FAQ
Do these RF modules work with Arduino and ESP32?
Yes—LoRa, nRF24L01, 433MHz, and GSM modules all have well-supported Arduino and ESP32 libraries.
What affects wireless range the most?
Antenna type, line of sight, interference, and proper power supply significantly impact range.
Do I need an antenna for my module?
Yes—LoRa, nRF24L01 PA/LNA, GSM, and many 433MHz modules require external antennas for safe operation.
Do you ship nationwide?
Yes—we offer fast shipping anywhere in the Philippines with same-day processing for in-stock items.
