Allo SPARKY Board Supports Raspberry Pi HATs for Multimedia, IoT and VoIP Applications

Allo is a company based in Bangalore, India specializing in VoIP hardware solutions, but they’ve recently developed a single board board powered by Actions Semi S500 quad core processor that supports various Raspberry Pi HATs and can be used for multimedia, IoT, and Telecom application such as Asterix or Freeswitch PBX.

The company has also developed several HAT compliant add-ons board for the board that can also be used on the latest Raspberry Pi models:

  • TI DAC – Audio board with PCM5122 DAC, TPA3116D2 amplifier, stereo RCA connectors, and a 3.5mm stereo jack
  • Amplifier board – Features hardware to connect left and right speakers, and signals to control volume. 24V DC input
  • PMU DAC & SPDIF connector – Optical S/PDIF, coaxial S/PDIF, TPA6133A2 stereo headphone amplifier that output to RCA, 3.5mm jack, or 2x50W speakers (hardware options)
  • Analog Board (Pictures above) – With for RJ11 ports configurable as FXO or FXS
  • Session Border Controller – Transparent Firewall with SIP Deep Packet Engine supporting up to 50 simultaneous calls. Based on MIPS processor couples with 64MB RAM, 16MB flash.
  • WiFi+Bluetooth+Zigbee – Based on F23BUUM13-W2 module (RTL8723BU) for Wifi and BT, and TI CC2530F256 for Zigbee with three external antennas.
  • USB to Ethernet – USB 3.0 to dual Gigabit Ethernet ports (RJ45) using Ax88179 controller.
  • I/O board – I2C I/O expander (18GPIOs), 40-pin ZIF socket, prototyping area etc..

There are also some other add-on boards that are not HAT compatible such as the eMMC modules which are similar to what ODROID boards are using, a 5MP camera module with autofocus, and a 7″ LCD display (1024×600) with a touchpad.

Allo SPARKY single board computer will become available for less than $40 in two to three months but I could already find it on a website (in German) for 47.60 Euros including VAT. Eventually, more information about SPARK and add-on boards should be found on Allo products page, but in the meantime, you can check out Allo SPARKY brochure with an overview of the board and HAT compatible shields.
