Absolutely! Let's assume you'll be using GPIO5 to control the relay, specifically the relay module that you have labeled as K1. Here's how you can connect the relay to the ESP32 to switch mains power.
I am assuming the relay operates with 3.3V for the control signal since you are using an ESP32, which operates on 3.3V logic levels.
Connections
Relay Control Signal:
Connect ESP32_C3:IO5 to K1:1 (Assuming K1:1 is the control pin for the relay).
Relay Power Supply:
Connect a 5V power supply (which should be suitable for your relay if it's a typical relay module) to K1:2 (VCC).
Relay Ground:
Connect GND to K1:3 (GND).
Relay Common and Normally Open/Closed Contacts:
Connect the common terminal (usually labeled COM or C) of the relay to the load (e.g., appliance).
Connect the Normally Open (NO) or Normally Closed (NC) terminal to either the mains live wire or the neutral, depending on how you want to control the switching.
Connection Format
Here's the specific connection format:
Control Pin: Connect U1:IO5 to K1:1.
Power Supply (assuming VCC 5V): Connect VCC 5V:P1 to K1:2.
Ground: Connect GND to K1:3.

Plaintext
ESP32 -----> K1
VDD 3V3 | | // power
| | // control signal
GND |------| // ground
| |
IO5 ------|-> IN | // control signal from ESP32
// Connect ESP32 U1:IO5 to K1:1 for control
// Connect VCC 5V:P1 to K1:2 for power
// Connect GND to K1:3 for ground
Please make sure to double-check your relay module's datasheet to confirm the correct pins for power, ground, and control.
Would you like me to generate a more detailed explanation or any other connections you might need?
