Project 4

WIFI Module

The ESP8266 Wifi module is a complete Wi­Fi network where you can easily connect as a serving Wi- Fi adapter, wireless internet access interface to any microcontroller­ based design on its simple connectivity through Serial Communication or UART interface.

Creating a workspace for WiFi module in altium

Routing:-

Finally, we are getting to the part - routing. it’s always exciting to see rapid progress and a project get closer to completion.

Altium has some fantastic tools that make routing very easy. The Interactive Routing tool is what you’ll most often use for routing. You can get started by pressing Ctrl + W or going to Route → Interactive Routing

Copper Pours (Polygons)

We’re going to add a complete top and bottom copper pour connected to the GND net. This is important for the charger IC's thermal performance, having a copper area to act as a heat sink.

FOLLOWING THE STEP

Thermal relief

Altium PCB design has option to assign the number of thermal spokes as required and has option for the size of the thermal spokes which can also be rotated. Thermal relief can be applied to specific pin specific net or a components. it should be direct connection
