The Dragonboard 410C from Arrow has been certified for Windows 10 IoT-Core and comes with Android installed. This blog takes a close look at the board’s features. . Subsequent blogs will look at using the board in Android and IoT-Core modes.

The board is a feature rich, relative high performance single board ARM computer. It has on-board WiFi, Bluetooth and GPS including on-board aerials. With 1 Gig of RAM and 8 of Flash as well as Micro SD storage there is a significant capability for developing a substantive consumer or IoT device. Its media capabilities far surpasses many other similar purpose SBCs. It does though lack implementation of some I/O capabilities such as headset and UART although these only require the relevant connectors and some level shifting; the signals are present on the board. As supplied, the board has the Android operating system installed which the next blog in this series will cover. Windows 10 IoT-Core is certified to run on the board. A later blog in this series will cover that.
The board conforms to 96Boards format which means standardised daughter boards can be used with it for implementing I/O.

Profile
96 Boards
Low speed Expansion
40-pin connector: UART, SPI, I2S, I2C x2, GPIO x12, DC power
Audio Expansion
16-pin analog for stereo headset/line-out, speaker and analog line-in.Note: Expansion connector not fitted
High Speed Expansion
60-pin high speed expansion connector: 4L MIPI-DSI, USB, I2C x2, 2L+4L MIPI-CSI
The recommended power supply is 12V with a minimum of 1A. If USB peripherals require significant power, then 1.5-2.5A is recommended. A powered USB hub could alleviate the higher current need, whilst providing more USB ports.
Note: Digital signal are generally 1.8V and will require level shifting when interfaced to many external components.
In the picture above, from bottom left of the board, the right most push button is the power button. Pressing this will put the device into suspend. It can also be used to resume. The other two push buttons’ main function is volume up and down or zoom in/out depending upon the app context.
There are 4 LEDS located in between the two USB Host sockets. The are “USER LEDS 1 2 3 4”.
