Features:

- Designed for Voron Stealthburner

- Integrated ADXL345 Accelerometer

- Supports PT1000 via pull-up resistor

FLY SB2040 is a nozzle tool board for the VORON Stealthburber printhead. It integrates a CAN transceiver, USB port, TMC2209 driver, ADXL345 acceleration sensor, two controllable fans and other functional tool boards. This toolboard is for Klipper firmware.

Onboard TMC2209 driver, using UART mode, can be used for extruders

Onboard ADXL345 acceleration sensor

Supports leveling sensors such as BLTOUCH and PL08N, and integrates XY limit switches

Support 12-24V voltage input

MCU: Raspberry Pi rp2040, Dual core ARM Cortex-M0+@133MHz

Added support for 4.7K resistor (for ntc thermistor) or 1K resistor (for PT1000) switching

The can interface uses XT30 (2+2), supports 15A current, peak value 30A

Add onboard NTC100k resistor for measuring warehouse temperature

Add INT1 and INT2 of ADXL345 to be connected to MCU for individual users to use for leveling.

Support high voltage input limit

A 3-meter CAN connection cable is provided to avoid the problem of signal loss caused by users’ inability to press the terminals correctly.

Support 2/3/4 line fans

Split design, Stealthburner is easy to disassemble

Compatible with Hartk's Stealthburner Toolhead Board (the fan board does not need to be replaced)

Interface: Controllable fan*3, RGB*1, limiter*3, heating tube*1, thermal*1
