-==== Board definition ====
+This is jDrones version of the UC4H SLCAN adapter board. Documentation is accurate only if you are using original jDrones SLCAN boards.
-Picture of SLCAN board with quick definitions. Look below to more detailed definitions of the board.
+To connect to your UAVCAN bus, you need an SLCAN adapter and software to read the UAVCAN messages. Pavel K., the author and maintainer of UAVCAN, has created a fantastic software for UAVCAN operations.

-==== Connection definitions ====
+==== Connector Definitions ====
 ^ Connector      ^ Description       ^
-| USB    | USB connection to your computer. This serial port USB uses Silabs CP2102 Serial adapter. Make sure that you always have latest drivers installed for CP2102. \\ \\ You can download latest drivers from [[https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers|Silabs website]]  |
+| USB    | USB connection to your computer. This USB port uses a Silabs CP2102n serial adapter. Make sure that you always have latest drivers installed. \\ \\ You can download latest drivers from [[https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers|Silabs website]].  |
-| UART2  | UART port from MCU, used only for debugging needs and using this port needs custom firmware to be activated. Normally not in use |
+| CAN2   | 4 Pin, JST-GH connector for official UAVCAN cables. Same as CAN1 port. |
-| SWD    | Onboard STM32 programming port. Connector pitch is 1.27mm. This port is used to program SLCAN firmware on the board. Best to use jD-STM32 Programmer + 1.27mm pogopin adapter board to program SLCAN board. You can get jD-STM32 Programmer from [[http://store.jdrones.com/jdrones_stm32_programmer_p/jdstm32prg10.htm|jDrones Store]]. \\ \\ Pin order from left to right: //GND, SWCLK, SWDIO, 3v3// \\ \\ __**BEWARE** Always check orientation of the programmer.__ This port is not reverse polarity protected.  |
+| CAN1   | 4 Pin, JST-GH connector for official UAVCAN cables. Same as CAN2 port. |
-| EC5V   | External 5V input for UAVCAN devices. If you don't use //Bridge Jumper (BR1)// you need to provide 5V voltage to your UAVCAN devices. Use this connector head to activate C5V output. |
+| CP1    | Jumper cable pin header for CAN bus. |
-| TR1    | CAN BUS Termination header. Usually you have terminator block connected in here and ONLY in rare cases you need to take terminator out. All CAN Busses must have at least one termination or bus is not working correctly. \\ \\ Terminator block connects CAN-L and CAN-H pins with //120 Ohm// resistor.|
+| TR1    | CAN bus termination header. Usually a termination block is connected here. Only in rare cases the termination needs to be removed. CAN buses must have at least one termination, or the bus won't work correctly. \\ \\ The termination block connects CAN-L and CAN-H pins with a 120 Ohm resistor.|
-| CP1    | Jumper cable pin header for UAVCAN bus. |
+| BR1    | 5V -> C5V bridge jumper. Short this jumper to provide 5V from your USB bus or the External 5V Input port (EXT5) to the CAN bus. |
-| CAN2   | 4 Pin, JST-GH connector for official UAVCAN cables. Same as CAN1 port |
+| EXT5   | External 5V. If the power provided by the USB bus is not sufficient and the CAN bus needs to be powered by the SLCAN adapter, apply power to this port and shorten the BR1 jumper. |
-| CAN1   | 4 Pin, JST-GH connector for official UAVCAN cables. Same as CAN2 port |
+| EC5V   | Direct connection to the CAN 5V line. If the power provided by the USB bus is not sufficient and the CAN bus needs to be powered by the SLCAN adapter, apply power to this port but //**keep the BR1 jumper open**//! Use with care. |
-| BR1    | 5V -> C5V Bridge jumper. Short this jumper to provide 5V from your USB to CAN bus |
+| SWD    | STM32 programming port. Connector pitch is 1.27mm. This port is for uploading the SLCAN firmware. Use the [[can:stm32prg|jDrones STM32 Programmer]] together with the 1.27mm pogopin adapter board to program the SLCAN board. You can get the jDrones STM32 Programmer from [[http://store.jdrones.com/jdrones_stm32_programmer_p/jdstm32prg10.htm|jDrones Store]]. \\ \\ Pin order from left to right: //GND, SWCLK, SWDIO, 3.3V// \\ \\ __**BEWARE** Always check the orientation of the programmer.__ The SWD port is not reverse polarity protected.  |
-| EXT5   | External 5V |
+| UART2  | UART port of the MCU. Used only for debugging purposes and requires custom firmware. Normally not in use. |
