FAQ
Can I use these IoT modules with Arduino?
Yes—ESP8266, ESP32, LoRa, and GSM modules are easily integrated with Arduino and PlatformIO.
Which module is best for long range?
LoRa provides the longest range (hundreds of meters to kilometers depending on conditions).
Will GSM/LTE modules work without WiFi?
Yes, they use cellular networks—great for remote areas or SMS-based control.
Is ESP32 better than ESP8266?
ESP32 is faster, has BLE, more I/O, and better performance—but ESP8266 is cheaper and still excellent.
Do you ship IoT modules nationwide?
Yes—fast shipping anywhere in the Philippines for all IoT modules and accessories.
