XTRX Prototype Update

Life of a hardware company is never easy. Every error in hardware leads to significant amounts of lost time and money. You can’t just roll-out a hotfix to fix an issue. Which is why we’re taking a rigorous approach to testing our hardware before releasing it to the public. But today’s update is not about testing. Read the full update.
