Dragonboard 410c is a powerful piece of hardware with support for Wi-Fi, Bluetooth and even GPS with on-board antennas.

 It is a 64-bit capable Snapdragon 400 series processor with some neat specs: 

  • CPU: Quad-core ARM® Cortex® A53 at up to 1.2 GHz per core with both 32-bit and 64-bit support.

  • Memory/storages: 1GB LPDDR3 533MHz / 8GB eMMC 4.5 / SD 3.0 (UHS-I)

  • Connectivity and Location

    • Wi-Fi 802.11 b/g/n 2.4GHz, integrated digital core

    • Bluetooth 4.1, integrated digital core

    • Qualcomm® IZat™ location technology Gen8C

    • On-board Wi-Fi, BT and GPS antenna

  • I/O Interfaces: HDMI Full-size Type A connector, one micro USB (device mode only), two USB 2.0 (host mode only), micro SD card slot

Note: Micro USB (device mode) and USB 2.0 (host mode) are mutually exclusive and cannot be operated at the same time. Keep this in mind, especially while debugging.

  • Expansion:

    • One 40-pin low speed expansion connector: UART, SPI, I2S, I2C x2, GPIO x12, DC power

    • One 60-pin high speed expansion connector: 4L MIPI-DSI, USB, I2C x2, 2L+4L MIPI-CSI

    • Footprint for one optional 16-pin analog expansion connector for stereo headset/line-out, speaker and analog line-in.

The board has more to offer (camera support, graphics, video). But for now I will skip them as they are not relevant for our work.

It would have been nice to have a RS232 to help debug (but would have made the board bigger and bulky). The UART on the expansion connector is 1.8V and needs an expensive UART to USB converter.

Micro USB and USB 2.0 are mutually exclusive. But for our development, it is fine. Once we are done with initial setup, we will not need both. We will use the micro USB for fastboot, and to load the image. Once done we will switch to USB 2.0 (keyboard/mouse) to setup Wi-Fi.

You can get it from Arrow for $75. It comes loaded with Android and can support Linux (Linaro - supported by Qualcomm Landing Team), and Windows 10 IoT core. It needs a minimum of 6.5V power supply. The power supply provided with the board supplies 12V.

Spend sometime staring at the board. Make note of the switches (and their positions), LEDs, vol buttons, SD card slot etc.
