: SPI data transmission line from MCU to radio. Pass-through to the radio.
Furthermore, standard microcontrollers (like the Arduino Uno or Nano) often feature low-current onboard 3.3V regulators that cap out at 50mA or 150mA. High-power wireless transmissions—especially when using an nRF24L01+ with Power Amplifier and Low Noise Amplifier (PA+LNA) hardware —experience large instant current spikes (often exceeding 115mA). These spikes cause voltage drops, resulting in broken SPI connections, data corruption, or transmission drops.

The YL-105 handles these issues directly by decoupling the transceiver power rail through the dedicated AMS1117 regulator. It also includes dual SMD filtering capacitors located near the inputs and outputs to smooth out rapid transceived power transitions.
