-  abstract: >
-    As the Internet of Things (IoT) emerges, compact operating systems (OSs) are
-    required on low-end devices to ease development and portability of IoT
-    applications. RIOT is a prominent free and open source OS in this space. In
-    this paper, we provide the first comprehensive overview of RIOT. We cover
-    the key components of interest to potential developers and users: the
-    kernel, hardware abstraction, and software modularity, both conceptually and
-    in practice for various example configurations. We explain operational
-    aspects like system boot-up, timers, power management, and the use of
-    networking. Finally, the relevant APIs as exposed by the OS are discussed
-    along with the larger ecosystem around RIOT, including development and open
-    source community aspects.

-@ingroup     boards
-@brief       Support for the Alientek Pandora board
-
-## Overview
-
-The Alientek Pandora is a development board manufactured jointly by Alientek and RT-Thread company.
-It is based on STM32L475VET6 and have on-board LCD, SD card and WiFi access.
-Users may connect to its on board ST-Link 2.1 compatible debugger to flash or debug.
-
-Documents of this board are available on its [Alientek official website](http://www.alientek.com/productinfo/716137.html).
-It may require a translation software to read it in English.
-Additional resources may be found on [RT-Thread bsp support page](https://gitee.com/rtthread/rt-thread/tree/master/bsp/stm32/stm32l475-atk-pandora).
-
-### Flashing the board
-
-To flash the board, use the on board ST-Link programmer/debugger.
-Input the following command:
-
-    make BOARD=alientek-pandora -C examples/hello-world flash
-
-The NRST pin is connected to the on board debugger, so users do not need to reset manually
-every time it requires to flash.
-
-If the operating system raised a fault, users may manually reset the chip by pressing the reset button.
-This button has a black color and is located between the four keys and the LED light.
-
-### STDIO
-
-STDIO is connected to pins PA9 (TX) and PA10 (RX).
-Before you begin, check that the both the jumper caps marked as 'USART1' is connected.
-
-Use the `term` target to open a terminal:
-
-    make BOARD=alientek-pandora -C examples/hello-world term
-
-An on-board ST-Link compatible debugger is used to transport serial STDIO message.

-## Flashing the Device
-
-The ATxmega-A1 Xplained needs an external programmer like atmelice.
-
-In order to flash the ATxmega128A1, simple run:
-
-    make BOARD=atxmega-a1-xplained flash
-
-## Serial Terminal
-
-The CDC-ACM will enumerate a /dev/ttyACM device. The STDIO at CDC-ACM shares
-with J4 pins 2/3.
-
-    make BOARD=atxmega-a1-xplained term
