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.

- Dimensions: 16x9mm

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.

6-pin/10-pin Kanda DIL adapter features:
- Connector for Usbasp Programmer AVR Atmega8 Atmega128

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

The ADS1115 is an external 16-bit ADC + a built-in programmable gain amplifier (or PGA), which can be very useful for certain Arduino and ESP8266 projects. This is ideal when more resolution or more analogue pins are required. You get better accuracy, as well as relieving the processor of this burden.

Ideal to connect TTL RS232 devices to your PC through the USB port. RS232 USB to Serial TTL Adapter Module - USB to Serial PL2303HX PL2303 features:
> - Compatible PL2303 controller
- 5 pins: 3.3V, 5.0V, TxR, RxD, GND
- Heat shrinkable insulating cover
- Led data transmission indicators
- 2.5A self-recovery protector fuse
- Supported OS: Win ME, Win2003, Win XP, Vista, Win 7
- Weight: 40 gr. (approx.)

This FTDI breakout is a super small board with a standard FT232RL USB to serial IC circuit. The pinout fits FTDI cable making it compatible with any Arduino or Arduino compatible 5V boards.
