-PWM1/2 connector has standard RC-servo compatible pinout. In both connectors there are two vertically placed RC-servo pinouts (signal, supply, ground) therefore up to 4 RC-servos can be driven. Controller board supplies up to 2 A total from supply pins. PWM1/2 connector can also be used to drive DC motor which should be connected between leftmost PWM signal pins. Those signals are driven by 600 mA MOSFET half-bridges and can form a full h-bridge.

+Both ADC1 and ADC2 connectors have two RC-servo like pinouts. There are ground, supply and input-output pins. It is easy to connect simple sensors like potentiometer, thermistor, IR distance sensor and ultrasonic distance sensor to these pins. I/O pins can be used as +5 V compatible inputs or outputs with +3.3 V high level. These connectors can also be used to control RC-servos with software PWM when the servo accepts 3.3 V signal.

-~~CL~~
+COMM connector is a combination of UART, SPI and I2C interfaces. Beside the +5 V supply it contains +3.3 V supply which supplies up to 700 mA. COMM connector is intended to connect with ARM-CAN User Interface and that is why it also features 2 ADC and 1 PWM pins, which are used by the joystick and speaker.

+ARM-CAN Controller board has a standard 20-pin JTAG connector with essential pins for programming and debugging. Although the kit contains ARM-CAN programmer, other standard ARM debuggers can be used.

+==== CAN ====
+[{{  :images:hardware:arm-can:connectors:controller_can.png|CAN connector(s)}}]
+ARM-CAN Controller board contains two identical CAN 10-pin header connectors. Both of the connectors are on the same bus, therefore CAN network can be formed by daisy-chaining several Controllers. There is no CAN signal terminator on the Controller board so external terminators should be used.
+Microcontroller CAN RX and TX pins which connect to the on-board CAN translator are marked with orange color on the image.

+==== USB ====
 [{{:images:hardware:arm-can:connectors:controller_usb.png|USB pins}}]
+~~CL~~
+The controller board incorporates the USB micro-AB connector on the right side. Although micro-AB is intended for OTG applications the same connector can be used for device-only and host-only applications. USB inteface has ESD protection on bus and 750 mA fuse on supply line. USB power supply is bi-directional. When  the controller acts as a USB device, current from the USB bus to controller board flows through a Schottky diode, when the controller is used as a host, external power switch to USB bus can be opened with USB_EPEN high signal.
+~~CL~~
+==== RGB LED ====
+[{{  :images:hardware:arm-can:connectors:controller_rgb.png|RGB LED pins}}]
+In the middle of the controller board there is a 350 mW RGB LED. Each of the three colors are driven by separate signal. Green LED has a pull-up resistor which lights up green led by default. It can be turned off when microcontroller pin is configured as output with low signal.
+~~CL~~
+==== Buttons ====
+[{{  :images:hardware:arm-can:connectors:controller_btn.png|BTN pin}}]
+There are two buttons on board. The left one resets microcontroller when pressed; the right one is used as a custom button for user application. The button has an RC filter which filters button bounces.
