This is the USB interface Module for the Overkill Solar BMS (among others)

Desktop software is free to download.

This module is a USB to TTL UART adapter.
It will make a new COM port available on your PC,
which can be used with the provided software, or custom applications to monitor and adjust the parameters of the BMS.

FYI for experimenters: The BMS communicates with a 5v TTL UART at 9600 baud. It is directly compatible with Arduinos, etc.
The protocol is similar to MODBUS. requests and responses are in HEX. Protocol datasheet is available.

    Using the driver from the Victron community, I was able to connect this to a Venus GX. Reports the BMS values accurately to the Venus.
