This user guide provides information on the ESP-LyraP-TouchA extension board. This board cannot be bought separately and is usually sold together with other Espressif development boards (e.g., ESP32-S2-Kaluga-1), which will be referred to as *main boards* below.
|
||
|
|
|
||
|
|
The ESP-LyraP-TouchA extends the functionality of your main board by adding touch buttons.

* - Key Component
|

|
|
- Description
|
||
|
|
* - Main Board Touch FPC Connector
|
||
|
|
- Connect to main board's Touch FPC Connector.
|
||
|
|
* - Touchpad
|
||
|
|
- Capacitive touch electrode.
|
||
|
|
* - Guard Ring
|
||
|
|
- Connected to a touch sensor, the guard ring triggers an interrupt if wet (Water rejection). It indicates that the sensor array is also wet and most (if not all) touchpads are unusable due to the false detection of touches. After receiving this interrupt, the user might consider disabling all the touch sensors via software.
