About us: DLP Design, Inc., a privately-held corporation based in Allen, Texas, has been in business since 2000. Our goal is to provide hardware and software solutions that make it easy for engineers and hobbyists to interface to a host computer via USB. Our products include USB adapters, USB security dongles, development and evaluation boards, temperature/humidity sensors and RF/RFID products. Our signature line of USB adapter boards (and their royalty-free drivers) offer customers a variety of options to interface with serial, parallel, single- and dual-channel platforms and multiple mechanical interfaces to accommodate numerous types of connectivity. Typical implementation requires a minimal learning curve and presents a surprisingly fast time to market.
