While we’ve already covered many Rockchip RK3328 TV boxes and development boards, if you want a TV stick form factor the choice becomes much more limited.
So far I was only aware of Rikomagic RKM V3 , but today I’ve come across ULEWELL Z28 MINI, selling for about $40 on Aliexpress with 2GB RAM, 16 GB storage, HDMI 2.0a, and a USB 3.0 port.

The specifications also list a micro SD card (“TF card”), but it’s not apparent on any of the photos. The stick runs Android 7.1 OS (not Android TV).
The device ships with a power supply + USB cable, a HDMI cable/adapter, a lanyard, and a user manual.
Beside Aliexpress, the TV stick can also be found on GeekBuying, Banggood (use 8118d3 coupon for discount), Tomtop, and other sites.If you prefer something with dual band WiFi, and an actual micro SD card, QINTAIX R33 is another option for $62.39 shipped.
