Many Amlogic S905 TV boxes have been announced, and thanks to Videostrong, I’ve received my first Amlogic S905 device for review with their K1 Plus media player (aka KI Plus). Today, I’ll start by listing the specifications, before taking a few pictures of the device and its board. with the full review following up in a few days.

Videostrong K1 Plus Unboxing
I received the device by DHL in a retail package with the markings “KI Plus” and “Quad-core Android DVB” on the top, as well as specifications on the bottom.
The device looks exactly the same as Videostrong’a previous models, such as K1 with S805, and comes with an IR remote control with IR learning function, a 12V/1A power adapter, an HDMI cable, and a user’s manual in English.
There’s again mention of “Android DVB” simply because there are optional DVB-T/T2, ATSC, and ISDB-T tuners for the device according to the user’s manual. The company also plans to send me a DVB-S2 version in a few weeks.
A closer look at the TV box shows the four USB ports and micro SD slot on the side, and all other connectors on the rear panel: CVBS/ LR audio jack, Ethernet (RJ45), HDMI 2.0 output, optical S/PDIF and the power jack.
You could also watch the unboxing video below.
Videostrong K1 Plus Teardown
On the back of the case, we’ll notice the device can be wall-mounted, and I’ve marked the location of the two screws you need to loosen in order to open the case.
Once you have removed the screws, it’s relatively easy to pop up the top part of the case with a sharp and strong plastic tool.
Amlogic S905 processor is quite tiny, and is covered by a small heatsink. SKHynix H27UCG8T2ETR NAND flash provides 8GB storage, while two Nanya NT5CB256M16DP-EK DDR3 chips are used for the memory (1GB). GL852G USB 2.0 hub controller gives the board its 4 USB ports, and a module based on Realtek RTL8189ETV provides 802.11 b/g/n WiFi connectivity. Pulse H1102NL transform confirms I’ve received a model with Fast Ethernet.
The board name is K1_S905_REV2.0. Three connectors are soldered in the side of the board. The 26-pin black header is most likely for digital tuners, and the two other 3-pin and 4-pin headers have Tx & Rx markings on the back of the board, so one of them is likely to be used for the serial console.
The recovery / firmware update button (K1) can also be seen on the back of the board.
I’d like to thanks Videostrong for sending a sample. If you are interested in purchasing the board in quantities, you may want to contact the company via their Alibaba product page. K1 Plus, also named Ki Plus on some websites, is available on retail sites starting at just $42.99 shipped on GearBest, GeekBuying, eBay, Amazon US, Aliexpress and others.

I wonder if an ATSC tuner will make it to this one. Thanks for the peek in to this S905 box.
What’s the button to the left of the USB port?
That’s a TF card slot, better known as micro SD slot.
What does SW5 button do?
Ah OK… I think I misunderstood vickycq comment now.
SW5 is the power button. It’s controlled by the power LED/button on the top of the device.
If you watch the video, you can see I press it.
Oh, I see that. Thanks!
please to test very high biterate HEVC videos like 60 Mbps+ and to include KODI 16 beta 1 in the tests, I think it will be a very good device, looking forward for the DVB S2 version as well
If you could test KODI plus HEVC 10bit it would be great
The case design kinda reminds me of the wetek play / core. Very interested in checking one of these S905 boxes out myself hopefully the 912s wont be too far behind either.
HDCP 2.2 support? I don’t see Videostrong in HDCP 1.x or 2.x licensed adopter list.
the unboxing video needs VPN if I want to watch from mainland China..
That’s what they wrote on the package, but I don’t think they support it by default.
Most apps can’t be installed via Google Play Store with the message “your device isn’t compatible with this version”.
The only thing that I installed was DRM Info: no Widewine, no Playready support at all.
I’ve decided to postpone K1 Plus review until they provide a new firmware that fixes the Google Play issue.
I don’t know whether it’s an old news, but there is a linux kernel on amlogic web page that seems quite recent (arm-src-kernel-2015-11-04-9e845bea41.tar.gz) that has meson64_defconfig under arch/arm64/configs. I wonder whether it’s the config for S905…

clearer after seeing todays S905 VS S805
K1 PLUS $40( limited quantity, around 10 hours left):
Just got my K1 Plus S905 in the mail today, this is my first android TV, where should I go to update, new apps and the latest news about this kind of stuff?
Since K1 Plus does not have OTA firmware update install, you can try: http://www.cnx-software.com/2015/11/24/how-to-upgrade-firmware-on-amlogic-s905-tv-boxes/
You may already have that version of the firmware, or even more recent. So check before getting an update.
Manufacturers of K1 Plus did not setup a support form or anything like that, so your best bet would probably to check Freaktab forums.
Is this still the latest firmware for the KI Plus dvbs2 box?
Freaktab, got it, thanks.
currently running p20x-userdebug 5.1.1 LMY47V 20151123.183302.V1031 test-keys
I heard that 20151128 and 20151204 are the new ones, installed both and they dont change this Build number in the Settings screen. weird?
when we can expect the review, looking forward to it 🙂
I’m guessing sometimes in March.
sorry, not this one, I’m mistaken, I meant the combo version with DVB tuners http://www.cnx-software.com/2016/01/08/specs-unboxing-and-teardown-of-ki-plus-android-tv-box-with-dvb-t2s2-combo-tuner/
is there any python or C++ library for S905 gpio???
You could use sysfs to control the GPIOs.
Other options include https://github.com/hardkernel/wiringPi and https://github.com/hardkernel/WiringPi2-Python

How do you program the k1 plus to receive directv ??
just bought a K1 Plus and also have problems receiving direct tv.
Found some instructuions here but they didn’t work for me. 🙁
http://www.cnx-software.com/2016/02/22/how-to- configure-dvb-s2-and-dvb-t2-tuners-in-k1-plus-android- dtv-receiver/
I am able to get a signal strength of 80-90% but 0% quality despite choosing the correct country setting.
Are there other settings reqiuired?
Any advice would be appreciated.
Do you get a list of channels once the search is finished? I guess you set the right satellite?
finally i got this box
i’m using it with Samsung TV, the problem is with screen resolution,i changed it to be 1080/50p because of all Europe Channels use 50hz
original app DTV not so smooth in 1080/60p specially in HD and 4k,i think there is frames drop
the problem when i plug off box from mains , android return to 1080/60p , how can i solve this big problem
