8 Channel 5V/3.3V IIC UART SPI TTL Logic Level Converter for Raspberry Pi 8 channel level conversion module
Since the Raspberry Pi is 3.3V GPIO, so take the conventional 5V sensor inconvenient. Therefore, this product to achieve 8-channel high-voltage and low-voltage logic bidirectional logic conversion, two-way conversion between Ax and Bx.
Conversion level range:
Instructions :( with 3.3V, 5V system conversion, for example)
VCCA access Raspberry Pi 3.3V power supply
VCCB connected to 5V power supply (may be an external 5V power supply)
GND negative one, two power supply common ground
Ax input Raspberry Pi 3.3V TTL level, Bx output 5V TTL level sensor module
Bx Input 5V TTL level electronic modules, Ax output Raspberry Pi 3.3V TTL level
