Disassembly

There are four screws on the bottom, one of them is captive and does not come out. The red (or grey in the newer revisions) plastic is held on two points top and bottom each. It can be taken off with the help of a flathead screwdriver and pops off easily.

Usage

To receive data from the UT804 via USB the driver and the USB VID/PID of the WCH CH9325 needs to be specified like this:

sigrok-cli -d uni-t-ut804:conn=1a86.e008 --continuous
