Introduction:

Specifications

Product Overview:

This module is designed specifically for convert the GPIO electric level of Banana Pi. It can convert 3.3V electric level to 5.5V electric level. That makes the Banana Pi compatible 5V peripheral. Modules are drawn twice a 5V Vcc and 3.3V Vcc; module IO are all below the left side of the 5V level IO, the right of all to 3V level IO. It is connected via cable 2 * 13 and banana pie GPIO port, and then plug in the breadboard module can be used.

Produce Feature:

-- Convert 3.3V GPIO to 5V GPIO

-- 3.3V GPIO and 5V FPIO classification

-- Can be used in breadboard

-- Use TI TXB0108 chip

Port:

-- 5V Vcc

-- 3.3V Vcc

-- 5V GPIO

-- 3V GPIO

-- Banana Pi connect port

Product Parameters:

-- Working voltage: 1.65V-5.5V

-- Drive current up to 50mA

-- Low Power Consumption, 4-μA Max Icc

-- −40°C to +85°C operation

Typical Application:

-- Convert electric level

-- Breadboard test

-- DIY hands-on experiments

How to use:

-- connect the module to Banana Pi, if it’s OK, the PWR LED will light; then insert the module to breadboard and enjoy it.

Schematic diagram:

Testbench:

-- Connect the module to Banana Pi;

-- Set all of the GPIO of Banana Pi to OUTPUT mode;.

-- Set all of GPIO to High level, find the voltage is 5V or 3.3V

-- Set all of GPIO to Low level, find the voltage near 0V.;

-- Finish test
