Description
Product Description
The Anti-Reverse Bluetooth PCB Carrier Board is a professional-grade interfacing solution designed to host and protect standard Bluetooth serial modules (such as HC-05, HC-06, and HM-10). Engineering mistakes during prototyping—specifically reversing the power supply—are the leading cause of module failure. This carrier board solves that problem with an integrated anti-reverse protection circuit, ensuring that your Bluetooth module remains safe even if the VCC and GND wires are accidentally swapped.
Beyond protection, this board features a high-efficiency onboard power management system that supports a wide input voltage range (3.6V to 6V) and provides stabilized 3.3V power to the mounted module. With built-in level-shifting circuitry, it allows for direct, safe communication between 3.3V Bluetooth chips and 5V microcontrollers like the Arduino Uno. This is the ideal “safety-first” baseboard for educational kits, industrial sensor nodes, and rapid prototyping.
Key Features
- Active Anti-Reverse Protection: High-speed protection circuitry prevents module burnout if power polarity is reversed.
- Ultra-Low Power Architecture: Optimized trace layout and low-dropout (LDO) regulator minimize idle current, extending battery life for portable IoT applications.
- Universal Module Compatibility: Designed with standard 1.5mm/2.0mm pitch pads to accommodate HC-05, HC-06, HM-10, and AT-09 Bluetooth modules.
- Onboard Logic Level Shifting: Safely bridges 3.3V Bluetooth signals with 5V TTL systems without the need for external resistor dividers.
- Clear Status Indication: Dedicated pads for a status LED provide visual confirmation of pairing and connection states.
- Industrial Build Quality: High-quality FR-4 PCB material with gold-plated finish for superior solderability and corrosion resistance.
