   • 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.

Key Features:

• NEW IMPROVEMENT: Clear prints on the female header connector, more precise and easier to use the wire.
• The ELEGOO UNO R3 BOARD now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory.
• Control using ATMEL ATMEGA328P chip(the same with Arduino UNO R3)
• 100% compatible with the Arduino IDE and RoHS Compliant
• The Uno board can be powered via the USB connection.
• The Uno board can be powered with an external power supply.
• Excellent welding and production quality to make sure satisfied customer experience
• The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer.
• We have always cared about the customer experience and improve the product function details.
