PCB_Center
On this PCB there are plugged in two Arduino micros. The red circle marks the Arduino, which is used
for voltage measurement the blue one controls the lights, speed control and servo.
The yellow fuse is dimensioned with 20A and is used to protect the motor and speed controller. On the
left side, there is a red 10A fuse, which protects the ATX-power supply and the mainboard.
The tw0 9 pin connectors (green circle) are used for the two LiPo-Checkers.
In addition, there is a connector for the Bind-Jumper with an included holder for it.(yellow circle)
The connector on the right side of it is used for the R3FS-Reciever.
The two white connectors on the top of the board are used for the two different balancer cables. The
left one is for the 6S-battery the right one for the 2S-battery.
The switch next to them is for choosing between the two operation modes “radio-controlled” (left) or
“autonomous” (right).
The RJ45 socket is for the connection between the PCB_Center and the LED_Control.
The two red 2-pin plugs are for the 2 different batteries. The left one is used for the 22,2V battery the
right one for the smaller one 7,4V battery.
On the two red pin sockets you are able to connect the ATX power supply on the left side which is
plugged in at the mainboard and on the other side there is also a connector for the speed controller.
The black 4-pin socket is for the external power supply.
