 ## Summary
 
+The BaseBoard is a DPP Application platform based on the Colibri Arm System on Module (SoM) family from Toradex. It enables to run a full-fledged Linux distribution, direct integration/usage of all DPP Communication boards and integrates a multitude of sensors. It has been designed to facilitate low-power operating modes.

+
+### Specifications
+
+  * [Colibri Arm Family](https://www.toradex.com/computer-on-modules/colibri-arm-family) SODIMM sized SoM from Toradex (e.g. iMX6/7/8, Tegra 2/3, pin compatible) as processing unit
+  * DPP header to connect to a DPP Communication board (DPP COM board can wake-up
+    Colibri SoM, additional TinyNode184 header for backward compatibility)
+  * [SARA-U270](https://www.u-blox.com/en/product/sara-u2-series) cellular module (SARA-U270 can wake-up Colibri SoM)
+  * [RV-8803-C7](https://www.microcrystal.com/en/products/real-time-clock-rtc/rv-8803-c7/) low-power RTC (RV-8803-C7 can wake-up Colibri SoM)
+  * [ZED-F9P](https://www.u-blox.com/en/product/zed-f9p-module) GNSS receiver module
+  * [SHT31](https://www.sensirion.com/en/environmental-sensors/humidity-sensors/digital-humidity-sensors-for-various-applications/) Temperature/Humidity sensor
+  * [LSM303C](https://www.st.com/en/mems-and-sensors/lsm303c.html) Accelerometer/Magnetometer
+  * [SCL3300](https://www.murata.com/en-sg/products/sensor/inclinometer/scl3300) Inclinometer
+  * Power switchable interfaces (Ethernet with passive PoE, Host/Client USB, 3x power
+    connectors) capable of delivering up to 7.5A
+  * Break-out header (e.g. I2C, SPI, UART, GPIOs, PPS, ...)
+  * Wide input power range (4.5V - 36V)
+  * Industrial temperature grade (-40ºC to +85ºC)
+  * Fits into a "small" weatherproof [Bopla](https://www.bopla.de/en/enclosure-technology/product/euromas-aluminium-euromas-f05/euromas-aluminium-enclosures/a-118.html) enclosure (160x100x80mm, IP66)
