ā” Product Summary: CY-BP227 High-Voltage Mosquito Swatter PCBA
The CY-BP227 (V18-2101) is a compact high-voltage step-up inverter circuit board designed for rechargeable electric mosquito killer rackets and DIY insect-zapping projects. Operating on a DC 3.6Vā5V input, it converts low-voltage battery power into a high-intensity 5,000Vā10,000V output pulse to eliminate flying pests instantly upon grid contact.
š Key Features
- High-Efficiency Boost: Integrates an onboard oscillator and step-up transformer to deliver reliable, instant high-voltage arcs.
- Modern Charging: Includes a tethered Micro-USB sub-board for safe 5V recharging, eliminating dangerous direct-AC mains plugs.
- Complete Controls: Features a tactile zapping button, multi-position sliding power switch, and visual LED status indicators.
- Safety Bleeders: Built-in discharge resistors help bleed residual capacitor energy when the power is switched off.
If you are setting up this module, let me know:
- Do you need a wiring diagram breakdown for the battery and mesh grid connections?
- Are you troubleshooting an issue where the board charges but doesn’t zap?
š Detailed Product Description: CY-BP227 Mosquito Swatter Inverter PCB Module
The CY-BP227 High-Voltage Step-Up Inverter PCBA serves as the core electronic driver module for rechargeable electric mosquito killer rackets and custom pest control DIY projects. Engineered on a rigid, space-optimized rectangular substrate, this circuit board acts as a specialized DC-to-DC voltage multiplier. It efficiently transforms a low-voltage battery supply into a continuous, multi-kilovolt output capable of neutralizing flying insects instantly upon contact. [1, 2, 3, 4, 5, 6]

š Comprehensive Functional Architecture
1. DC-to-AC Inverter Stage (Oscillator)
Batteries natively supply steady Direct Current (DC), which cannot be amplified by regular transformers. To bypass this limitation, the board integrates a built-in oscillation network featuring a high-current transistor (such as the D882). This network chops the stable DC power source into high-frequency pulsating Alternating Current (AC) signals, prepping the voltage for step-up translation. [1, 2, 3]
2. Induction Transformer Network
The generated pulse flows straight into a central step-up induction transformer (the yellow-and-black magnetic core module). This component converts the low-voltage oscillating waveform into an intermediate high-voltage AC current spanning several hundred volts. [1, 2]
3. Voltage Multiplier & Energy Storage
Once stepped up, the current passes through a high-voltage rectification system consisting of fast-switching diodes and a robust, reddish-brown film capacitor. Acting as a solid-state voltage multiplier reservoir, it boosts and levels the output to a staggering 5,000Vā10,000V terminal discharge pulse, instantly dumping its current when an insect bridges the outer protective layers of the racket grid. [1, 2, 3]

4. Integrated Control & Sub-System Interface
- Tactile Spring Activation Switch: A safety press-and-hold push button that activates the high-voltage generation path only during deliberate manual operation.
- Dual-Stage Slider Interface: A mechanical switch selecting overall operation profiles (System Off, Power Active with Status Illumination, or Full Discharging Mode).
- Tethered Micro-USB Breakout: Features an independent micro-USB sub-board link. This design allows convenient, stable frame installations while supporting modern 5V recharging interfaces rather than older, risky direct-AC wall plugs.
- System Status Telemetry: Integrated multi-LED lanes provide visual cues, immediately warning users when the active zap grid is energized or when the charging cycle is active. [1, 2, 3, 4]

ā ļø Critical Safety & Operational Guidelines
-
- Residual Terminal Charge: The capacitor stores dangerous high voltages long after input power is cut off. Never touch exposed solder contacts, terminal pins, or discharge pads without safely discharging the circuit first.
- Insulation Requirements: When installing this board into custom enclosures or repair casings, ensure the high-voltage traces maintain a safe physical clearance from low-voltage lines and metal buttons to prevent accidental arcing or damage. [1, 2]
If you are looking to integrate or repair this board, let me know:-
- Do you need help identifying the exact input/output solder pad locations (e.g., battery leads vs. net lines)?
- Are you planning to swap the micro-USB connector out for a USB-C alternative?
