| Parameter Category | Item | Specification Details |
|---|---|---|
| Basic Parameters | Module Model | 8-Key Game Controller (A053) |
| Basic Parameters | PCB Outline Dimension | 99.00mm × 49.50mm |
| Basic Parameters | Key Layout | 4 directional keys on the left: UP/DOWN/LEFT/RIGHT + 4 function keys on the right: A/B/C/D |
| Basic Parameters | On-board Hardware | RGB status indicator lights, FPC cable interface, key mounting holes |
| Basic Parameters | Key Type | Tactile keys, replaceable with mechanical game keys with keycaps |
| Basic Parameters | Communication Method | FPC cable output, supports matrix keyboard scanning / I2C, determined by driver program |
| Basic Parameters | Supply Voltage | 3.3V~5V DC, 5V recommended |
| Basic Parameters | Product Weight | Bare PCB: approx. 14g; Finished board with soldered keys & indicators: approx. 22g, weight tolerance ±1g for mass production |
| Key Zone - Direction Key Area | UP, DOWN, LEFT, RIGHT, cross directional control input | For vertical & horizontal movement control; commonly used for game character movement and menu cursor switching |
| Key Zone - Function Key Area | A, B, C, D, customizable confirm/cancel/skill and other functions | Different functions can be assigned via program, suitable for skill triggering, option confirmation, return & cancel operations |
| FPC Cable Interface Pin | VCC | Positive power supply of the module |
| FPC Cable Interface Pin | GND | Negative power supply; must share ground with MCU |
| FPC Cable Interface Pin | UP | Signal output of UP directional key |
| FPC Cable Interface Pin | DOWN | Signal output of DOWN directional key |
| FPC Cable Interface Pin | LEFT | Signal output of LEFT directional key |
| FPC Cable Interface Pin | RIGHT | Signal output of RIGHT directional key |
| FPC Cable Interface Pin | A/B/C/D | Independent signals for four function keys |
| FPC Cable Interface Pin | LED | Control pin for RGB indicator lights |
| Core Feature | Matrix Scanning Architecture | Adopts matrix keyboard scanning. Only a small number of IO ports are required to read status of all 8 keys, saving main controller resources |
| Core Feature | RGB Light Feedback | Built-in RGB indicators. Programs can be compiled to realize lighting effects upon key trigger and status prompting |
| Core Feature | Expandable & Modifiable | Reserved key mounting holes; supports replacement with larger mechanical game keycaps for better hand feel |
| Core Feature | Low-Latency Input | Tactile keys feature fast rebound and low response delay, ideal for games and real-time motion control scenarios |
| Packaging Option | Optional Packages | ① Anti-static soft bag ② White hanging-hole card box ③ Kraft paper box |
