Electronic enthusiasts provide you with the circuit diagram of the wireless mouse design, I hope it can help you!
The device uses the codec circuit MC1450226 / MC145027 and the RF transmit / receive module TDA1808 / TDA1809 to cooperate with each other, and can flexibly manipulate the mouse within the range of 10 to 120m, and it does not need to make any changes to the appearance and internal circuit of the original mouse during production. It conforms to the operation habit, is convenient and reliable, and is very suitable for enthusiasts to make their own.
Under normal circumstances, there are 4 circuit cables inside the cable between the mouse and the computer (the circuit device can accept up to 4 data lines, and the reader can choose according to the actual situation of his mouse), which are the power supply positive pole, power ground, and data line. 1. Data cable 2. We cut the mouse connection to find these four lines, and use the data transmission terminals D6 and D7 of the MC14650 encoding circuit to receive the data from the mouse data line 1 and data line 2 and encode them inside the chip and pass the RF transmission module. TDA 1808 was launched.
After the RF transmitter module TDA1809 works, it will input the received coded information into the MC1450727 decoding circuit. After its conversion, the signals of the original mouse data line 1 and data line 2 will be restored at the chip data output terminals D6 and D7. The computer cable is sent to the computer.
It can be seen that the above circuit does not need to modify the mouse and computer, and does not need to install additional mouse driver software. All functions of the original mouse can also be used normally.
This circuit (see Figure 1 and Figure 2) can work without debugging as long as the selected components are normal.
Same as the led par20,PAR16 7w DIM led spot light (sometimes used as an interface, called MR16 or GU5.3) is a kind from a number of manufacturers to develop standard halogen reflector lamps. Today Par16 7W Dim Led Spot Light type LED lamp can also be seen.
PAR16 7w DIM led Spot Light are often used in place of standard compact fluorescent or incandescent bulb applications, including residential lighting and retail lighting.
PAR16 7w DIM led spot light was originally designed for slide projectors.
They are suitable for a variety of applications, require a low to moderate-intensity directional lighting, such as track lighting, recessed ceiling lights, table lamps, chandeliers, lamps, landscape lighting, retail display lighting and bicycle headlights.
Folding properties
PAR16 7w DIM led spot light is a name number, where "MR" represent multiple reflector (Multifaceted Reflector). 16 is the length of the diameter of the representative of the former, the number of unit length of multiples, the provisions of 8 units of 1 inch. In MR16 example, the first diameter is 16 units long, 2 inches in diameter before that 2x2.54cm = 5.08cm, diameter of about 5 cm long.
Glass lamp cup, high long life, reliable, halogen bulb brightness, cheap.
PAR16 7w DIM led spot light fatal flaw is: large power consumption, heat lamp great.
There cartridge Friends (flashlight enthusiast) because of cheap, high brightness, good floodlight, which was converted into a flashlight, good results.
Currently such a well-known manufacturer of light cup of GE common NVC, Philips, Osram.
Mingxue Optoelectronics Co.,Ltd. has apply the I S O 9 0 0 1: 2 0 0 8 international quality management system certificate, For PAR16 7w DIM led spot light we apply the CE, RoHS and SAA certificate for our led lighting product.
