VoltaStream AMP1 Linux Audio Board Includes a Stereo Audio Amplifier, Adds WiFi and Bluetooth

Last summer I wrote about VoltaStream ZERO an audio board powered by NXP i.MX6ULL processor, with up to 1GB RAM, a Texas Instruments DAC, and leveraging Raspberry Pi Zero form factor. The board runs a custom Linux distribution called PolyOS built with the Yocto Project, and including shairport-sync, librespot, SqueezeLite, a DLNA renderer, and more. Polyvection, the company behind the project is now back with VoltaStream AMP1 audio development board, with half the board very similar to VoltStream ZERO, and the other half featuring an audio amplifier, and a wireless module for WiFi and Bluetooth. VoltaStream AMP1 board specifications: SoC – NXP i.MX6ULL ARM Cortex-A7 processor @ 996 MHz System Memory – 512 MB DDR3 Storage – micro SD card slot Audio 1x I2S for integrated DAC and AMP, 1x I2S for GPIO access, 1x TOSLINK-IN jack Analog DAC – Texas Instruments PCM1862 (SNR 103 dB) Amplifier – ISSI IS31AP2121 / class-D / SNR 104 dB; 2x 35 Watt (2x …

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 …
