+This repo contains the source for the both the PC application (written in C#) and the firmware (written in C) for the QA350. The firmware is based on the MSP430F5529, and is built under Release 8 of Code Composer Studio. 
+
+The QA350 provides high-resolution voltage measurements across 2 ranges: +/-5V and +/-50V. In the +/-5V range, the QA350 deliver uV resolution. In the +/-50V range, the QA350 provides 10 uV resolution. The QA350 is NOT for use on high-energy circuits or anything that is connected to the mains. It is designed for measuring very high resolution sensors and other low voltage applications where precision is required. 
+
+As of release 1.70, the QA350 can support true RMS measurements, with a 3 dB bandwith of 4 KHz. A discussion of the release and maths is [here](https://quantasylum.com/blogs/news/qa350-gets-true-rms)
