Datamax DM145S Hybrid TV Box with Digital Tuners is Powered by Amlogic S905D Processor

There are already several Amlogic Android TV boxes with dual tuner on the market, but so far you could not use both tuner at the same time, for example using one to watch live TV, and another to record TV [Update: WeTek Play 1st generation based on Amlogic AML87426-MX can do that]. Amlogic S905D is supposed to change that, and Datamax DM145S is the first device I’ve seen featuring the new processor.

datamax-dm14s5Datamax DM145S specifications:

  • SoC – Amlogic S905D Quad Core Cortex A53 @ up to 1.5 GHz with ARM Mali-450MP GPU
  • System Memory – 1GB RAM
  • Storage – 8 GB eMMC flash + micro SD slot
  • Video Output – HDMI 2.0a + AV
  • Audio Output – HDMI, AV and optical S/PDIF
  • Connectivity – 10/100M Ethernet, 802.11b/g/n Wifi, optional Bluetooth 4.0
  • USB – 3x USB 2.0 host ports
  • Tuner – Combination of DVB-C/T2, DVB-S2, ATSC or ISDB-T
  • Power Supply – 5V/2A
  • Dimensions – 115 x 115 x 28 mm
  • Weight – 200g

The device runs Android 6.0

amlogic-s905d-tv-boxI could not find the box for sale anywhere yet, but DM145S is listed on the company’s hybrid TV boxes page.

USB – 3x USB 3.0 host ports, really?
If so, it’d we awesome. Using 1 port for USB-Gbit adapter and rest 2 with some powered hub for 4 HDDs. With Armbian support (if we get it) that would be a good NAS then 🙂

Quoting the product page: ‘USB – High Speed USB 2.0 x3’. If S905D is designed like the other S905 (2 x USB 2.0) then most probably all 3 USB jacks are connected through an internal USB hub and have to share bandwidth. So from a ‘NAS perspective’ this is almost as crappy as any Raspberry Pi (lacking I/O and network bandwidth)

things might be much more complicated with S905D and S912
according to the kernel dev trying to mainline these SoCs, they feature an usb3 controller but usb2 phys…

Interesting read, thanks! But to be honest: it just confirms that this device will never be a good NAS since ‘built-in USB2 hub’ involved (if the hub would be USB3 capable then there wouldn’t be a bottleneck)

Somewhat ironic that people want to (mis)use TV boxes like this as NAS, development boards like OPi PC 2 as TV boxes while at the same time for this use case the latter would be more suitable (GbE and 4 independent USB 2.0 ports). But this might’ve been caused by a copy&paste error (3 x USB 3.0 vs. USB 2.0 as written on the product page).

My guess is the paltry 1GB RAM will lead to some disappointing performance. Specially when using both tuners.

A good looking box, but why go to all of this effort and not stick 2GB in there?

I have seen videos of Americans happy with Android boxes with tuners but UK and Europe users mostly complain of buggy software and bad performance. As R. D. says once you take the memory for screen resolution and software use out of the available 1 GB what is left for the user.

I am waiting for the price.
But with 1GB ram I will not buy it.
