Plug And Play Upgrade For K40 Laser Controllers With LightBurn And LaserGRBL Support 2 Axis GRBL Control PWM Grayscale And 20W To 180W Laser Tubes Easy DIY Cutter Retrofit
UPC:
✔️ 32-bit GD32 MCU with integrated A4988 drivers and high-speed data
The plug-and-play upgrade is a direct drop-in replacement for M2/M3 Nano boards in K40 laser systems. It matches standard M2/M3 hole spacing for a true plug-and-play swap with no drilling. Baseline speeds are optimized for 0-500 mm/s, with room for higher speeds if your frame allows. It enables PWM grayscale control and includes safety features for peace of mind.
✅ 32-bit GD32 MCU with integrated A4988 drivers for smooth G-code
✅ PWM grayscale control 0-100% enables high-detail engravings
✅ Safety features include static laser protection and lid protection
✅ Plug-and-play compatibility with M2/M3 Nano boards
