SAVVY-V is the culmination of two years of thinking about and designing a RISC-V development board that is both high-end and flexible. I’m striving for tidy component placement and minimal cable mess, while supporting a wide range of features and use cases:

Features & Specifications

Comparisons

Microchip’s PolarFire SoC is just now becoming available. How does SAVVY-V differ from the Icicle Kit and PolarBerry, which use the same SoC? SAVVY-V has more DDR memory (4 GB for LPDDR4 rather than 2 GB, and additional LPDDR3 for FPGA logic), more storage (up to for eMMC 5.1), and high-speed (5 GT/s or 4 Gbps) USB Type-C to connect between SAVVY-V or expansion boards. Of course, SAVVY-V will be correspondingly more expensive as well, though I don’t know the exact pricing yet due to the fact Polarfire SoC pricing is not yet publicly available. Moreover, some custom requests on memory capacity and SoC logic density (25K, 95K, 160K, or 250K logic elements) and speed (standard or 15% faster -1 speed grade) will have different pricing.

Stay in Touch

As I make progress on the board design and eventually make and test prototypes, I’ll post updates on this page. You can subscribe to updates by clicking the big button at the top of the page. You can also get in touch with me directly, and I encourage you to check out the Flexible Open Source Hardware for RISC-V (FOSOH-V) LinkedIn group I created.
