It is the Third recording module developed , this version is distinctly improved in the acoustic fidelity relative to the first and second version.
- Built-in microcontroller serial communication interface
- 3V single-supply operation, low power consumption
- Multi-information processing
- Working current 25-30mA, to maintain current 1μA
- Information is not power to save 100 years (typical)
- High-quality, natural voice reduction technology
- 10 million times the recording period (typical)
- Automatic squelch
- Free adjustment of the clock chip, the external clock can be selected

The Sound Recorder Module uses the ISD1760 Chip to record and store voice signals. ISD1700 series recording chip is a kind of high integration, high performance chip. This module can be multiple recording, the sampling rate can be set to 6k or 8k by the on-board resistor. There are also some inside sounds to remind the user working state of the module, such as record beginning, record stopping, record erasing , etc. The recording data is stored in the FLASH, without any compression to ensure a good quality. You can easily control this module manually or by Arduino. There are some keys on the module including “REC”,”PLAY”,”EARSE”, you can control the module with these keys.

Yun Shield runs Open Source OpenWrt system and it is fully compatible with Arduino IDE v1.5.4 or later. Yun Shield is the ideally choice for Arduino Projects w Yun Shield is one of the most powerful shields for Arduino Board. Yun Shield is designed to solve the Internet connectivity and storage issue for Arduino Board. Yun Shield runs Open Source OpenWrt system (Same system as runs in Arduino Yun) and it is fully compatible with Arduino IDE v1.5.4 or later. Yun Shield is the ideally choice for Arduino Projects which require various internet connections and more storage.

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.

The SRF05 is an evolutionary step from the SRF04, and has been designed to increase flexibility, increase range, and to reduce costs still further. As such, the SRF05 is fully compatible with the SRF04. Range is increased from 3 meters to 4 meters. A new operating mode (tying the mode pin to ground) allows the SRF05 to use a single pin for both trigger and echo, thereby saving valuable pins on your controller. When the mode pin is left unconnected, the SRF05 operates with separate trigger and echo pins, like the SRF04. The SRF05 includes a small delay before the echo pulse to give slower controllers such as the Basic Stamp and Picaxe time to execute their pulse in commands

HX711 is a precision 24-bit analog to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32.
