This is TDA7297 2x15W Digital Audio Amplifier, fits for Bookshelf speakers, CRT televisions, radios, and other small amplifiers

The SainSmart AD9851 is a highly integrated device that uses advanced DDS technology, coupled with an internal high-speed, high performance D/A converter, and comparator, to form a digitally-programmable frequency synthesizer and clock generator function. When referenced to an accurate clock source, the AD9851 generates a stable frequency and phase-programmable digitized analog output sinewave.

• 2 sine wave and 2 square wave output
• AD9851: 0-70MHz
• After the 20-30MHz frequency harmonics increases, the waveform will be less and less clean
• Square Wave: 0-1MHz
• Low-pass filter with 70MHz, so the waveform better than SN
• Parallel and serial data input can be selected via a jumper
• DA produced the benchmark pin (PIN12) leads for easy adjustment to do the magnitude of the output waveform Application
• Comparator reference input voltage generated by the variable resistor, the resistor can be adjusted duty cycle square wave of different
• AD9851 module Using 30MHZ Active crystal
• AD9851 Clock frequency up to 180MHz, AD9851 has 6 octave

The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs

• It can measure the static acceleration of gravity in tilt-sensingapplications, as well as dynamic acceleration resulting from motion, shock, or vibration
• Bandwidths can be selected to suit the application, with a range of 0.5 Hz to 1600 Hz for the X and Y axes, and a range of 0.5 Hz to 550 Hz for the Z axis.
• Tiny, low power consumption

Want more SainSmart Flexible TPU at a favorable price? We introduce you 2kg/4.4lb value pack. Same quality with more filament in a roll. 

• [Flexible and High strength] 95A hardness is similar to an o-ring. High abrasion resistance and low compression compared to rubber
• [Resistant to chemicals] resist oil, grease and etc. Durable performance even in the chemical harsh environment.
• [Easy to print] Excellent adhesion on heat bed, not necessary for extra adhesion like tape. Compatible with most Prusa i3 3D printers in the market. With bowden extruder needs to print slowly. 
• [Great for end-use parts or models] Can be used to print as functional parts or standalone prototypes. Like RC parts, case, or engineer design prototypes.

This is a DIY extruder kit which is original replacement parts for CR-10 series 3D printers.

• Better mechanical design, which makes it easier to feed filament.
• Unlike the original plastic extruder，this aluminum repalcement will be more stable and durable.
• Specially desgined for 1.75mm filament

The SainSmart MEGA 2560 Board is a microcontroller board based on the ATmega2560.

It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The SainSmart LCD Keypad Shield includes a 16x2 HD44780 White on Blue LCD module and a 5 push button keypad for menu selection and user interface programming.

Fully assembled. On-line Arduino tutorial and example code. Compatible with Arduino Uno, Mega, Duemilanove. Uses digital pins 4 - 10, and analog pin 0.
