1Product Features
√Support CAN bus connection, more stable data transmission, less delay, longer distance
√Can bus is applicable to all devices that can run linux, such as Raspberry Pi
√Accessories must not touch metal to prevent short circuit
√On-board TMC2209/TMC2240 driver can be used for extruder
√On-board ADXL345 accelerometer
√Add support for 4.7K resistor (for ntc thermal) or 1.1K resistor (for PT1000) switching
√Can interface no longer use MX3.0 terminal, the new connector supports 15A current, peak 30A
√On-board NTC100k resistor for bin temperature measurement
√ADXL345's INT1 and INT2 are connected to mcu for individual user for leveling
√Heating rod port rated at 5A
√High voltage input limit
√3m CAN connection cable to avoid the trouble of signal loss due to the user's inability to properly crimp the terminals
√Support Plus MAX31865 For PT100
1Product parameters
We constantly optimize our products to achieve the best use state. In order to achieve the best state, our products are produced with high standards.
Product Name:SB2040 Board/SB2040 Pro Board
Product use: Use CAN bus to connect Klipper expansion device
Product type:Voron 2.4 R2 Trident Stealthburner print head
Communication method: CANBUS/USB
Other product attributes: Due to CAN bus communication and KlipperScreen occupy a lot of memory, in Gemini v1/v1.1 motherboard using CAN bus is not recommended to open KlipperScreen. but Gemini v2 can be used at the same time
Peripheral Interface: USB*1, CAN*1, Fan*3, RGB*1, Probe*1, EndStop*2, Temperature Sensing*1, Heating Head*1
Product name:FLY-UTOC Board
12-24V & GND : Power connector
CANBUS : CAN interface , connected to expansion motherboardsand tool boards , etc ( connected to devices with on-board CANtransceiver chips
CANBUS * : For connecting to motherboards withoutCAN port ( only for connecting to STM32 , s USB ( PA11 / PA12 ) portplease pay attention to purchase the corresponding UTOC version )
√The volume is compressed to the extreme , SHT36 adopts a6-layer board design
√Support CAN bus connection , data transmission is morestable , delay is smaller , and distance is longer
√The can bus is suitable for all devices that can run linux , such as raspberry pi
√Accessories shall not touch metal to prevent short circuit

Common problem:
1, UTOC-1 and UTOC-3 what is the difference ah
(1 can only be connected to the lower computer with CAN transceiver, 3 can be connected to those who support CAN but no CAN transceiver lower computer (only stm32, and usb link master control PA11/PA12), can only be connected to two lower computer without transceiver)
2,What terminals are used on the board?
(PH2.0, XH2.54 and XT3.0)
3,What upper computer does Can support?
(Your host system kernel can be used if it supports can)
4,Can the spider be used?
(Can be used)
5,Do I have to buy a can board with UTOC? Or is there anything that needs to be used with UTOC?
(upper computer - usb - motherboard with can port - can tool board, if the motherboard has a can port you do not need to utoc)
