This is a brand new design product, using the PL2303TA chip produced by Taiwan prolific company, PL2303TA provides an RS232-like full-duplex asynchronous serial device connected to any universal serial bus #40; USB#41; the host can be convenient solution. The PL2303TA is compatible with win XP/VISTA/7/8/8.1 systems and can emulate existing applications that allow COM-based ports on most operating systems to easily port and perform USB connectivity without rewriting COM port software applications. Traditional COM port.
By utilizing the USB bulk transfer mode, large data buffer and automatic flow control advantages, the PL2303TA can achieve higher throughput than the traditional UART does not require #40; Universal Asynchronous Receiver #41; RS232 signal, transmission rate Higher base points than 115200 can be used for even higher performance. The PL2303TA's flexible baud rate generator can be programmed to produce any rate between 75 base points and 6 million base points.
The PL2303TA is designed for mobile and embedded solutions and offers a compact and easily adaptable to any connector and handheld device. With the operating or suspend mode being very power hungry, the PL2303TA is powered by a left-handed device bus.
This product is specifically for laboratories, product testing, low-cost MCU communication and other applications.

The protective board can be used as the nominal voltage of 14.4V, 14.8V, 16.8V four series of polymer lithium battery group, four series of 18650 lithium batteries as overcharge and over discharge, short circuit protection. Without the activation function in the power application for high instantaneous current,and in inverter application for avoid false triggering protection.So it will use more convenient.
Note:No part design on the back, can be attached to the heat sink to ensure high current work situation for a long time. 
 

 
NOTE
As shown in the figure, the photosensitive probe is on the same plane, and the small solar panel seat shade is used above. When the light intensity of the left probe is greater than the right side, the motor turns left until the two probes balance the value. The size of the shade is related to the angular accuracy of the light source. It's best to cover both probes at the same time. The tracking angle accuracy is related to the probe placement position, angle, and shade size.

Warm reminder: it is a kit, not welded! ! !
