Quick spec callouts - what to pick
Use these selection prompts to match a module to your project requirements:
- Range & throughput: ESP32 (dual-core, higher throughput, BLE + WiFi) for streaming or multi-sensor nodes; ESP8266 for single-sensor WiFi links.
- Form factor: choose module (e.g., ESP-WROOM style) for compactness, or development boards (e.g., NodeMCU/DevKit) for breadboard-friendly prototyping.
- Power budget: ESP32 draws more current during WiFi transmission - confirm your battery or regulator can handle peak draw.
