FAQ
ESP32 vs ESP8266 — which should I choose?
ESP32 adds BLE, more GPIO, faster cores, and better peripherals. Use ESP8266 for ultra-budget Wi-Fi nodes.
Can I program this with the Arduino IDE?
Yes. Install the ESP32/ESP8266 board packages. MicroPython is also supported on many boards.
Any power tips?
Size your 5V/3.3V supply for Wi-Fi spikes (≥700 mA headroom). For battery, use LiPo + charger/boost and enable deep sleep.
Do you ship nationwide?
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
