![]() The basic design includes FPGA based FIFO board.You will hear sounds, words, instruments that were drowned before in a sea of digital mud.ĭo you enjoy a better wine/microbrewery beer, or anything will do? Do you have some medium/good speakers or you are using the cheapest PC speakers? Do you love music or just want to hear some beats? The stage will sound bigger, more tri-dimensional. The million dollar question (actually $69): how does it sound? We highly recommend our Piano 2.1 - they were designed to work perfectly toghether! Kali will not work if your DAC is a master. Meanwhile, it will clock the file using the correct crystal (there are 2), fixing the problems outlined in the beginning. Using the NDKs it will reclock the buffered data OUTSIDE the fpga (since fpgas introduce about 200ps of jitter) and provide a MCLK/BCLK that is direct from crystal, providing a jitter-free (almost) to your DAC. Second, the FPGA will read the incoming stream, will buffer the DATA 0.7s while discarding the incoming clocks. Some SBCs (like RPIs) can output only 48Khz, so imagine the degradation of the sound that was recorded at a different frequency.įirst, it has a very low jitter NDK crystal feed by LDOs in series for ultra quiet power supply. Simply put: a better crystal means a better sound! Most SBCs use a very cheap crystal with lots of jitter in order to save costs.įurthermore, there are 2 kinds of frequencies for digital files: 44.1Khz (wave files) and 48khz (streamed music). The accuracy of this crystal is very important in how well the DAC will transform the digital signal into analog sounds. For WiFi connectivity, we suggest using our WiFi dongle (driver has been fully tested).ĪRM Cortex A9 Quad Core Processor 1.Every SBC has a crystal that it used to send digital signals to your DACs.Power: The board uses up to 10W of power and can be powered from the USB connector, or a separate 3.7V / 3500mAh battery power supply.Connector: 40 pin connector (Raspberry Pi compatible) to enhance your “real world” projects or connect the shields.External Storage: Micro SD up to 32GB and eMMC slot up to 64GB for storing information and loading operating systems.Ethernet: On board Single Ethernet port 10/100Mbps.Expansion Shields ready (Piano DAC, Piano DAC 2.1, BOSS, Volt, Kali, Cheapo, GIGA, LCD, Camera, eMMC, etc.).CPU: ARM Cortex A9 Quad Core Processor at 1.1GHz.With over a decade of embedding experience, our team is constantly helping application developers to port their new and exciting software to our Sparky SBC. we also offer the following add-on boards, like Piano Hi-Fi DAC, Volt AMP, Cheapo, GIGA dual Ethernet, Telecom Analog Shield and GSM Shield. Sparky also provides the flexibility to use any of the Raspberry PI add-on boards currently available. Some of the applications are Internet Of Things (IoT), Tablet, Smart TV, Net Book, Game Console, POS machine etc. It is the best choice for developing customized products as it provides an open, strong and friendly system development platform. The Sparky SBC currently supports Linux and Android operating system. Sparky is a highly integrated SBC, based on ARM application processor. The Sparky SBC has all the functionality of a basic computer. A true open hardware, community-supported embedded computer for developers and hobbyists. ![]() Sparky Single Board Computer (SBC) is a credit card-sized board that can be used as a standalone computer, in electronics projects, games, and also in many other applications. ![]()
