PWM Frequency Meter XY-PWM LCD Display PWM Generator 1Hz-150kHz

Selamat Datang Parameter: 1. Working voltage:3.3v~30v 2. Frequency range: 1Hz~150kHz (divided into 4 range); 3. Frequency precision: 2% of each range; 4. Signal load capacity: output current is about 5-30mA; 5. Output Amplitude: PWM amplitude equal to the input voltage value 6. Environment Temperature Range: -20~+70℃ 7. Duty cycle range: 0-100%. Application: 1. As square wave signal generator to generate a square wave signal for experimental development; 2. Generate square wave signal that controls the motor driver; 3. Generate adjustable pulses used by the MCU; 4. Generate adjustable pulses, control related circuits (PWM dimming speed adjustment applications, etc.) Setting Parameters: There are 4 independent keys on the module for setting the frequency value and the duty cycle value. Supports short press (increase or decrease one unit) and long press (fast increase or decrease). All setting parameters will be saved if powered off to achieve data guaranteed. Module Instruction: The frequency is divided into 4 ranges and can be switched automatically. 1. XXX (without decimal point): the minimum unit is 1Hz, and the value range is 1Hz~999Hz. 2. X.XX (the decimal point is in the hundreds) the minimum unit is 0.01kHz, and the value range is 1.00kHz~9.99kHz. 3. XX.X (the decimal point is in the ten digits): the minimum unit is 0.1kHz; and the value range is 10.0kHz~99.9kHz. 4. X.X.X (full decimal point): the minimum unit is 1kHz; the value range is 1kHz~150kHz e.g. Frequency display: 100 represents 100Hz; 1.01 represents 1.01kHz; 54.1 represents 54.1kHz; 1.2.4 represents 124kHz Jika Tidak Request Maka Kami Kirim Random Beli = Setuju No Komplain No Retur Wajib Video Unboxing Dari Awal Sampai Akhir Tanpa TerJeda Jika Komplain
