An ESP32-S3 device from LILYGO with a CC1101 named in its title and an external antenna, sold as open-source hardware whose five bullets contain links to documentation rather than specifications.
The bottom line A listing that points elsewhere for everything. For a device at this price, a buyer has to evaluate it on its repository and wiki, because the page itself offers nothing to compare.
The T-Embed CC1101 Plus listing, bullet by bullet
Five bullets: an external antenna on this version; a GitHub link; a wiki link; an offer of product support; and a note that the hardware is open source, the firmware updated by the community, and all documentation kept on GitHub and the wiki instead of in print.
Specifications by link
Every figure a buyer might compare lives off the page. The title names an ESP32-S3 and a CC1101; the bullets give two addresses. That is honest about where the information is, and it leaves this review with a row of absences.
Open source as the argument on the LILYGO page
Community firmware and online documentation are real advantages for a platform that changes quickly. They are also a reason to read the repository first, because the device’s capabilities depend on its current state.
Price against information
At the top of this family’s price range, the T-Embed has the thinnest listing of the six. The value is in the ecosystem the links point to, and a reader has to follow them to judge it.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 82 € to 85 €.
It is sold in the American and British Amazon stores as well, in their own currency, which the euro figures above leave out on purpose.

Where it earns its place, and where it falls short
Strengths
Open-source hardware with community-maintained firmware, as the fifth bullet says
Documentation kept current on GitHub and the maker’s wiki rather than in a printed manual
An external antenna in this version
Compromises
No specifications in any bullet
The CC1101 is named in the title without saying what it does
The dearest of the six boards here, with the least information on the page

Questions makers ask before buying
Where is the LILYGO T-Embed CC1101 Plus documented?
The second and third bullets link to a GitHub repository and the LILYGO wiki, and the fifth says all current documentation is collected there because printed manuals date quickly.
What antenna does the T-Embed CC1101 Plus use?
The first bullet says this version uses an external antenna.
