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.

This support is a lilypad button to sew clothing or anything else you can dream of.
Lilypad is a wearable E-textile technology developed to have large connection pads to attach to clothing. Lilypad Button Board features:
- Density of the PCB: 0.8 mm
- Size: 8x16 mm
- 1 LED included

The LilyPad Arduino USB is a microcontroller board based on the ATmega32u4.
It has 9 digital input / output pins (of which 4 can be used as PWM outputs and 4 as analog inputs), an 8 MHz resonator, a micro USB connection, a JST connector for a 3.7V LiPo battery and a power button. restart
It contains everything necessary to support the microcontroller; simply connect it to a computer with a USB cable or a battery to start.
The LilyPad Arduino USB differs from previous LilyPad cards in that the ATmega32U4 has built-in USB communication, eliminating the need for a separate USB to serial adapter. This allows the LilyPad Arduino USB to appear on a connected computer as a mouse and keyboard, as well as a virtual serial / COM (CDC) port.
