STM32 Nucleo pack LoRa™ LF band sensor and gateway
TIDA-01234 is a 24W high efficiency (94%) low-cost asynchronous boost reference design for automotive LED applications based on LM3481-Q1.
This reference design is suitable for automotive high-intensity lighting systems such as headlights and taillights, as well as interior LED lighting systems. It is designed to operate over an input voltage range of 6V to 18V and is capable of driving multiple strings of 6 to 7 LEDs in series (16V to 24V) at a constant current of 1A. This reference design supports analog LED brightness control and output open circuit protection. In a boost-to-battery configuration, the input voltage can be above, below, or equal to the desired LED string voltage.

STM32L4+ Discovery kit IoT node, low-power wireless, BLE, NFC, WiFi
It is mainly composed of the basic functions and structure of the professional electric energy measurement chip ATT7022B and the single-chip computer MSP430F149 system. In terms of hardware circuits, the electromagnetic compatibility of the circuit is fully considered in the circuit design. A more reliable power supply for electric energy meters is designed to improve the ability to withstand lightning strikes. And it is proposed to use EPROM to store data in order to achieve the purpose of simplicity and security. In the particularly critical communication unit of the electronic energy meter, multiple communication methods such as serial communication and wireless communication are designed to connect scattered electricity meters into a network to achieve centralized control and remote meter reading functions. In addition, a GPS module is designed to locate the coordinates of the collection point.
