| | We are a manufacturer of electronic components, electronic modules for a large number of products.We are the factory!With more than 10 years of PCB development experience, the product quality is good, the price is excellent.A large number of wholesale sales of global buyers, welcome to purchase.
This product is a level conversion module, not a power conversion module! Must connect 5V power supply to work normally! Don't buy if you don't understand! Product features:
1. Four-channel bidirectional conversion of 3V and 5V levels is realized with four-channel four-mos tube.
2. Power input with anti-backconnection protection, integrated with 3.3VLDO, and can provide no more than 150mA of current
3. With power indicator light, it is clear whether it works or not
4. Bi-directional conversion of 3V-5V level of bus signals such as UART, IIC, 1-Wire and SPI can be realized
