5V-3V IIC UART SPI and other 4-way level conversion module 4-way pin header

product description:
   Due to part of the microcontroller development board and equipmentIs 3.3Vjobsof,But also a single-chip development board and equipment, sensors, etc. areOf the 5.0VWork power, so when the two need to communicate, it appearedOperating VoltageInconsistent situation, so that users use itinconvenient. This productIs designed for this problem and to solve this problem. This module is in3.3V and 5.0V in different devicesProvides the feasibility,Played a bridging roleThe

Product features:
1. Four MOS transistors realize four -way bidirectional conversion of 3V and 5V levels.
2. Power input with anti-reverse connection protection, integrated 3.3VLDO, and can provide external current not greater than 150mA
3. With power indicator, It is clear whether it is working or not
4. It can realize the bidirectional conversion of 3V-5V level of bus signals such as UART, IIC, 1-wire, SPI, etc.

Module Features:

1,4ChannelOf high voltage logic and low voltage logicBidirectional conversion

2,4ChannelThe high voltage logic is converted to low voltage logicOne-way conversion

3,Module compatible breadboard, Can be inserted directly on the breadboard
