FEATURES: - With voltage meter display,voltage meter error of±0.1V, the range of 0~40V. (note: to ensure that the voltage meter accuracy, please make sure that the input voltage is 4.2V or more). - Low light touch button switch measurement input or output voltage,and a light show is voltage measurement which road, and keep the last set, even if the power switch on again. - Voltmeter fine-tuning: hold down the button about 1-2s into fine-tuning mode, can remove button on the calibration at this time. (please do not use standby function, usually). - Low voltage meter can be closed,long press button closure voltmeter (minimum power loss). - Input voltage:4.2~40v(input voltage must be higher than to the output voltage of more than 1v). - Output voltage adjustable range1.25V~37V adjustable (input voltage must be higher than to the output voltage is more than 1V).

Description The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range.

Microchip has gone on to manufacture the PICkit 3, a variation of the PICkit 2 with the same form factor and a new translucent case. It features a faster 16-bit PIC24F processor and a wider voltage regulation range. There are some complaints of it not being as reliable as the Pickit 2. Both PICkit 2 and PICkit 3 have internal, switch-mode voltage regulators. This allows them, in the case of the PICkit 2, to generate voltages from 2.5 to 5 volts, or in the case of the PICkit 3, 2.5 to 5.5 volts, from a 5 V USB supply, at around 100 mA. Both have options for calibrating the output with a multimeter, for increased accuracy. Additionally, for some PICs, the MCLR programming voltage can be generated, at around 13 to 14 volts. This voltage is required to reprogram the flash memory.

PICkit 2 has a separate programmer/debugger unit which plugs into the board carrying the chip to be programmed, whereas the PICkit 1 was a single unit. This makes it possible to use the programmer with a custom circuit board via an In Circuit Serial Programming (ICSP) header. This feature is not intended[3] for so-called "production" programming, however. The PICkit 2 uses an internal PIC18F2550 with FullSpeed USB. The latest PICkit 2 firmware allows the user to program and debug most of the 8 and 16 bit PICmicro and dsPIC members of the Microchip product line. The PICkit 2 is open to the public, including its hardware schematic, firmware source code (in C language) and application programs (in C# language). End users and third parties can easily modify both the hardware and software for enhanced features. e.g. Linux version of PICkit 2 application software, DOS style CMD support, etc.

'-The lamp brightness can be adjusted by requirement,it is very to operate. -It can touch in medium protection,such glass,acrylic,plastic,ceramics and so on,which is very safe. -Wide application of voltage range,you can choose arbitrarily between 2.4V to 4.5V. -Anti power and phone interference,the EFT can reach above /-2KV;the touch response sensitivity and reliability will not affected by the close distance or multi-angle mobile phone interference. -Install: Needn’t to touch copper foil directly,the dimming can be processed across acrylic glass(above 3mm) or plastic. -Application:It can control LED module,light and so on.It is available for indoor LED,lighting lamp,DIY automotive lights dimming refit. -Function:Single touch,using the principle of capacitance touch .-The default function is switch,dimming,with brightness memories LED touch dimming.It will light slowly when turn on the lights,and become dark slowly when turn off,which effectively avoid the stimulation to eyes. -Dimming mode:Non-polar PWM dimming. -Wiring method:PCB board(VCC,GND) is power input,(LED , LED-) is connected with the LED lamps of positive and negative level (fingerprint) touch area, also can wire to lead out (the wiring should not be too long), copper skin area should be 2x3cm. With copper foil copper foil board module will side to the shell side.
