THE ALPHABET PROJECT - professional Arduino & Raspberry PI shields

 

OUR VISION:

Just one thought- bringing to you more powerful shields, borne from professional designs, at affordable prices. In this way, "THE ALPHABET PROJECT - professional Arduino & Raspberry PI shields" becomes reality.

HOW WE DO THAT?

There's very simple: just porting some successful of our professional designs in a way to fit the DYI/hobby and small/medium gadget projects market niches.

WHY ALPHABET?

When you comunicate, first you'll need to know the words, but what you do if you did not "learn" the alphabet before? This is our task - bringing the alphabet's letters to you. Use our powerful "letters" to build your "words", then "communicate" using them.

European Award given to R&D Software Solutions

HOW DIFFICULT IT IS TO USE THE ALPHABET?

Any of our shields has downloadable commented and structured examples. Playing with this examples and expanding the code you can obtain interesting applications. All hardware configurations are well documented.

ABOUT US:

We are a gang of guys having same passions: electronics, software... Since 2001, we are working as solution provider, incorporating electronics and IT technologies with our original concepts and ideas into smart and cost-effective solutions. Deeply involved in innovation, R&D Software Solutions received in 2006 as acknowledgement for its innovative ideas, the GST SSC Bronze Award between competitors like: IBM, Computer Associates, 17 European Universities and a batch of SME.

A   a-gsm shield

ARDUINO and RASPBERRY PI compatible GSM/GPRS/DTMF/SMS shield : a-gsm shield
it is one ARDUINO & RASPBERRY PI compatible GSM / GPRS / DTMF / SMS shield. Sorry... not "one", "the one"! The combination of supported features, some of them unique on market, make it the perfect match for anyone needs. Integrated antenna and U.FL connector for extenal one(YES!), embedded USB interface(mmm, good!), DUAL SIM(changing active SIM and network "on the fly"), micro SD adapter (maybe some data must be stored somehow), two regular 3.5mm stereo jacks mic and speaker (700mW-RMS!!!) are only some of them.
I almost forget: we embed into a-gsm shield one switching power supply that makes possible the usage of the Arduino / RasperryPI 5V/Vint output as powering source. Also, you can use the a-gsm shield as GPRS modem connect via USB with your computer, or you can use your phone adapter as power supply for the shield(uUSB B).;) We've tested all this powering schemas(especially for powering via Arduino 5V/Vin pins) until -95dB signal level and...IT IS WORKING!(...anyway, you use some decent power adapter for your Arduino / Raspberry!?)
Read more about a-gsm shield, buy it, download code examples (C for Arduino and Python for Raspberry PI) and start your DYI project with wireless communication....and remmember this: if you are involved in development of a small/medium size project requiring robust and reliable communication performance, a-gsm series is the solution.
