The WLE900V5-27ESD 8AB requires a dual-rail power supply (3.3V for core logic and 5V for power amplifiers) to achieve full transmit power. The miniPCIe interface includes dedicated pins for both voltage rails (pins 2, 24, 39, 41, 52 for +3.3V; pins 45, 47, 49, 51 for +5V). Ensure your host system provides these voltages to avoid reduced performance.
