HW-209 5V Five-way HUO Flame Sensor Module 8-way Level Conversion Module Suitable for Raspberry Pi

The V2 upgrade version 1 VCCA and VCCB add a set of power supply interface for example PI connected to the 5V sensor V1 version VCCA VCCB connected 3 3V and 5V power supply there is no extra power port to the 5V sensor power supply V2 new version 2 side increase A set of power ports 5V sensor power can be inserted directly on the VCCB users do not have their own DIY power cord 2 V2 version of the power interface to increase the 4 filter capacitor relative to V1 more stable and reliable Product Features As the Raspberry Pi GPIO is 3 3V so then the conventional 5V sensor is very convenient So this product to achieve 8 channel high voltage and low voltage bi directional conversion to achieve Ax and Bx bidirectional turn Conversion level range 1 8V 6VInstructions for use 3 3V 5V interchange for example VCCA picks up raspberry 3 3V power supplyVCCB 5V power supply can be an external 5V power supply GND connected to the power supply negative two power supply groundAx input raspberry to send 3 3V TTL level Bx will output 5V sensor module TTL levelBx input 5V electronic module TTL level Ax will output raspberry to send 3 3V TTL levelPackage included 1 x HUO flame sensor module
