?Key Features :

• Ceramics thermoelectric Cooler semiconductor module TEC1-12706
• Small module.
• Its work is characterized by side refrigeration and side fever.
• Hot and cold on both sides of the temperature difference of 68 degrees
• Connected to the 12-volt power supply cooling piece on both sides there will be the difference in temperature, side cold side of the heat, do not long power cooler radiator, otherwise, it will cause cooler internal overheating and burning.
• Quality tested cooling cells.
• Solid-state, vibration-free, noise-free.
• Simple to install and operate.
• Fitted with 6-inch insulated leads

?Key Features :

1. • DS3231 based RTC with 2032 Battery Holder.
   • Highly Accurate RTC Completely Manages All Timekeeping Functions.

   • Two Time-of-Day Alarms.
   • Programmable Square-Wave Output Signal.
   • Battery-Backup Input for Continuous Timekeeping.
   • Low Power Operation Extends Battery-Backup Run Time.
   • 3.3V Operation.

?Key Features :

1. • Modes?Toggle or switch.
   • Operating current @VDD=3V, no-load, SLRFTB=1.
   • The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V.
   • Sensitivity can adjust by the capacitance(0~50pF) outside.
   • Have two kinds of sampling length by pad option(SLRFTB pin).
   • Stable touching detection of the human body for replacing traditional direct switch key.
   • Provides Fast mode and Low Power mode selection by pad option(LPMB pin).
   • Provides direct mode toggle?mode by pad option(TOG pin), the open-drain mode by bonding option, OPDO pin is an open-drain output, Q pin is CMOS output.
   • All output modes can be selected active high or active low by pad option(AHLB pin).
   • Have the maximum on-time 100sec by pad option(MOTB pin).
   • Have external power-on reset pin(RST pin).
   • After power-on have about 0.5sec stable-time, during the time do not touch the keypad, And the function is disabled.
   • Auto calibration for life.
   • Re-calibration period is about 4.0sec when the key has not to be touched.
