The USB Converter Serial (FT232RL) Rev1 has as its objective to convert USB to Serial communication. You can use it for communication (including programming) Microcontrollers (eg ATmega328 present in Garagino Rev 1), or make the communication with devices such as sensors and xbee modules, Bluetooth, among others.
Hardly we found devices with Serial ports (Ex. PC's) available today. Then you must use a USB / Serial converter for communication between the peripheral and the PC or other equipment using USB port.
Serial communication is done by:
Garagino is an Arduino UNO Compatible board developed by GarageLab team for makers who want smaller and cheaper prototypes.
The B3 Compact charger is a very simple to use charger for 7.4 2S and 11.1 3S battery packs. No need for additional power supplies or 12v batteries as this little unit has its own built in power supply that can be powered with 100-240v.
