The SigmaLink USBi is an all-in-one real-time programming interface.
MAIN COORDINATOR: Max Chan
The SigmaLink USBi is a low-budget real-time programming device for the freeDSP and other DSP boards from Analog Devices. It is a new PCB design based on a CY7C68013 chip.
It has the same features as the Analog Devices USB interface (EVAL-ADUSB2EBZ), such as changing parameters while already using the freeDSP or easy changes of the schematic in SigmaStudio. You also can write your program to the EEPROM.

Questions
How big is the SigmaLink USBi PCB?
It measures 64 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SigmaLink USBi use?
31 parts, built around the 24LC512-I/P, 74LVC2G66DP, LM1117-3.3 and MAX809S. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SigmaLink USBi KiCad files?
From the freeDSP/SigmaLink-USBi repository on GitHub, at the commit this page was made from: the board is SigmaLink-USBi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SigmaLink USBi design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
