A wifi 2.4ghzembedded product development router pcb board is a printed circuit board (PCB) that is used to support Wi-Fi 2.4GHz wireless communication functions in an embedded system. This PCB board integrates a processor, memory, transceiver, and sometimes an antenna to convert serial or TTL levels to an embedded module.
Wifi 2.4ghzembedded product development router pcb board components
2.4 GHz WiFi: Refers to a wireless communication standard that operates in the 2.4 GHz frequency range and is widely used in home and office networks for its wide coverage and ability to penetrate walls.
Embedded Product Development: Refers to the design of electronic systems that are integrated into larger products, such as household appliances, industrial equipment or IoT devices.
Router PCB: The printed circuit board (PCB) is the physical foundation of a router, carrying all electronic components and providing the necessary connections.
Key Design Factors
When designing a PCB for a Wi-Fi 2.4GHz embedded product, a number of factors need to be considered.
Component selection: Choosing the right microcontroller (MCU), RF chipset, power amplifier (PA) and low noise amplifier (LNA) is critical. Commonly used Wi-Fi chipsets include Cypress CYW4343W, Microchip ATWILC3000, Texas Instruments WL183x and Realtek RTL8723DS.
PCB Layout: Optimised component layout minimises alignment length and reduces noise coupling. Group related subcircuits together and keep RF alignments short and straight.
RF alignment design: RF alignments need to be impedance controlled, typically 50Ω or 100Ω, to match the impedance of the chipset to the connector or antenna to maximise signal power transfer. 90° bends should be avoided and 45° alignments used to minimise signal reflections.
Grounding: A continuous ground plane is critical to provide a low impedance reference. Use multiple vias to connect ground pads and connect analogue and digital ground at a single point.
Power filtering: Add ferrite beads, capacitors, and π-filters to the power lines to prevent noise coupling.
