About Us

Our first MFI certified Serial Cable (2010)


In 1995 we founded Keyspan and began developing accessories for the Macintosh.

From 1996 to 2008 we engineered more than three dozen accessories for the Mac, PC and iPod. We shipped more than 2 million units worldwide and provided products on an OEM basis to companies such as Apple and Lantronix.

We sold the Keyspan brand to TrippLite in 2008. Following the sale of Keyspan we launched Redpark Product Development and turned our focus to the iPhone and iPad.

Initially as Keyspan and later as Redpark, we’ve participated in Apple’s “Made for iPhone” (MFI) licensing program for more than 15 years.


Redpark engineers and markets connectivity accessories for the iPhone and iPad.  We serve companies throughout the world.


Our team consists of hardware, firmware and software engineers located in California. Our products are manufactured in China through partnerships that have existed for more than a decade.

We offer Redpark branded accessories that solve many of the connectivity needs facing companies that use iPhone and iPad.  

We also deliver custom cables and other custom products in a “turnkey” fashion (handle all aspects of development and use our Asian manufacturing relationships to build the product for you).
