Based on the ‘best guess’ the fun part develop end shown in this Instructable follows. Next, with reference to the module, there are 6 quantities labelled at the header/shorting blocks, AHLB, TOG, LPMB, SM, OD and MOT0. ... (TTP224/TTP224N). Working voltage: 2 V to 5.5 V DC Adjustable output mode, key output mode, longest time and fast/low power output PCB board size: 35(mm) x29 (mm). There are three pins, OD, AHLB, and TOG that could be used to configure the output state either high or low or toggle mode enable the option. Skip to main content.in. Perhaps, as a minor sceptic, the plan was changed to include a simple one-LED circuit that would at least confirm the options TOG and MOT did provide off-module results. Isolating the PCB from any workbench debris is the paramount advantage of an under-pad. On PCB, the length of lines from touch pad to IC pin shorter is better. A wide variety of ttp224 switch touch sensor module options are available to you, such as digital sensor, switching transducer. A circuit for testing HIGH/LOW CMOS/OPEN DRAIN is based the single pad approach. The module has 4 touch pads. A quick inventory of pins should show the TTP224 Notes refer to pin numbers as high as 22 but the TTP224 Module probably holds a 16 pin IC. The capacitance Cs0~Cs3 can be used to adjust the sensitivity. First would be a mirror of the item posted at Arduino Learning, essentially ‘out-of-the-bag’ defaults that accompanies no shorting blocks. Provides fast mode and low power mode selection by pad optional (LPMB pin). The greatest difference is the addition of the LED and supporting SMD resistor network but it doesn't take more than a cursory point by point comparison to concluded the module's options cannot be all those promised in the application note. The IC uses an onboard sense pad that uses copper trace as a touch element and the touch sensitivity can be configured using an additional external capacitor ranging from 0 to 50pF. Provides direct mode or toggle mode, CMOS output, or open-drain output. Although it would be 'nice' to claim there was some test-based purpose, there is not. 4 key board TTP224 capacitive touch sensor IC Onboard 4-level status indicator. Other optional can be taken to be ‘preferences’. About 6% of these are sensors, 3% are integrated circuits. 2.

The C1 can be configurable as per the required sensitivity. On board TTP224 capacitive touch sensor IC 4 keys; 4 board-level status indicator; Working voltage: 2.4V-5.5V; The module can set the output mode, the key output mode, the maximum Output time and fast / low power selection; PCB board size: 35 (mm) x29 (mm) On first consideration, this seemed to also be suitable for the CMOS active low option but the first attempts with that configuration caused a power spasm at the UNO. Finally, without the VREG pin of course there is no option and whether the voltage regulator is enabled or disabled or even exits can be left out of this Instructable. The design/layout of the module seems to parallel the off-the-rack application note. The final assumption was that the shorting block options were used to ‘configure’ the TTP224 at power-on. With the optional electrician tape and corkboard, an under-pad for the module can be created. 3. The first inclination is to accept that approach and rather than struggle with wording simply refer to Julian Ilett's video. Direct mode and Toggle mode selection pin available. Hopefully this rather lengthy Instructable contain information useful to someone and wishfully prompt someone to contribute their knowledge and skills to the question of design. Stable sensing method can cover diversity conditions. Whether the options can be clearly invoked and their ‘functionality’ is important, not the PCB design.
