==== Connector Definitions ====

^ Connector      ^ Description       ^ 
| CAN1    | UAVCAN main connector. Identical to CAN2 port, can be used for linking to another UAVCAN device or terminator.|
| CAN2    | UAVCAN main connector. Identical to CAN1 port, can be used for linking to another UAVCAN device or terminator.|
| C5V     | C5V is connected to CAN1/2 power line and protected with a 500mA automatic fuse. |
| 3V3     | 3.3V LDO regulated output pin. Same LDO provides power to the main MCU. Max output 3.3V/300mA. |
| C2      | C2 / Tx1  |
| C1      | C1 / Rx1  |
| B2      | B2 / Tx2 / TLM  |
| B1      | B1 / Rx2  |
| A2      | A2 / SCL  |
| A1      | A1 / SDA  |
| GND     | Common ground, used to ground your additional hardware. |
| EXT5    | External 5V input if you need more power than what the C5V line can provide. |

==== Firmwares ====

There are //**two**// main softwares for this board. One is the bootloader and another is the operation firmware. Please do not mix them. The firmware you upload with the SLCAN board over the UAVCAN databus. The bootloader is uploaded via the SWD connector. 

This board is coming with the latest UC4H Bootloader uploaded at jDrones. Normally you do not need to upload it unless you want to upgrade it or have "bricked" your UC4H board. You need a [[can:stm32prg|jDrones STM32 Programmer]] for burning the bootloader into this board. 

You can always download the latest firmware and bootloader from our document site.

Firmwares/Bootloaders, please take a look at our [[can:firmwares|firmware page]].
