Cooling Fan MOSFET Driver
thingiverse
Purchase the MOSFET driver board for controlling a cooling fan with Sprinter firmware from Carbonfrog's website at http://www.carbonfrog.com/Products/MD305V2.html. This board comes with additional protection diode and suppressing capacitor, making it suitable for various projects. The seller also considered having the boards made with SMDs for a smaller size but requires more orders to proceed. The designer believes this board would be useful for Arduino projects and 3D printer upgrades. If interested in purchasing a kit or modified board, contact the seller. Kits include components and brief instructions, with comprehensive instructions coming soon. The supplied transistor is an IRLML0030TRPBF. To use the board, gather required components such as the RF540A MOSFET, 1N4001 diode, resistors, capacitor, stripboard, male connectors, and solder/wire. Assemble the PCB, wire up, and update Arduino firmware to control fan speed and functionality through commands like M106 (turn on), M107 (turn off), and M106 S127 (set half-speed). Enjoy improved print accuracy with cooling fan options in slicing settings.
