+At [RF.Guru](https://rf.guru/), we employ this board for internal development and exploration of new product ideas. Given our focus on radio applications, we required a board with outputs that produce minimal noise.
 
 **Enhancements Include:**
 
-- Improved 3.3V LDO for reduced noise.
+- Improved 3.3V LDO for reduced ripple (less noise).
 - Incorporation of ESD protection and noise filtering on both the USB Data bus and the 5V DC input.
