-The BeagleBone Blue is a single board computer with a 1GHz [[embedded_systems:ti_sitara_am335x:start|Texas Instruments Sitara AM335x]] (single core) and 512 MB RAM. Further, there is a HDMI connection, 2 GB eMMC Flash, USB, Ethernet, microSD and various digital I/O and ADC.+The BeagleBone Blue is a single board computer with a 1GHz [[embedded_systems:ti_sitara_am335x:start|Texas Instruments Sitara AM335x]] (single core) microprocessor together with wifi/bluetooth, IMU/barometer, power regulation and state-of-charge LEDs for a 2-cell LiPo, H-Bridges, discrete connectors for 4 DC motors+encoders and 8 servos.

 +Detailed electrical information about the board can be found in the {{ :embedded_systems:ti_sitara_am335x:beaglebone_blue:beaglebone_blue_sch.pdf |schematic}}. Pin numbering and multiplexed functions are described in [[ https://github.com/beagleboard/beaglebone-blue/blob/master/BeagleBone_Blue_Pin_Table.csv]]
  
  
 ===== WiFi ===== ===== WiFi =====
-When connecting to a WiFi, always make sure that both physical antennas are aligned correctly away from the board as follows: \\ \\ {{:embedded_systems:ti_sitara_am335x:beaglebone_blue:beaglebone_bluebbblue-ttl-3.png?400|}}+When connecting to a WiFi, always make sure that both physical antennas are aligned correctly away from the board as follows: \\ \\ {{:embedded_systems:ti_sitara_am335x:beaglebone_blue:beaglebone_bluebbblue-ttl-3.png?400|}} \\ \\ 
 +For WiFi configuration there are the following three files with the following content involved (Depending on the Linux image it may also work by just configuring the first file): \\ \\ 
 + 
 +''/etc/wpa_supplicant.conf'' : 
 +<code> 
 +network={ 
 +    key_mgmt=WPA-PSK 
 +    ssid="<mySSID>" 
 +    psk="<myPassword>" 
 +} 
 +</code> 
 + 
 +''/etc/systemd/network/30-wlan0.network'' → if the file does not exist, just create it: 
 +<code> 
 +[Match] 
 +Name=wlan0 
 + 
 +[Network] 
 +DHCP=ipv4 
 +</code> 
 + 
 +''/etc/systemd/system/udhcpc.service'' : 
 +<code> 
 +[Unit] 
 +Description=Start udhcpc DHCP client 
 +After=wpa_supplicant.service 
 +Wants=wpa_supplicant.service 
 + 
 +[Service] 
 +Type=oneshot 
 +ExecStart=/sbin/udhcpc -i wlan0 
 +TimeoutSec=30 
 +Restart=on-failure 
 + 
 +[Install] 
 +WantedBy=network.target 
 +</code> 
 + 
 +After a reboot you can check the IP address of the according ''wlan0'' interface by executing the following command: 
 +<code> 
 +sudo /sbin/ip a 
 +</code>
