Bidirectional logic level converter allows the signal to be pulled down from 5V to 3.3V, or up from 3.3V to 5V. It can also work with 1.8V and 2.8V levels. Allows to convert 2 communication lines.
A very useful miniature device for interfacing modules with controllers if they have different logical unit voltages. The device is based on two MOSFET transistors, thanks to which the converter received a bi-directional logic level matching circuit on two channels, it can both increase and decrease signals, these functions are used to connect UART, I2C and SPI interfaces. The board also has a linear buck regulator up to 3.3V with a current up to 500mA.
Connecting to the board:
A high voltage logic signal (for example 5V) is connected to the ASCL and ASDA pins
To BSCL and BSDL pins - low (for example 3.3V)
The AVCC input is supplied with the converter supply voltage and is the input of the linear stabilizer
BVCC output - linear stabilizer output
Common disadvantage - AGND and BGND
Now the high voltage logic 1 on the ASCL pin will be converted to a low voltage logic 1 on the BSCL pin.
Conversely, a low voltage logic 1 on the BSCL pin will be converted to a high voltage logic 1 on the ASCL pin.
Dimensions: 17 x 12 mm
