Running at up to 320MHz, the RED-V Thing Plus and RedBoard feature a 32-bit RISC-V core in Feather- or Arduino Uno-like form factors.

SparkFun has officially launched the RED-V Thing Plus and RED-V RedBoard, a pair of Feather-compatible Thing Plus-footprint and Arduino Uno-format development boards based on the SiFive Freedom E310 RISC-V microprocessor core - making them, the company claims,“completely open source [...] from hardware to ISA.”
“The SparkFun RED-V (pronounced ‘red-five’) Thing Plus is a low-cost, development board in our popular Thing Plus footprint and adds in the Freedom E310 core and RISC-V instruction set architecture (ISA),” SparkFun’s product announcement explains. What sets the RED-V Thing Plus apart is the completely open source approach from hardware to ISA. That means anyone can make full use the microcontroller without requiring royalties, licenses, or non-disclosure agreements.
