Product Introduction： Battery powered equipment Wireless Module,NRF24L01 CC1101 CC2500 etc. Development Board,FPGA/CPLD UNO MEGA2560 PRO MINI 8051c8051 AVR STC etc Camera, Video camera VCR PDA LED Lighting Wireless communication equipment MP3/MP4 player Audio equipment Attention: This is a DC-DC voltage converter module,Must be noted when using: · Input voltage can not be greater than the maximum input range; -Output power can not be greater than the maximum load for along time; ·Input power must be greater than the output power, because thepower consumption of the module itself. Q&A: Q : Why output voltage is less than the nominal voltage? A : Input power supply power is too low.   Test the input voltage witha multimeter, a t this time of the input voltage is very low.
