Receiver board for Wireless Power.

receiver module coupled with a 7100-FT1235M transmitter unit allows you to produce wireless energy transfer systems. The receiving unit, based on the integrated P9025AC of IDT, receives the voltage induced at the terminals of the receiver coil straightens to obtain the necessary current for both the card itself that for the load, providing voltage across the terminals vrec and GND. The receiving module is equipped with a strip 7 at step terminals 2.54mm.
Ideal to be used with Arduino, small robots, locators and more generally for all those systems where it is necessary to transfer energy without contact.

Dimensions: 24 x 21 mm

Note: The card is supplied assembled. The coil for Wireless Power Receiver is not included and is available separately

The ability to transfer electricity through the electromagnetic waves was demonstrated for the first time in 1890 by Nikola Tesla, that perhaps did not imagine what would have been appreciated to the present day. The technique is easy, but to make this technology more efficient, less cumbersome, especially for higher power of those paltry available in the past, it is the real challenge, which becomes more difficult when you have to make economic and miniaturized solutions also introduce them to multiple devices small. IDT (Integrated Device Technology), California-based company a pioneer of this technology, has provided documentation and products to achieve miniaturized systems to be integrated in many fields of wireless charging of batteries.

To ensure compatibility between transmitters and receivers, it was created the Wireless Power Consortium (WPC) that created a standard (Qi) ad hoc; This consortium was created in 2008 and consists of Asian companies, European and American. The WPC defines the type of inductive coupling, understood as the configuration of the inductances and the communication protocol to be used; in this way each device that complies with the specifications of the WPC standard is able to operate with another standard product also of different brand, ensuring interoperability and above the power use when away from home. The inductances allow, in addition to the transfer of energy, to realize also the communication channel between the receiver and transmitter. The standard defines the systems capable of transferring non-contact energy, typically with power up to 5W and with distances up to 5mm; the adjustment of the output voltage is realized by a digital control that allows to use the communications exchanged between RX and TX to inform this' last entity of the power required by the load.
