Variable Frequency Signal Generator Module with Display, Front Key Control, USB Power and 3.5Mm Output for Testing Multicolor

Features: Direct Frequency Control: The front keypad works with a four-digit display so users can enter values on the board more easily during electronics projects, repeat setups, and everyday desktop tuning tasks. Simple USB Power Feed: The board uses a USB input with ERP-supported 5V power information and low rated consumption, helping users run the module from common adapters, computers, or portable power sources. Accessible Connection Layout: A 3.5mm output port sits alongside the display and keypad area, making the board easier to use and route when building small electronics tables or circuit workstations. Compact PCB Coil Format: The large spiral coil pattern creates a recognizable board structure with a space-saving footprint, giving hobby users a practical module that fits crowded desktops more cleanly. Electronics Use Orientation: This module is positioned for frequency generation, circuit exploration, and experiment setups, keeping the copy centered on supported board functions instead of unsupported wellness claims.
