Scheme:

„The Matrix 5IN1 II features a significantly more powerful ESC, which has been upgraded from 5A to 12A (18A peak) to meet the high instantaneous power demands of 1S whoop drones. This increase was achieved after thorough testing by integrating 12 MOSFET transistors directly on the board. Together with gold-plated motor connectors, this ensures better conductivity and more efficient power transfer, providing stronger and more responsive thrust.

Built on community feedback for crash resistance, the board now features a 3-point mounting system. This solution creates the necessary cushioning space during impact, reducing stress on key components and reducing the likelihood of damage by up to 80%. Combined with a thicker 1.0mm PCB and optimized component layout, the Matrix 5IN1 II is designed to withstand heavy impacts and serious crashes.

To meet the needs of different pilots, the Matrix 5IN1 II is available in two versions: solderless and soldered. The solderless version comes with motor connectors and power cable already soldered, making installation quick and easy. The soldered version comes with gold-plated JST1.25 connectors and a BT2.0 U-type cable for individual wiring. Larger solder points allow for direct soldering and reduce overall weight.
