PWM signal generator module, 3.3-30V, 1-150KHz, serial, adjustable frequency and duty cycle
Compact PWM generator for fine tuning frequency and duty cycle, ideal for motor control, LED lighting, testing and automation. It operates at 3.3-30V and covers 1Hz-150KHz, allows quick adjustment from buttons and TTL RX/TX serial control, and the internal memory saves the last setting when the power is turned off.

PWM (Pulse Width Modulation) signal generator module, with the possibility to set the frequency and the duty cycle and the possibility of control through the serial interface.
The module keeps in memory the last setting when the power supply is interrupted.
It has 4 buttons that adjust the frequency and Duty Cycle, the short press is used to change the values and the long press of the buttons for the quick change of the values.
The frequency is divided into 4 resolutions with automatic switching:
- XXX, without decimal points, the smallest unit is 1Hz, values between 1Hz and 999Hz
- X.XX, decimal point in hundredths, the smallest unit is 0.01KHz, values between 1.00KHz and 9.99KHz
- XX.X decimal point in tenths, the smallest unit is 0.1KHz, values between 10.0KHz and 99.9KHz
- XXX, decimal point in tenths and hundredths, the smallest unit is 1KHz, values between 1KHz and 150KHz
Display example:
- 100 indicates PWM 100Hz
- 1.01 indicates PWM 1.01KHz
- 50.1 indicates PWM 50.1KHz
- 1.2.3 indicates PWM 123KHz
Specifications:

Frequency accuracy: 2%
Output type: PWM
Waveform: Square
Serial control: Yes, TTL, through the RX and TX pins
Output load capacity: 5 - 30mA
Output amplitude: PWM amplitude equal to the supply voltage
Operating temperature: -20 - 70 degrees C
Dimensions mm: 52 x 32mm
Serial communication:

- PWM frequency setting:
"FXXX", "FX.XX", "FXX.X", "FX.XX", where X is replaced by the desired values
- Setting PWM Duty Cycle:
"DXXX", where X is replaced with values between 0 and 9 (example: "D050" sets Duty Cycle to 50%)
- Reading parameters:
Use the "read" syntax to read the set parameters.
The successful setting returns "DOWN", the failed one "FALL".

Trebuie schimbata sursa de alimentare sau alimentate de un dc/dc ...altfel se ard rapid si la varianta alimentate cu 5 v rezistenta de 33 ohm serie cu ledul de lumina de la afisaj....em am pus 100 ohm cu 33 in varianta 5 v dupa 3 zile de functionare a inceput sa clipeasca random. ..adica sa dus ledul ...alimentate de o sursa dc/dc merg bine si pe auto unde sunt fluctuatii mari de tensiune
Generatorul funcsioneaza stabil si suficient de precis pana la circa 100 kHz. La valori ale frecvenaei de peste 100 kHz factorul de umplere are abateri nesistematice, deci dificil de corectat. Patii de reglaj, atat an frecvenaa cat si pentru factorul de umplere, sunt relativ grosieri, fapt important numai an aplicatii an care se realizeaza masuratori sau reglaje fine ale funcsionarii altor montaje electronice. Pentru aplicatiile uzuale (controlul turatiei sau al tensiunii medii debitate pe sarcini rezistive) funcsioneaza foarte bine si suficient de reproductibil.
funcsioneaza
foarte bun
