LoFive-R1
Product Description

The new LoFive R1 features the latest SiFive FE310-G002 RISC-V MCU. This new G002 version of the FE310 adds an I2C port and a second UART over its predecessor, which makes it much easier to add sensor and peripheral interfaces. The PCB has been updated as well. It now has castellated edges in case you want to drop it on another board via SMT instead of through-hole. If the first LoFive was a little too "wild west" for you, LoFive R1 is a much friendlier introduction to the RISC-V ecosystem that seems to be growing in popularity on a daily basis.

How it works

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds. Please see our FAQ page for more details on our billing process.

    what is the difference between the e31-G000 and the e31-G002? I looked on the datasheet and didn't see anything jump out at me

    The main differences in our book is that the G002 has an I2C port and an additional UART. Qwerty could probably point out more differences.
