Changelog

The original LMS8001 Companion Board launched in 2017 was hardware revision 2v1 and so this changelog starts with changes from that point.

Note

Details of internal-only versions which were never released are not included here.

3v2

There are very few board design differences since we tried to keep the original design as much as possible. Updates were mainly made due to obsolete components and a change in the operational band.

• IF frequency was changed from 1.2 GHz to 2 GHz;

• RF band optimisation was changed from 5-6 GHz to 6.5-7.5 GHz.

This resulted in matching components being changed to optimise the board response.

Note

For baluns (TC1-1-13M+ and NCR2-113+), the fields Old Value and New Value are the same as Old MPN and New MPN fields, respectively.

USB Connector

The USB connector was changed from Mini Type B to Type C.

Table 7. Replacement for J1 component.

Component designation	Old MPN	New MPN
J1	Hirose’s UX60A-MB-5ST	Amphenol’s 12402143E512A

TVS Protection

TVS protection component U2 was changed due to an obsolete component.

Table 8. Replacement for U2 component.

Component designation	Old MPN	New MPN
U2	STMicroelectronics’ USBULC6-2P6	ON Semiconductor’s NUP2202W1T2G

Miscellaneous

Some minor changes in passive components such as MPN for 0R resistors or changes in MPN for LED diodes were made. Since these replacements do not affect the functionality of the board they will not be listed here.
