🧩 XY-K Adjustable PWM Signal Generator — 3.3–30 V • 1 Hz–150 kHz • TTL

Panel-mount PWM source with LCD readout and encoder control. Set frequency and duty cycle independently, switch between fine and normal adjustment, and toggle output ON/OFF at the press of a button.

🌟 Highlights

• 🎛 Dual adjustment modes:

  • Normal: 1 Hz–150 kHz, duty step 1%

  • Fine: 1 Hz–15 kHz, duty step 0.1%

• 🖥 LCD display shows live frequency & duty clearly

• 🔄 Separate knobs (encoder) for frequency & duty

• 🔒 Key lock to avoid accidental changes

• 🧠 Serial (TTL) support for external control/integration

• ⏯ Output ON/OFF button

• 🧱 Panel cut-out: 76 × 40 mm (easy dashboard mount)

📐 Technical Specs

• Model: XY-PWM1 / XY-K

• Supply Voltage: 3.3–30 V DC

• Frequency Range:

  • Normal: 1 Hz–150 kHz

  • Fine: 1 Hz–15 kHz

• Frequency Accuracy: ~±2% (per range)

• Duty Cycle Range:

  • Normal: 0–100% (1% step)

  • Fine: 0.0–100.0% (0.1% step)

• Output Amplitude: equals supply voltage

• Load Capability: ~5–30 mA (logic-level drive)

• Operating Temp: −20 to +70 °C

• Mount Opening: 76 × 40 mm

Note: This is a signal generator, not a power driver. To control motors/LEDs, feed its PWM output into a driver or controller that can handle your load current.

🧪 Typical Uses

• Generate square/PWM signals for dev & lab work

• Speed control via motor drivers, servo/stepper interfaces

• MCU input testing, timer/counter evaluation

• PWM dimming experiments and circuit tuning

🔧 Quick Start

1. Power with 3.3–30 V DC (observe polarity).

2. Press ON/OFF to enable the output.

3. Turn the FREQ encoder to set frequency; turn the DUTY encoder to set duty.

4. Hold the lock to prevent accidental changes; switch Normal/Fine for desired resolution.

5. For serial use, connect TTL pins per your controller (baud/protocol per module reference).
