Сигнал генератор 1Hz~150kHz → Обява 43718195

Parameter:
1. Working voltage: DC 3.3v~30v
2. Frequency range: 1Hz~150kHz (divided into 4 ranges);
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 for experimental development;
2. As square wave signal generator for motor driver;
3. As adjustable pulse generator for MCU;
4. As pulse generator, control related circuits (PWM dimming, speed regulating).

Setting Parameters:
There are 4 independent buttons on the module for setting the frequency value and the duty cycle value.
Supports short press (increase or decrease 1 unit by 1 unit) and long press (fast increase or decrease).
All setting parameters will be saved when powered off to achieve data guaranteed.

Frequency Display Instruction:
The frequency is divided into 4 ranges and switched automatically.
1. XXX (without decimal point): minimum unit is 1Hz, value range is 1Hz~999Hz.
2. X.XX (the decimal point is in the hundred digit): minimum unit is 0.01kHz, value range is 1.00kHz~9.99kHz.
3. XX.X (the decimal point is in the ten digit): minimum unit is 0.1kHz; 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 displays 100 represents 100Hz; displays 1.01 represents 1.01kHz;
displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHz
