PL2303HX PL2303 USB to UART TTL Cable Module RS232 Converter 4 Pin

This is a CH340G TTL UART 5V serial adapter, designed to allow adding a USB connection to your project.
In addition, this opens up the possibility of programming microcontrollers like the Arduino Pro mini.
This module allows you to connect your project, from programming small microcontrollers to a custom computer keyboard.
The module is ready for use of a UART connection.
This may require the installation of a driver; however, it is a standard driver distributed by Microsoft Windows Update, available in Linux and that can be configured in MAC OS.

Converter RS232/485/422 to Ethernet RJ45 has been designed for the industrial environment. It combines multiple functions including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. The module has an RS232/485/422 and Ethernet port (PoE function).Suitable for applications such as data acquisition, IoT gateway, IoT security. and smart device monitoring.

This converter has internal DC/DC power supply and full isolation between USB and RS485 output and enables to establish reliable and secure communication. It adopts the original FT232RNL and SP485EEN chip solution, provides stable communication with built-in galvanic isolation, lightning protection and anti-electrostatic protection, etc., it is an ideal choice for industrial control equipment and/or applications with high communication requirements.

This module equipped with a PCF8591 converter has a low current power supply and includes 8 bit CMOS data acquisition devices.
Your converter has four analog inputs, one analog output and one I2C serial bus interface.
It is supplied in the voltage range 2.5V-6V, analog voltage between the negative potential VSS and positive VDD. The control and data signals are transmitted on the two-wire I2C bi-directional bus to the transformed series.
The intensity of the ambient light can be converted into a digital signal thanks to its integrated photoresistor.
It allows access to eight PCF8591 converters on the same I2C bus without additional equipment. Converter Module AD-DA PCF8591 - Analog Voltage 2.5V-6V features:
- Supply voltage (between VSS and VDD): 2.5-6VDC

This product is widely used in radio modifications, cell phone flash, xbox360 flash detection, GPS, car, Flash, HDD repair, top box upgrade.
It can be used to download MCU types. Module MAX3232 Converter RS232 to TTL Port DB9 female features:

Connecting a 3.3V device to a 5V system is a challenge.
The bidirectional logic level converter is a small device that safely drops the signals from 5V to 3.3V and increases 3.3V to 5V at the same time.
This level converter also works with 2.8V and 1.8V devices. What really separates this logic level converter from our previous versions is that it can successfully set its high and low voltages and go up and down between them safely on the same channel.
Each level converter has the ability to convert 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side. The level converter is very easy to use. The board needs to be powered from the two sources of voltage (high voltage and low voltage) that your system is using.
