$ 1.26
- Description TTP229 16 KEY CAPACITIVE TOUCH KEYPAD MODULE IN PAKISTAN TTP229 Capacitive Touch Module is can replace conventional 4×4 keypad with a touch based keypad. The module has two working modes. A 8 key mode that provides a independent 8 channel output or a 16 key mode that can be used with the I2C interface of the module, there by saving even more pins and connections on the application Arduino or Microcontroller board.Sensitivity can be adjusted by the capacitance(1~50pF) outside. Onboard TTP229 capacitive touch sensing IC 16 Keys Onboard power indicator Working voltage: 2.4V-5.5V Module can set output mode : key output mode, output time, low power choice Color: Blue Weight: 5g Dimensions: 65 x 50mm Built-in regulator with external enable / disable option Operating current at VDD=3V no load, low power mode = 2.5uA, fast mode = 9.0uA response time 100mS in fast mode and 200mS in low power mode TTP224 response time 60mS in fast mode and 160mS in low power mode TTP224N Sensitivity can be adjusted by capacitance (0~50pF) for each touch pad Fast mode and Low Power mode selection by pad option (LPMB pin) Active high or active low by pad option (TOG/OD/AHLB pin). 2 output pins TPQ0D and TPQ2D that have no diode protection, active low maximum on time 120sec or 64sec or 16sec or infinite by pad option (MOT1, MOT0 pin)
