qMCU hardware specifications:The mechanical keyboard is a high-performance Flash microcontroller, supporting USB2.0 (full speed 12Mbps) transmission mode, control, interrupt and batch data transmission functions, and fast response speed. The overall 22-key anti-collision design. That is, the keys Q A Z W S X E D C R F V T G B M Tab Capslock Shift-L Ctrl-L Alt-L Space are pressed at the same time without conflict.MCU hardware parameters are as follows:nHigh-speed, pipelined microcontroller core; power consumption control supports idle mode and sleep mode; internal RAM data memory; 16K * 8Bit FLASH program memory. Working voltage: VDD = 3.3V - 5.5V.qLighting special effect mode switching sequence:l Press "FN" + "\|" to enter the "breathing mode" The overall backlight of the keyboard simulates the breathing rhythm to achieve a curve change from off to the highest brightness of the backlight. l Press again to enter the "left-to-right running mode" and the keyboard backlight will light up from the first group to the fourth group in sequence. l Press again to enter the "right-to-left running mode" and the keyboard backlight will light up from the fourth group to the first group in sequence. l Press again to enter the "diffusion mode" and the keyboard backlight will light up from the middle to both sides in sequence. l Press again to enter the "inward mode" and the keyboard backlight will light up from both sides to the middle in sequence. l Press again to enter the "jumping grid running mode" and the keyboard backlight will light up in the order of one, three, two, and four. l Press again to enter the "single point group lighting mode" and the corresponding group of backlights will light up for 2 seconds when a key is pressed. l Press again to enter the "flowing color mode" and the keyboard backlight brightness will flow and change from left to right in sequence, like the rippling water. l Press again to enter the "off mode" and the overall keyboard backlight will be turned off. l Press again to enter the "constant light mode" and the overall keyboard backlight will be always on.qSide light special effect mode switching sequence:l Press "FN" + "]}", switch to breathing, off, and always on in turn. (Only for 61-key models with side lights)qIndicator light:l The uppercase and lowercase indicator lights are at this key position. Press "CAP" to turn on the function and the indicator lights up; press "CAP" again to turn off the function and the indicator lights off.Color: Black, Quantity: 1, Product size: 300*110*36mm, Packing size: 34*16*4.5cmNote: Due to manual measurement, please allow 1-3 cm deviation.
