![]() ![]() In the above circuit, for logic 1 levels, when 3.3V is applied to the left 3.3V_Logic pin, 5V appears on the right 5V_Logic pin. Transistor Bidirectional Level Shifter 2N7000 Bidirectional Level Shifter Power for the pressure sensor module must be taken from the Arduino 3.3V pin.Īlternatively a transistor such as a 2N7000 N-Channel MOSFET can be used to make a bidirectional level shifter as shown below. Arduino Due GY-BMP280-3.3 Pressure Sensor Module I☬ Wiring Diagram I☬ Wiring to 5V Arduino UnoĪ bidirectional level shifter module can be used to connect the 3.3V GY-BMP280-3.3 module I☬ pins to a 5V Arduino such as an Arduino Uno or Arduino MEGA. Module pin 6 to module pin 1 (or 3.3V) – this sets the I☬ address to 0x77īelow is the wiring diagram as described above.Module pin 4 to Arduino Due SDA (pin 20).Module pin 3 to Arduino Due SCL (pin 21).I☬ Wiring to 3.3V Arduino DueĪ GY-BMP280-3.3 pressure sensor module can be used directly with a 3.3V Arduino such as an Arduino Due. Specific Arduino pins must be used for hardware SPI. Hardware SPI refers to using the actual hardware SPI device of the microcontroller chip on the Arduino. This enables a SPI device such as the pressure sensor to be connected to any Arduino pins. ![]() Software SPI refers to using the Arduino SPI driver to emulate SPI hardware using "bit banging".
