The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.
Level Converter 4 Channel
High voltage is 5V, low voltage is 3.3V
HV connect with 5V power supply
LV connect with 3.3V power supply
GND connect the power negative pole
LVx input/output 3.3V TTL
HVx input/output 5V TTL
Bi-Directional transform between LVx and TVx
Features: Real time location tracking, track playback. Support SMS and GPRS platform tracking. Built-in vibration senor, the realization of vehicle vibration alarm. Micro letter management platform, free control. Mobile client support android, apple system remote control.
