A WIRELESS MOUSE WITHOUT POWER SUPPLY
The invention discloses a wireless mouse without power supply and its preparation method. There is a signal output terminal of a circuit board which is connected to a mouse circuit of a computer. Receiving and transmitting a signal from a card is done by the powerless IC card. receiving and transmitting induction coils and paralleled capacitors are present in the circuit and it can be on a contactless and powerless IC. the keys of the mouse are coupled in series to the connecting circuit of the contactless and powerless IC chip. The eceiving and transmitting induction coils also perform the task of recieving and transmitting the signals. The coding and decoding circuit encodes and decodes the signals. The advantage of the mouse is that operation signal of the mouse can be transmitted wirelessly and also the power is not needed. simple structure, light weight and convenience are the other features.
Ultra-Low-Power 27-MHz Wireless Mouse
Reference Design
The Texas Instruments (TI) MSP430 is a family of microcontrollers typically used in
many high-performance low-power human interface device (HID) applications, such as
a wireless mouse or keyboard. Here, a wireless mouse reference design is described. It uses a MSP430 microcontroller by the Texas instruments, ADNS-3040
optical mouse sensor and a TRF7950 27-MHz transmitter module.. Also available with trhis is the hardware schematics and the hardware schematics.
