1602 Display Multi-Waveform Function Signal Generator Experimental PCB Boards MCU Digital RF Signal Generator Kit
Standard Edition full set of spare parts - this package contains the PCB empty board, function signal generator standard version of the required components, schematics and instructions
| Power requirements | 9V - 12V, the positive external negative |
| PCB size | length 81mm X width 57mm |
Functional Description:
Based on the single-chip function of the signal generator, can produce square wave, sine wave, triangular wave, sawtooth wave, inverted sawtooth wave, frequency 1Hz - 20KHz (14 level adjustment). Lite uses LED to indicate the operating mode, can produce square wave, sine wave, triangular wave, frequency 50Hz - 2KHz (5 level adjustment). With button sound.
Standard version of the structure:
