DALI 2 lighting control solutions use the DALI 2 standard based on Digital Addressable Lighting Interface (DALI) technology. This solution uses Nuvoton's self-built DALI 2 code base to develop various DALI 2 devices. The DALI 2 code base complies with the DALI 2 standard. Nuvoton is now a member of DiiA and has experience in DALI 2 product certification.
This DIY LiPo super charger can charge a single LiPo battery and protect it from overvoltage, overload and short circuit. In addition, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an "eFuse" IC with a maximum output current of 1.52 A at 5 V and 0.76 A at 12 V. The charger part of the circuit requires a +5V power supply, which can be connected via USB-C, or simply solder two wires to pads on the PCB. Additionally, other connections can be soldered to pads on the PCB or use individual pin headers.

This project uses the LSM6DSOX+STEVAL-MKI109V3 mode for preliminary sensor learning and research, mainly from training the acceleration sensor to detect vibration and recording vibration waveforms, training the gyroscope sensor to detect the vibration direction and offset, and recording the waveform for analysis; combined with the acceleration sensor and the action data of the gyroscope sensor can determine the vibration intensity and direction of the wind turbine tower under various working conditions; in practical applications, the LSM6DSOX sensor is combined with the low-power chip STM32L010RBT6 chip, and the main control board on the local side leads to an alarm relay. The outlet is used for alarm output on the wind turbine tower side. It is connected to the wind turbine scada system through 485 serial port communication to upload the recorded data on the local side to provide real-time feedback on the working status of the wind turbine tower. It can be used to analyze the vibration reverse and wind turbine tower vibration. Swing direction recording can also record and analyze the natural frequency of the wind turbine tower under normal conditions and the natural frequency during faults. The multi-faceted data forms a wind turbine tower disaster warning system that can be sensed in advance;

Compact 27W USB Type-C Power Delivery 3.0 with PPS adapter reference design
Chhavi is a tiny, wireless, touch capacitive fingerprint sensor with high-end security features, support for ultra-low power operation and optional NFC connectivity. Its open source firmware is fully compatible with the Arduino IDE. Chhavi is powered by ESP32 and features an FPC BM-Lite fingerprint sensor by Fingerprints, giving you and your projects access to the excellent biometric hardware found in many smartphones. Unlike optical fingerprint sensors that are large and power-hungry, this capacitive biometric sensor is small, accurate, and energy-efficient. During our design process, we determined that NFC communication would be a powerful feature for many of the same applications that might require a high-quality fingerprint sensor, but we could not find a major ESP32-driven NFC controller. So we built one into Chhavi as an optional feature. We've also added an optional battery to simplify installation and facilitate mobile deployment. The result is a tiny device with a cutting-edge fingerprint reader, Wi-Fi and Bluetooth capabilities, as well as support for NFC and battery power when needed.
