Modul 2 Channel Adjustable PWM Generator dengan Display Indikator

Detail Modul 2 Channel Adjustable PWM Generator dengan Display Indikator

1. Dua jalur PWM, dapat diatur frequency dan duty cycle.
2. Frekuensi lebar dan presisi.
3. Bisa menggunakan komunikasi serial
4. Ukuran: 41 * 28mm tebal: 1.6mm

Frekuensi terbagi tiga :
1. XXX (tanpa titik desimal): unit terkecil 1Hz, range 1Hz ~ 999Hz.
2. XX.X (titik desimal skala 10): unit terkecil 0.1Khz; range 0.1KHz ~ 99.9KHz.
3. X.X.X. (3 titik desimal): unit terkecil 1Khz; range 1KHz ~ 150KHz.

Tampilan display:
100 berarti keluaran PWM sebesar 100Hz.
54.1 berarti keluaran PWM sebesar of 54.1 kHz.
1.2.4. berarti keluaran PWM sebesar 124 kHz.

Parameter settings
Module has three buttons are: Set, Up, Down
1. dU1: duty cylce PWM1, FR1: frequency PWM1, dU2: duty cycle PWM2, FR1: frequency PWM1
2. Press the Up, Down buttons to change the current parameter value (long press to fast or fast down).
3. Two PWM each preset three kinds of frequency value, in the frequency display interface

Specs:
1. Operating voltage: 5 - 30V support micro USB 5.0V power supply
2. Frequency range: 1Hz ~ 150KHz
3. Frequency accuracy: the accuracy in each range is about 2%
4. Signal load capacity: the output current can be 8 - 30ma or so
5. Output amplitude: default 5V V-pp (can be changed by external power supply)
6. Ambient temperature: -30 ~ +70 ℃.

Application:
1. Used as square wave signal generator, generate square wave signal for experimental development and use
2. Used to generate a square wave signal that drives the stepper motor driver
3. generate adjustable pulse for MCU use
4. Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).

Serial control
Baudrate: 9600 bps
Data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
