E-sports magnetic axis keyboard scheme uses SK985 master chip with high-performance SOC Bluetooth chip SK528, supports USB, Bluetooth and 2.4G connection modes, working distance can reach more than 10m in wireless mode, dormancy current in wireless mode is as low as 220uA, trigger stroke is 40 segments adjustable, support automatic calibration, dynamic keypad DSK, RT fast trigger, and can be equipped with touch slider, human body sensing and other features. Magnetic axis matrix scanning and RGB lamp scanning can be completed with a single chip, and there is no need to add a lamp driver chip to support a variety of magic lighting effects to help players experience the extreme lighting atmosphere. The scheme supports the driver software to configure various keyboard parameters, and users can make personalized settings to get a better game experience.

In fact, the realization principle of the magnetic axis can be simply understood as: when a conductor is connected to the circuit, the charged particles will move along the shortest path, and when a magnet approaches along the vertical direction of the conductor, the negatively charged particles will deflect in one direction, and the positively charged particles will deflect in the opposite direction. At this time, the weak voltage can be detected by measuring both ends of the conductor with a voltmeter. The closer the magnet is to the conductor, the greater the deflection of the charged particles and the greater the voltage. If the voltage exceeds the threshold, it is regarded as a protective cover by iPad and the screen can be locked. For magnetic axis keyboards, setting a voltage threshold for each key can be regarded as a key being pressed. Compared with the characteristics that each key of the mechanical key shaft needs to be pressed to the end, and then restored to the original position, the magnetic shaft can adjust the pressing length to achieve a single click on a short press and short lift, and then achieve fast press of the key. Suppose the key cap is pressed to the bottom for a total of 4mm, and the mechanical key shaft is pressed and popped up, once the key command is 8mm, and 10 times is the stroke of 80mm; suppose the magnetic axis is pressed to trigger and adjusted to 1mm, the magnetic axis is pressed and popped up, the key command is 2mm, and 10 times is the stroke of 20mm.
