This chapter introduces the key points of how to design an ESP32-C6 PCB layout using the
ESP32-C6-WROOM-1 module as an example.

3.1 General Principles of PCB Layout

It is recommended to use a four-layer PCB design:
• Layer 1 (TOP): Signal traces and components
• Layer 2 (GND): No signal traces here to ensure a complete GND plane
• Layer 3 (POWER): GND plane should be applied to better isolate the RF and crystal. Route power traces
and a few signal traces on this layer, provided that there is a complete GND plane under the RF and crystal.
• Layer 4 (BOTTOM): Route power traces here. It is not recommended to place any components on this layer.
A two-layer PCB design can also be used:
• Layer 1 (TOP): Signal traces and components
• Layer 2 (BOTTOM): Do not place any components on this layer and keep traces to a minimum. Please
make sure there is a complete GND plane for the chip, RF and crystal.
