Great Buy
great buy. came with all the stuff, except one missing 2x3 header. buuut that's fine. the chips are legitimate, and it matches uncannily with the product images. works totally fine.

Does NOT Come With Teensy
This is ONLY the Ethernet kit and PSRAM chips. NO TEENSY IS INCLUDED. The product is priced as if it includes a Teensy but it does not. The listing shows all the Teensy specs in the product specifications and lists it right above the included items but it is not a part of the deal. Nowhere do they specify that the Teensy is not included which is highly deceptive. This review is not a reflection of the Teensy 4.1 dev board itself but this specific scam listing.

Extremely Misleading Product Listing
Completely agree with the other one star review. This is a deeply misleading product listing. It does not include the board. Even the packaging when the product arrives includes an insert making it seem like there's a board, but it does not exist.

DO NOT BUY!!
I wish I could give a zero star. The shipment did not contain THE BOARD!!! Only the ethernet kit was shipped. Very, very unhappy.
