2 Schematic Checklist
ESP32-S3 also integrates a USB Serial/JTAG controller that supports USB 2.0 full-speed device.
2.10 Touch Sensor
When using the touch function, it is recommended to populate a zero-ohm series resistor at the chip side to
reduce the coupling noise and interference on the line, and to strengthen the ESD protection. The recommended
resistance is from 470 Ω to 2 kΩ, preferably 510 Ω. The specific value also depends on the actual test results of
the product.
The ESP32-S3 touch sensor has a waterproof design and digital filtering function. Note that only GPIO14
(TOUCH14) can drive the shield electrode.
