We have an update from our manufacturing partner: the HiFive1 Rev B are rolling off the line and getting packaged up. We will be shipping out the HiFive1 Rev B campaign orders as quickly as possible and should be wrapped up before the end of April. When your order ships, you will receive a shipping confirmation email from Crowd Supply. If you need to update your address, you can do this by logging in to your Crowd Supply account.
