The small variant of the OptoTap board, suitable for small printers and solutions like Boop or MetalBoop.
Comes with the Optek OPB666N sensor (rated to 100°C)
This small and handy PCB allows you to connect devices in parallel - no matter if they are using PH, XH, or a combination. Even right-angle connectors are supported.
Note that the maximum current is 2A total.
PCB Size 60x12mm, Screw Hole Distance 48mm, Mounting hole Diameter=3.2mm, max. Screw Head Size 6.4mm.
If you intend to screw this onto an extrusion, make sure you use plastic spacers to prevent the pins shorting out.
40x40x28mm fan for use in the Nevermore Mini. Very powerful fan which can be controlled via the PWM pin down to sub-10%.

PWM control
PWM control follows the standard Intel Spec (5V pullup, 25kHz signal). If no signal is given via the PWM input, the fan will run at full speed. Relevant config options for Klipper:
tachometer_pin: # Set to the pin you like to use. Make sure it has either a hardware or software pullup
tachometer_ppr: 2
tachometer_poll_interval: 0.001
cycle_time: 0.00004
hardware_pwm: true # Hardware PWM is preferred if your board is capable of it

To extend JST XH connections. JST XH is a 2.5mm pitch connector series, used on most mainboards and the EBB36 / SHT36 toolheads. JST officially does not make these extenders, but we were able to source them from 3rd party manufacturers
Contents:
10x 2 pin housing
10x 3 pin housing
10x 4 pin housing
100 crimp contacts
JST PH is a 2.0mm pitch connector series, used on boards like the EBB36 (for the endstops), SB2209 RP2040 and Mellow SB2040 series. JST officially does not make these extenders, but we were able to source them from 3rd party manufacturers

Replacement SB0000 PCB. Comes without any crimp contacts or connector housings. If you need some, please let us know (order comment) and we can throw some in for free (be reasonable, and tell us what you need exactly).
Important: Please use plastic washers between the screw and the PCB, otherwise you can easily damage the traces on the PCB. A printed washer works fine.
Orion OD4010-24HB01A with tachometer output, suitable as StealthBurner Hotend Fan

Nitehawk is a toolhead PCB with a RP2040 MCU, TMC2209, Accelerometer all integrated into one board. The form factor is based on HartK’s two piece stealthburner toolhead PCB but with some minor changes.
Greatly simplified wiring, a single wire runs through the drag chain or in an umbilical setup. No additional breakout cables needed.
Based on Klipper USB, no additional hardware or software setup compared to CAN.
Tachometer enabled fan ports (PCF and HEF), allowing for fan speed detection.
Integrated accelerometer for convenient input-shaping

These fans have the Nevermore logo cap put on in an offset and cause vibrations. You need to remove the logo cap to prevent the vibrations, hence B-Stock.
A sharp cutter knife can be used to cut through the foam tape gluing logo cap and fan together.
