the relay is de-energized, the sets of contacts that were closed, open and breaks the connection and vice versa if the contacts were open.
