Quick Overview
This DIYables 8-channel bidirectional logic level converter safely shifts signals between 5V, 3.3V, 2.8V, and 1.8V logic levels in both directions on the same channel, making it easy to connect mixed-voltage devices without damaging them. It's designed for SPI and I2C signal levels, with 4 bidirectional channels on each side for safe interfacing of mixed-voltage sensors, displays, and modules.
The module comes fully presoldered with headers, so it's ready to use immediately on a breadboard or PCB without any soldering. Wiring is simple: connect HV to your high voltage supply, LV to your low voltage supply, and GND to a common ground, with two inputs and two outputs provided on each side for straightforward mixed-voltage system integration.
This listing includes 5 presoldered 8-channel level converter boards, each measuring 28 x 19mm, ideal for Arduino, ESP32, ESP8266, Raspberry Pi, and any mixed-voltage microcontroller project.
