ATS Mini V4 Known Genuine Sellers (Counterfeit Warning)

AMNVOLT (the manufacturer) has publicly warned about counterfeit V4 units — specifically sellers using inferior ESP32 modules, and units with metal casings housing older V1 board revisions being sold as "V4."

Red Flags

Metal casing without "V4" and "AMNVOLT" printed on it (the official site notes at least one legitimate reseller sells a neutral-branded metal case version — check current listings for which specific listings this applies to, since this is an evolving situation)
Prices significantly below the typical $30-50 range for genuine units
No brand markings on front/back panels
Missing the built-in headphone amplifier / Hi-Z circuit that's supposed to be standard on genuine V4

How to Verify

Check the official AMNVOLT website's listed authorized reseller links before buying from an unlisted store
Review product listing photos/comments from other buyers for the specific listing you're considering
Genuine V4 should show non-zero PSRAM in Settings > About once you have current community firmware flashed — a strong indicator of genuine ESP32-S3 hardware matching the expected spec

This is a real, actively-discussed issue in the ATS Mini community (referenced directly on the manufacturer's own FAQ page) — worth 10 minutes of research before ordering from an unfamiliar seller.
