+Zolertia RE-Mote platform
+============================================
+
+The RE-Mote platform (Revision B) is a IoT Hardware development platform based
+on TI's CC2538 system on chip (SoC), featuring an ARM Cortex-M3 with 512KB
+flash, 32Kb RAM, double RF interface (Sub-1GHz CC1200 RF transceiver), and the
+following goodies:
+
+* ISM 2.4-GHz IEEE 802.15.4 & Zigbee compliant.
+* ISM 868-, 915-, 920-, 950-MHz ISM/SRD Band.
+* AES-128/256, SHA2 Hardware Encryption Engine.
+* ECC-128/256, RSA Hardware Acceleration Engine for Secure Key Exchange.
+* Power consumption down to 150nA using our shutdown mode.
+* Flashing over BSL without requiring to press any button to enter bootloader mode.
+* Built-in battery charger (500mA), Energy Harvesting and Solar Panels to be connected to standards LiPo batteries.
+* Power input with wide range 3.7-16VDC.
+
+
+Changes from Revision A
+=========================
+
+The list of changes are summarized in the [Wiki](https://github.com/Zolertia/Resources/wiki/RE-Mote:-Enhancements-from-Rev.A-to-Rev.B)
+
+Port Features
+=============
+In terms of hardware support, the following drivers have been implemented:
+
+  * CC2538 System-on-Chip:
+    * UART
+    * Random number generator
+    * Low Power Modes
+    * General-Purpose Timers
+    * I2C/SPI library
+    * LEDs
+    * Buttons
+    * RF switch to programatically drive either 2.4GHz or sub-1GHz to a single RP-SMA
+    * RF 2.4GHz built-in in CC2538
+
+And under work or pending at cc2538 base cpu:
+
+    * Built-in core temperature and battery sensor.
+    * CC1200 sub-1GHz radio interface.
+    * Micro-SD external storage.
+    * ADC
+    * USB (in CDC-ACM).
+    * uDMA Controller.
+
+Requirements
+============
+
+ * Toolchain to compile RIOT for the CC2538
+ * Drivers to enable your host to communicate with the platform
+ * Built-in BSL programming over USB using cc2538-bsl (included)
+
+
+Install a Toolchain
+-------------------
+The toolchain used to build is arm-gcc, to check if it is currently installed run:
+
+    $ arm-none-eabi-gcc -v
+    Using built-in specs.
+    Target: arm-none-eabi
+    Configured with: /scratch/julian/lite-respin/eabi/src/gcc-4.3/configure
+    ...
+    (skip)
+    ...
+    Thread model: single
+    gcc version 4.3.2 (Sourcery G++ Lite 2008q3-66)
+
+Else install from <https://launchpad.net/gcc-arm-embedded>
+
+
+Drivers
+-------
+The RE-Mote features a CP2104 serial-to-USB module, the driver is commonly found in most OS, but if required it can be downloaded
+from <https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx>
+
+
+### For the CC2538EM (USB CDC-ACM)
+The RE-Mote has built-in support for USB 2.0 USB, Vendor and Product IDs are the following:
+
+  * VID 0x0451
+  * PID 0x16C8
+
+On Linux and OS X this is straightforward, on windows you need to install the following driver:
+
+<https://github.com/alignan/lufa/blob/remote-zongle/LUFA/CodeTemplates/WindowsINF/LUFA%20CDC-ACM.inf>
+
+And replace the IDs accordingly.
+
+### Device Enumerations
+For the UART, serial line settings are 115200 8N1, no flow control.
+
+Once all drivers have been installed correctly:
+
+On windows, devices will appear as a virtual `COM` port.
+
+On Linux, devices will appear under `/dev/`.
+
+On OS X, `/dev/tty.SLAB_USBtoUARTx`.
+
+On Linux:
+
+* RE-Mote over CP2104: `ttyUSB0`
+* RE-Mote over USB driver (in CDC-ACM): `ttyACMn` (n=0, 1, ....)
