8-channel high-voltage and low-voltage logic bidirectional logic conversion, two-way conversion between Ax and Bx.
Conversion level range: 1.8V-6V.
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.
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.
Instructions :( with 3.3V, 5V system conversion, for example)
