+# Hardware layout #
+
+The [STMicroelectronics 
+32F769IDISCOVERY](https://www.st.com/en/evaluation-tools/32f769idiscovery.html) 
+is a board which is ideal for the Tardis project, as it offers plenty of 
+connectivity options and does not require soldering, making it an 
+excellent target to develop on for blind people. Here is the hardware 
+layout of this board. To follow along properly, please make sure the 
+board is on a flat surface, with the ethernet connector facing toward 
+you, and the LCD facing up.
+
+## Front edge ##
+
+* Ethernet connector.
+* 5v external power source connector (see below).
+
+## Left edge ##
+
+* ST-Link programmer micro USB connector.
+* USB OTG connector.
+
+## Back edge ##
+* 2x RCA connectors:
+	* RCA RX.
+	* RCA TX.
+
+## Right edge ##
+
+* 3.5mm jack line out connector.
+* 3.5mm jack line in connector.
+* Micro SD card slot.
+
+## Top side ##
+
+* 2x tactile buttons.
+	* Reset button near the ethernet connector.
+	* User button near the RCA connectors.
+* LCD touchscreen panel.
+* WiFi module connector (ESP8266) near the user button.
+* 4x MEMS microphones left of the LCD panel.
+
+## Under side ##
+
+* Arduino compatible connector
+* Jumpers to select power source:
+	* 5v USB charger.
+	* 5v power over ethernet (PoE).
+	* 5v external power.
+	* USB OTG.
+	* ST-Link (default).
+
+## How to use the external power ##
+
+Caution: documenting this connector for completeness sake, but we 
+would highly advise against using it, as it appears to be no standard 
+barrel jack connector. Rather it is a special connector designed to take 
+in wires that resemble breadboard wires, which lock into place thanks to 
+a lock-in made for this express purpose.
+
+Let's reiterate that doing this with standard breadboard wires is most 
+probably not a good idea.
+
+This connector is using male pins, so if you wish to use wires, make 
+sure to pick male to female wires.
+
+With the ethernet connector still facing toward you, the pins of this 
+connector are as followed, from **left to right**:
+
+* Ground.
+* 5v power.
+
+## WiFi module ##
+
+If you wish to use WiFi on any project, you could use the 
+[WRL-17146 WiFi module](https://www.sparkfun.com/products/17146) from 
+SparkFun.
