This bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 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 you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

Description The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range.

This development board uses the ATmega48 microcontroller for convenient interfacing with the NRF24L01 module. It also features an I2C communication interface that can be used for communication with other microcontrollers such as Arduino or for connecting other peripherals directly to this board. This module comes programmed with an I2C to SPI bridge which implements a convenient RF communication solution. With this module, users do not need to understand the NRF24L01 communication protocol which makes the building of NRF24L01 wireless application easier. This improves the efficiency of the project development process. This module is perfect for robots, remote controls, and remote sensing applications.
