LilyPad Coin Cell Battery Holder CR2032 [B067]


* Specs

This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the LilyPad slide switch board, so it's not easy to accidentally turn off or on.

Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (two positive and two negative) for sewing into your project.

VS1053B MP3 Music Shield (VS1053B) [B119]


*GitHub https://github.com/rdiot/rdiot-b119.git

* Specs

This MP3 shield board is designed based on VS1053B from VLSI.

using this shiled you can plug in your arduino UNO/MEGA direcly as showing in pic,

dont' need need to hook up with jumpers,

it's becomes more easy to play music compared with the tiny mp3 breakout board.

VS1053 is a versatile MP3 codec processor that is capable of decoding a variety of music formats,

including Ogg Vorbis/MP3/AAC/WMA/MIDI audio.

For the best headphone listening experience,

the VS1053 includes EarSpeaker spatial processing which

accurately simulates how a room with stereo loudspeakers would sound.

In addition to being able to decode all major formats,

VS1053 is capable of recording in Ogg Vobis file.

With the TF card slot on the other side of the board,

you can play mp3 files from TF card using this breakout.

It is easily to drop it in your project or make a mp3 player using your Arduino or other microcontroller.


Features Can play a variety of music formats,

support for OGG encoding real-time recording SPI interface,

the control signal lines are led out A headphone and stereo output

A microphone for recording A line_in input interface

Power indicator 3.3V and 2.8V of LDO chip AMS-1117 on board,

provides up to 800mA current

A single power supply: +5 VDC 12.288 Mhz crystal TF cart slot.

Arduino Nano Terminal Adapter Board [B080]


* Specs

This is a terminal adapter for Arduino Nano. It lables for Arduino Nano version 3.0, however you can still use this adapter for the older version (just have to remember that A0-A7 are in the reverse order). You can use this adapter to easily hook up Arduino Nano to an outside world via hook up wires.

Funduino Nano Shield (Funduino-NANO-006_V3) [B026]



* Specs

This Nano Mult-Function expansion board is designed specially for Arduino Nano, solve the problem of wiring confusing when a variety of sensors connected.

Lead out all digital IO port and analog IO port, each one with standard positive and negative power interface.

Lead out the I2C interface of mainboard for convenient connection.

Increasing the DC power supply interface. Nano USB interface supply current is actually only 50MA, to bring high-current devices, such as the steering, is obviously insufficient. So in the DC power connector provide external power supply to ensure the stability of equipment operation.
