The main control chip is usually required to have low power consumption characteristics so as to prolong the service life of the battery; meanwhile, the main control chip needs to support a bluetooth communication protocol, such as Bluetooth Low Energy (BLE), to ensure efficient data transmission. The first capacitor is used for power supply filtering and serves to smooth and filter the current from the power supply to ensure stable operation of the circuit and to help reduce noise and interference in the power supply. Power supply filtering is a very important ring in electronic devices, and particularly for devices requiring highly stable power supplies, the selection and layout of capacitors requires accurate design based on the power supply noise level. Inductors are commonly used to store electrical energy, i.e., the inductor can store current and discharge it when needed, helping to smooth out supply current in some cases, and provide power backup. The working principle of the inductor relates to the induction and storage of current, is usually realized by a coil mode, and can be used for equipment with high instantaneous power requirements, such as transmission peaks in Bluetooth communication.

The efficiency and range of bluetooth communications generally depends on the design and performance of the antenna, and antenna type and location selection have a tremendous impact on signal strength and coverage. The crystal oscillator is used for providing clock frequency, ensures the synchronism and the accuracy of data transmission and is a clock source of electronic equipment. The stability and accuracy of the clock frequency is critical to the reliability of bluetooth communications, and the accuracy of a crystal oscillator is typically measured in ppm (parts per million).

The SPI_MOSI line (Master Out Slave In) is used to transfer data from the host chip to the external device, while the SPI_MISO line (Master In Slave Out) is used to receive data returned from the external device. SPI is a common serial communication protocol, has high-speed data transmission and flexibility characteristics, is applicable to connecting external sensor, memory and other peripheral equipment, and SPI communication needs to ensure the accuracy of time sequence to avoid data collision and loss.

The use of SPI_CS lines enables the master chip to connect to multiple external devices simultaneously, each with a separate CS line. SWCLK and SWDIO lines are used for SWD (SerialWire Debug) debug interfaces, typically for debugging and programming embedded systems; the SWCLK line is used to provide the debugger's clock signal, while the SWDIO line is used for bi-directional data transfer. SWD interfaces play a key role in embedded system development, allowing users to debug and program target system chips without migrating them. The SPI_CLK line is a clock line in SPI communications, providing clock pulses to synchronize the transmission of data; the frequency of SPI_CLK can be adjusted to accommodate communication speed requirements; the frequency of SPI_CLK determines the speed of data transfer; high speed SPI communications require higher clock frequencies, but require ensuring accuracy of clock synchronization. Analog to digital converters are used to convert analog signals (such as rotation information and position information) to digital data, and in a ring mouse, ADCs are used to measure the angle or position of rotation and then convert this information to digital form for processing. ADCs are widely used in a variety of applications, such as sensor data acquisition, audio signal processing, etc., and accurate ADC design is important to accurately capture variations in analog signals. A four-phase decoder is typically used to measure rotation information and position information, which can identify the output of a rotating device (e.g., a rotary encoder) and convert it to a digital signal to determine the direction of rotation and the number of steps. Four-phase decoders are key components in rotary encoders and motor control applications for achieving accurate position and motion control.

An inductor is a passive electronic component for storing electric energy, and converts current into magnetic field to store energy through electromagnetic induction, and then releases the stored energy back to a circuit. The model of an inductor typically contains its inductance value, e.g. "2.2uH", which means that the value of the inductance is 2.2 microhenries, which determines the response speed of the inductor to current and the electrical energy storage capacity. The model of the crystal oscillator is X1E0002510059, which is a key component for providing accurate clock signals. Crystal oscillators use the crystal oscillation principle to generate stable clock signals that are used to synchronize various operations in electronic devices, ensuring accurate timing and data transfer. The frequency stability of a crystal oscillator refers to the accuracy and consistency of the clock signal it generates, and high quality crystal oscillators typically have very high frequency stability. The antenna is used for receiving and transmitting wireless signals, converting electric signals into radio waves or converting radio waves into electric signals, and in the finger ring mouse, the antenna is used for Bluetooth communication with other devices. The performance parameters of the antenna, including gain, frequency response, directivity, impedance matching, etc., affect the stability and range of the communication. Antenna designs often require radio frequency technology to be involved, including impedance matching, resonant frequency, and radio frequency power transfer of the antenna.
