1. All touch PDD200A101 can share the output of a single Guard. MTouch will sense in sequential scanning mode. So when Guard actively drives protection, the touch sensor will not affect other sensors while scanning.
2. Properly lay the upper and lower ground grids in unused areas, and increase grouting holes to reduce mutual impedance and achieve optimal anti-interference ability.
3. On the front of the PCB layout: The size of the touch sensing point (Pad) is not recommended to be less than 5mm in diameter, and the ideal layout for touch points should be greater than 10mm in diameter.
4. On the front of the PDD200A101 layout: The width of the Guard circular line around the touch sensing point should be about 0.3~1.5mm, and there should be a distance of about 0.3~2mm from the touch sensing point.

5. On the back of the PCB layout: The PCB wiring from the touch sensor to the MCU is also important, and it is recommended to use a line width of 0.15mm to 1.2mm. The distance between the Guard Line and the touch PDD200A101  can be as small as 0.4mm, and it is best to add Guard protection on the back in the shape of a Pad (such as the Tx layout on the back of the red PCB).
To reduce high-frequency noise interference from the sensing point, a 10K (recommended value) resistor must be connected in series before the sensor cable enters the MCU pin.
The biggest function of this resistor is: 1 Protect the input pins of the sensor to avoid damage to ESD.
Forming a low-pass filter with the internal capacitor can filter out high-frequency noise (the filtering capacitor should be as close to the MCU pin as possible to achieve a larger filtering effect).
