The fact is, however, that the Sparky SBC worked well right from the start. I had neither, and I anticipated a tedious time connecting a non-HDMI-compliant TV/ monitor with Sparky. The Sparky SBC is designed to use HDMI, requiring either an expensive HDMI monitor or a television with an HDMI port. Ironically, the Raspberry Pi, with its composite video, is also a better fit for my situation. Because the “Sparky Quick Start Guide” provides easy-to-follow setup instructions, users can run their first test pretty quickly.īefore trying Sparky out, I was initially worried that the community support for Sparky wouldn't be as rich as that of the Raspberry Pi, leaving me minimal resources outside of the owner’s manual I anticipated that getting the device working might require substantial effort and that I would have no one to turn to. Gigabit Ethernet (GbE) - 2x Gigabit Ethernet ports via USB 3.0Īllo usually ships all requisite components (with the optional 5-V/3-A micro USB power adapter) bundled in a single, cohesive deployment package.Wireless - Wi-Fi, Bluetooth, and ZigBee.eMMC - 8GB, 16GB, 32GB, or 64GB eMMC flash. ![]() LCD - 7- or 8-inch, 1024 x 600 touchscreen with high-end glass frame.Audio amplifiers - 138-mW Direct Path stereo headphone amplifier with 102-dB signal-to-noise ratio, supporting 50-W output, and a stereo Hi-Fi amplifier using a 384-KHz/32-bit Texas Instruments DAC with integrated DSP running TI's PurePath software.In addition, Allo is offering a number of shields specifically for Sparky, including By using the GPIO Header/RPi card connector, designers can leverage many of the Raspberry Pi HAT-compatible shields available on the market. GSM Gateways are but a single example of the wide-ranging applications that the Sparky SBC can power. ![]() The design employs the AirPrime GSM module from Sierra Wireless and acts as a standalone, fanless, and easy-to-install 4-Port GSM Gateway to bridge the gap between traditional telephone networks and VoIP networks. Nair pointed out, for example, that Allo designed and launched a 100% open-source GSM Gateway using the Sparky SBC as the base board. There are also some LEDs and buttons, optional NAND or eMMC expansion, a 40-pin GPIO connector that is Raspberry Pi-compatible, and a special 50-pin telecom connector.Īccording to Gireesh Nair, Allo's pre-sales and service delivery manager, Sparky's 50-pin special telecom connector is there to support VoIP applications. The Sparky SBC also offers most other popular interfaces, including:
