Bluetooth

Bluetooth , which is based

on IEEE 802.15.1, was

developed for the purpose

of sending larger amounts

of data quickly from

computers to portable

handheld devices. Key

features include high

data rate, frequency

hopping, very small form

factor and modest power

consumption.

Panasonic offers a new

Bluetooth RF module

product line that makes

connectivity between

mobile devices easily

implemented, creating a

seamless data chain from

sensors to the Web.

Just another way we’re engineering

a better world for you.

to four times greater than

copper, PGS is extremely

Hot 100 products of 2012

53 EDN’ s technical editors each year cover

thousands of products, so it takes

something special for a product to stand out

from the pack. The offerings listed here did

just that, warranting their inclusion in the 2012

edition of EDN’ s Hot 100 products.
