The design is based on the SensorTile.Box kit, which is set to expert mode for direction change detection (using a gyroscope), close to the practitioner's lower abdomen; the LIS25BA bone conduction sensor collects and identifies the vibration signal of the user's breathing status at the nostrils. The signal output is also connected to the central main control circuit. The optimal compliance judgment for monitoring the breathing process coordination during the entire exercise process and the corresponding voice prompt information broadcast are made by the central main control circuit.
The USB Type-C™ and Power Delivery (PD) MicroDock Evaluation Module (EVM) provides a complete USB Type-C dock reference solution including audio, USB data, power delivery and video. The EVM has a small 2-inch × 4-inch form factor and supports both sourcing and sinking power capabilities through the USB Type-C PD host port. Video output capabilities include DisplayPort and HDMI.
30 W USB PD 3.0 Power Supply with 3.3 V–16 V PPS Output Using InnoSwitch3-PD PowiGaN (INN3878C-H804)
The TWS headset charging bin solution developed based on ML51 mainly has two major functions: data communication with the headset and charge and discharge management. Data communication is carried out with the headset through the pogo pin to realize pop-up windows and other functions that require data communication; the battery charging management unit has built-in lithium battery overcharge, over-discharge, short circuit, over-current and other protection functions, making the system stable and reliable.
Freedom development platform for Kinetis ® K66, K65 and K26 MCUs
This shunt-based, isolated current measurement unit enables high-precision current measurement without the use of current transformers (CTs). Isolation is achieved through the AMC1304 which integrates high voltage isolation and a Delta-Sigma modulator . This solution avoids the need to use CTs, which is highly valued by customers as it reduces board size, product weight, crosstalk and EMI in the system, and reduces mechanical requirements by replacing CTs with shunts. problems, potentially extending product life.
NXP's FXPQ3115BV biomedical precision pressure sensor ecosystem includes demonstration kits, sensor shield development boards and breakout boards.
This advanced motor implements closed-loop speed control to maintain precise RPM across load torque profiles. The DRV5013 Hall-effect sensor senses the magnetic rotor position, and the DRV8308 controller determines when to drive the CSD88537ND FET that energizes the coil . Without the use of a microcontroller or firmware, the sinusoidal current minimizes noise and torque ripple, maximizing motor performance.

Brushed motors are a relatively popular motor design option due to their low price and simple control scheme. A brushed motor has a wound rotor and a permanent magnet stator. The motor is commutated via a conductive ring: this ring is connected to the rotor, which uses a brush to scrape against the commutator ring, thus commutation is achieved. Therefore, the direction of current flowing through the motor can change depending on the brush orientation and different commutation rings. Simple direction changes and speed control changes can be quickly and efficiently implemented on brushed DC motors using an H-bridge. An electronic driver is required to control the motor current in a brushed DC motor. The electronic drive circuit contains a power stage with a two-phase inverter (to meet the required power intensity), a microcontroller for implementing motor speed commands and fault handling, a current sensing function for motor start/stop protection, for control Gate drivers for two-phase inverters and power supplies for microcontrollers and other low-voltage devices.
