Up2stream Mini & Pro v3 Audio Boards Add Bluetooth 5.0, USB Sound Card Mode and More

Rakoit launched Up2stream WiFi audio board in 2018, followed by Up2stream Pro board in 2019 with additional Bluetooth, Ethernet, and USB interfaces. Those boards are designed to bring network connectivity to speakers for audio streaming. The company has now launched updates with the launch of Up2stream Mini v3 and Up2stream Pro v3 connected audio boards. Both Up2Stream Mini v3 and Pro v3 have gotten similar updates with the ability to use the board as a micro USB sound card so you can directly plug it into a PC to make it work as a USB DAC. The boards also added SPDIF out, an ADC KEY input for external buttons, two I/O for extensions such as volume knobs. Up2stream Mini v3 now includes both WiFi and Bluetooth 5.0 connectivity. Shared key features and specifications of the boards are as follows:  Audio Output – 3.5mm audio jack and header (shared), I2S & S/PDIF (44.1 kHz) headers Input (Pro v3 only)–  3.5mm audio […]

Amlogic A111, A112 & A113 Processors are Designed for Audio Applications, Smart Speakers

Amlogic processors are mostly found in TVs and TV boxes, but the company is now apparently entering a new market with A111, A112, and A113 audio processors. I was first made aware of those new processors through Buildroot OpenLinux Release Notes V20170831.pdf document posted on their Open Linux website, where two boards with Amlogic A113D and A113X are shown. First, S400 board with the following key features/specifications: SoC – Amlogic A113D CPU System Memory – 1GB DDR3 Storage – 512MB SLC NAND flash Display I/F – MIPI interface Connectivity – Gigabit Ethernet SDIO WiFi/BT (AP6356S) Audio SPDIF_IN/SPDIF_OUT LINE_IN/LINE_OUT 2x Audio headers (MIC_Connector & SPK_Connector) USB – 1x USB 2.0 OTG Expansion – 2x PCIe ports Misc – 6x ADC Keys, IR_IN/IR_OUT, UART Interface (RS232) The second S420 board is based on A113X SoC, and comes with less features (no display, no Ethernet, no PCIe…), less memory: SoC – Amlogic A113X CPU System Memory – 512 MB DDR3 Storage – 512MB […]

VoltaStream ZERO NXP i.MX6ULL Linux Audio Board Follows Raspberry Pi Zero Form Factor

Back in 2013. Philip came with the idea of designing a development board for audio application, and after various experiments with off-the shelf Raspberry Pi boards and audio DACs,  he founded PolyVection company, and started designing the board. Forwarding to today, he has completed his work and introduced VoltaStream ZERO to the world, a board based on NXP i.MX6ULL processor with 512MB or 1GB RAM, and a choice of Texas Instruments DAC. It also follows Raspberry Pi Zero form factor, like the upcoming Banana Pi BPI-M2 Zero board. VoltaStream ZERO specifications: SoC – NXP i.MX6ULL ARM Cortex-A7 processor @ 996 MHz System Memory – 512 MB or 1 GB DDR3 Storage – micro SD card slot Audio 1x I2S for integrated DAC, 1x I2S for GPIO access, 1x S/PDIF header / TOSLINK jack Analog DAC – Texas Instruments PCM5121 (106 dB) or PCM5142 (112 dB) USB – 1x micro USB slave port (USB gadget mode supported), 1x USB type A […]

Review of Allo Vana Player Linux HiFi Audio System with Max2Play, SqueezeBox and Kodi

Last month I showcased what I called “Allo Sparky Audio Kit” with a DAC board (Piano), an amplifier board (Volt), and usually hard to find  reclocker and capacitance multiplier boards (Kali & CM), all connected to Allo Sparky ARM Linux development board powered by Actions Semi S500 quad core Cortex A9 processor, and running Ubuntu 12.04. In the first post, I just described the boards, and showed how to assemble the kit, but now that I have received the user’s manual, it turns out the kit is actually called “Vana Player” and the provided Ubuntu firmware image runs Max2Play Browser based system that’s also available for Raspberry Pi and ODROID boards. Before starting the kit, you’ll need to connect speakers to Piano DAC board and/or Kali board, as well as a 19.5V power source such as a laptop power supply to connect to the CM board. I connected some USB powered speakers to the headphone jack of Piano board, and […]

How-to Setup a DLNA/UPnP Server in Linux for Smoother Video Streaming with Kodi and Other Media Players

I’m normally playing videos from a SAMBA share installed in a Ubuntu PC to play files from Kodi in Android TV box reviews, but sometimes when I use 10/100 Ethernet, or worse WiFi local “streaming” may not be as smooth as possible. SAMBA is convenient because of access control and read write operations, but if you want to get a bit more performance, you may switch to NFS instead, or like I’ve going to show you here to a DLNA / UPnP server to stream videos locally from Kodi 16.1. There are several options, but MiniDLNA is lightweight compared to MediaTomb, so it will also run on lower end hardware like cheap ARM Linux development boards like Raspberry Pi, Orange Pi, or NanoPi NEO without taking too many resources. Installation is very easy in Debian / Ubuntu distributions, and I supposed this should also work with Windows Subsystem for Linux in Windows 10: MiniDLNA can be configured with the same […]

Mini Review of Doogee Smart Cube P1 Android Projector

Doogee Smart Cube P1, or just Doogee P1, is an Android projector powered by a quad core Amlogic processor. I’ve already taken some pictures of the device, and gave it a quick try, so today, I’ll write a little more about my experience using it in standalone mode with an air mouse, as well as with an Android phone using both Miracast and DLNA. The device also supports Airplay, but I don’t think I have any compatible device, so I have not tried this mode. Doogee P1 in Standalone Mode with an Air mouse (or other wireless/USB input device) After connecting MINIX NEO A2 lite air mouse’s RF dongle to the only USB port on the device, I pressed the power button for 5 seconds to start it up, and boot is pretty fast in around 30 seconds. You’ll need to adjust the focus with the wheel button on the side. It will start with the stock Android launcher, showing […]
