The RS-232 is a standard and very popular protocol for communication between two devices. It is a full-duplex protocol which means it can receive and send data at the same time, and data is sent at voltages from + 3V to + 15V for a digital “one” and from -3V to -15V for digital “zero”. This provides a more secure environment for data transmission which is resistant to noise or interference, which is why the RS-232 is often used in industry. This module converts serial communication to RS232.
• Communication lines: TX, RX
• IC:232 MAX
• Voltage: 3.3V – 5.5V

This logic level converter board module gives us a translation of logic level between two signals. In layman’s terms, if we take a signal with logical “unit” on 5V convert into a signal which logical “unit” has on 3.3V this module will help us. Something like this is useful in this case if we want to achieve communication between two devices from whom one works on 5V and the other on 3.3V, or any other combination of voltages. Directly connecting we would “burn” a device that works on 3.3V and a module gives us to avoid that.
• Max. voltage: 30V
• Number of channels: 4
• Dimensions: 22 x 22mm
This module allows you to connect a Dasduino, or similar microcontroller, to a RS-485 communication protocol. The RS-485 is used to send data over long distances (up to 1200m) at 20Mbps and in high-noise environments, such as industrial. The module works on 5V and requires between 120μA and 500μA of current.

CAN Transceiver (Controller Area Network) is a network technology that enables fast communication between microcontrollers, and is the most commonly used standard in cars. Our CAN breakout uses an MCP2518FD CAN whose communication between microcontrollers takes place on SPI protocol. In addition there is a CAN transceiver. This breakout allows use of both standards (CAN 2.0B and CAN Flexible Data (FD)). Access to the CAN bus is possible via CANH and CANL pins on the screw terminal. The 120ohm terminator resistor is also located on the board and can be connected to a jumper.
• Standards: CAN 2.0B i CAN FD
• Voltage: 2.7V i 5V
• Current: from 10uA to 12mA
• SPI interface

The IR receiver is a device that detects the modulated IR radiation emitted by the remote controls. The IRM-56384 detects IR radiation on a standard frequency of 38kHz and outputs signal to its output pin, which can be read with a microcontroller. Thus, it enables project management via the remote control.
The Bluetooth audio module allows you to stream, ie. transfer audio from a device (such as a cell phone or laptop) to this module via Bluetooth.

To use this module, drivers from the official website must be installed.
Have you ever found yourself wanting to connect more than one I2C device to a single controller and couldn’t because they have identical I2C addresses? There you have it, I2C multiplexer (I2C MUX) allows you to use up to 8 devices with the same address on the same bus! If we mention that TCA9548A, the IC on which this breakout is based, has three adjustable pins for the I2C address, which means a total of 8 possible addresses. We can reach 64 devices with the same address on the same bus. For example, it is possible to connect 64 BME680 sensors that are read by only one microcontroller.
This adapter is particularly practical because it enables multiplexing of easyC devices.
