3ft Orange RG-178 Coaxial Cable with SMA Male to SMA Female Connectors
This 3-foot RG-178 coaxial cable is ready to help you extend the capacity of your data infrastructure. Coaxial cable is a type of shielded, electrical conducting cable used to transmit analog and digital signals. The initials RG stand for Radio Guide and are used to describe different types of coaxial cable. RG-178 cables are most commonly used for transmitting high-frequency signals. As such, they are often employed for the purpose of cabling between Wi-Fi routers and antennas. The SMA male and SMA female connectors that terminate this cable are also widely compatible with many wireless network implements. SMA stands for SubMiniature version A and is a form of RF coaxial connector with 50 ohms impedance and a performance frequency of up to 18GHz. SMA connectors feature a screw-type coupling mechanism and are frequently employed in bulkheads and patch panels because of the their diminutive size. For a widely compatible, resilient addition to your data infrastructure, look no further than this 3-foot RG-178 coaxial cable with SMA male to SMA female connectors.

Description:
 
Input voltage 2.8 - 6V, output 6V (deviation -5% )
Maximum input current:  1.5A
Long-term work Current : 1A 
Conversion efficiency : 90%
 
PCB size : 25MM x 15MM
 
Start Voltage 2.8V, Output Current 100MA
INPUT 3V   1A; OUTPUT 6V 430MA
INPUT 3.3V 1A; OUTPUT 6V 490MA
INPUT 3.7V 1A; OUTPUT 6V 550MA
INPUT 4.5V 1A; OUTPUT 6V 670MA
INPUT 5V   1A; OUTPUT 6V 750MA
 
This is with on/off switch voltage boost module.The master chip is FP6291GLR
Can used  the input voltage (VIN or GND)control  the switches,also use MCU IO control the switches.
Control current is very small, MCU IO port can be directly controlled. Including micro-controller : ARDIUNO UNO MEGA2560 AVR STM32 ARM PIC AT89C51 STC MSP430 FPGA CPLD etc.
 
When the EN pin  = GND(OR MCU LOW level),the boost module is working properly;
When the EN pin  = VIN(or MCU HIGH level,3.3V/5V) OR Not Connected(or MCU High impedance),
the boost module into standby mode, stops working, the output voltage is 0V(Can measure the output voltage is 500~800MV, which is inductive output voltage,you  does not have to bother).

Attention :
    
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power 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 with a multimeter,a t this time of the input voltage is very low

Qty: 1 pcs step-up modules (input DC 5V , output DC 9V ) ;
 
Description: 
 
 
Note: The output current is no current limit! is capable of carrying up to 2A peak input current, But output power cannot exceed 5W ,otherwise the heat will become big problems!
Tips: This module supports sleep mode, remove the LED indicator the sleep current 50mA,250-350 mA current can support the one-year standby mode! The micropower environment more suitable for special use .
 
 
Attention : 
1: Boost modules or buck module indicate the operating voltage, Please donot exceed operating voltage , or it will be damaged easily !
2: Boost module output voltage can only be greater than or equal to input voltage, cannot be less than the input voltage!
3: Buck module input voltage must be higher than output voltage of 1.5V or 2V, otherwise it can not output enough power!
4: Automatic Adjustable Boost or Buck module has start voltage and limit working voltage, Please donot exceed them , or it will be damaged easily !
5: Cannot reverse polarity , or it will be short circuit, or will be  born easily !
