Important Notes for Design
Power Supply Design: To achieve maximum output power, a stable 5V power source capable of delivering high peak current must be connected to the VCCPA pins. The core VCC must be supplied separately per specifications.
Antenna Selection: Communication range is highly dependent on antenna performance. Always use a well-matched and efficient antenna tuned for the operating frequency band.
Thermal Management: The module may dissipate significant heat during high-power transmission. Proper thermal design should be considered for enclosed spaces or high ambient temperature operation.
