This device uses an AD620 as an amplifier that is capable of amplifying small voltage signal (e.g. µV) AC or DC. By adjusting the on-board potentiometer, the magnification can be adjusted to go as high as up to 1000 times. This module has a low voltage offset, great linearity, and also, an adjustable zero potentiometer to improve its accuracy.

This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65 to 3.6 VDC while it tracks the VCCA supply and the B ports supporting operating voltages from 2.3 to 5.5 VDC while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes.

This miniature latching pushbutton is a ON/OFF switch that can be mounted and soldered on the included breakout-board (which is breadboard compatible). The two holes on the sides allow for mounting the breakout-board using M3 screws. The way the locking mechanism works is that once the button is pressed it locks and stays in the locked position. Pressing the button once again will unlock the mechanism and release the button.

This is a special FTDI cable, usually you can get either 5v or 3.3v based on the FT232R chip. This means that the data and power cable is only 5v or 3.3vdc. This product offers the red and black cable to provide 5VDC and the data lines white, green, yellow and blue run on 3.3vdc.  This cable is excellent for running your raspberry pi that requires 5vdc to power on and 3.3vdc for logic pins.

This product is an excellent choice for those who don’t have enough memory space for their microcontroller based projects. An EEPROM acts like a memory card where you can save data onto the device up to 256KB and it will retain that information even when power is lost! Simply connect four wires to get this device up and running by I2C protocol. It is recommended to run the Arduino i2C scanner to code to find the address of this device. You can attach more EEPROM and address them for more memory.

This is a simple board with two Seven Segment Display soldered onto the board and some through holes for soldering pins. This board has two shift registers, SM74HC595D to drive each seven segment display reducing the amount of wiring you need to have the displays functional. The only wiring you need to do is supply 5v, GND, SDI to pin 8 on Arduino, SCLK to pin 10 and LOAD to pin 9 on Arduino. You can also daisy chain These displays by connecting P2 to the new board P1.

The FT245 EVAL BOARD provides a high-performance cost-effective solution for USB TO 8-BIT FIFO. It is based on the FT245RL chip and will hopefully allow to try out the full potential of the FT245 device before using it in your prototype. The FT245RL is a USB to parallel FIFO interface device which simplifies USB to FIFO designs and reduces external component count by fully integrating an external EEPROM, USB termination resistors and an integrated clock circuit which requires no external crystal, into the device. It has been designed to operate efficiently with a USB host controller by using as little as possible of the total USB bandwidth available.
