Amlogic S905X4 Android TV & RDK developer kit ships with ATSC, DVB, or ISDB tuners

We were expecting Amlogic S905X4 TV boxes with products like Ugoos X4 or Mecool KM6 by the end of last month, but due to supply issues manufacturing has been delayed.

However, if you’d need a device to get started with your own project as soon as possible, for example, to work on AV1 hardware decoding implementation, SEI Robotics has launched an Amlogic S905X4 developer kit for Android TV & RDK development under their DroidLogic brand. The devkit looks like a standard TV box, and the company also provides a choice of tuners with DVB-S2, DVB-T2/C, DVB-S2+DVB-T2/C Combo, ISTB-T, or ATSC-T.

SEI Robotics does not provide software development kits, but the company told CNX Software the RDK SDK can be downloaded from the official website, while Android TV code can be obtained on Amlogic git if a TADA agreement (TV Application Distribution Agreement) has been signed with Google. AOSP is another option. For reference, SEI Robotics worked with Google on ADT-2 developer kit.

The company confirmed DroidLogic Amlogic S905X4 developer kit is available now and ready to ship. It’s clearly not a consumer product, as it sells for $199 whether you add a tuner or not.
