Laser Diode Module is a breadboard friendly, low cost having wavelength of 650nm and operating voltage of 5V. The laser head is composed of a light-emitting tube, condenser lens and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted glued by strong glue stick, which can work directly after connecting to a 5v dc power supply. Pay attention to the laser cell to prevent from being burnt or battery explosion due to a short circuit when removing the battery.
• The driver motor is based on L293D.
• Male burg-stick connectors for supply, ground and input connection.
• Screw terminal connectors for easy motor connection.
• L293D IC works on the basic principle of H-bridge
• By using L293D we can control two motors
• Voltage(VDC): 4.5 to 12
• Peak Current (A): 600 mA
• No. of Channels: 1
PL2303 – USB to TTL Serial UART Converter Module is a handy, low cost module. Adopt imported controller RS232 TTL, which can stabilize the flash with high-speed 500mA self-recovery fuse for protection.
Two data transmission indicator can monitor data transfer status in real time. Reserve 3.3V and 5V pin interface, easy for DDWRT of different voltage system that needs power. The entire board is coated by a high quality transparent heat-shrinkable sleeve, making the PCB in insulation state from outside, so that the board won’t be burnt down by a material shortcut.
