5V USB Output Converter Module
This is a DC to DC Buck converter module which provides 5V USB output from 7 ~ 24V input power. It can be used as a charger for mobile phones, tablets, MP3 players etc and for powering other USB powered devices. You may also power this module from battery. Its conversion efficiency is very high as it uses switched mode buck conversion. Make sure that the polarity of input supply is correct before providing power otherwise it may burn this module.
CP2102 USB to UART Converter
The CP2102 USB to UART Converter Module provides a serial port for your computer, ie. a virtual COM port to connect to a serial device. The IC used CP2102 is stable and reliable. It supports baud rates from 300bps to 1.5Mbps and driver support for a wide range of Operating Systems.
DC to DC Adjustable Buck Converter
Save energy by using this DC to DC Adjustable Step Down (buck) converter made with IC LM2596S. Conventional voltage regulators like 7805, 7812, LM317 etc drops extra power as heat. So the conversion efficiency is very low, but this module has high efficiency as it uses Switched Mode Conversion.
