Modules

Key Types of PCB Modules

1. By Function:
   • Communication Modules (e.g., Wi-Fi/BT modules like ESP32, Zigbee, LoRa).
   • Sensor Modules (e.g., temperature/humidity sensors, accelerometers).
   • Power Modules (e.g., DC-DC converters, battery management systems).
   • Processing Modules (e.g., microcontroller boards like Arduino, Raspberry Pi).
2. By Integration Level:
   • Standalone Modules – Ready-to-use (e.g., GPS modules).
   • Embedded Modules – Designed for integration into custom PCBs (e.g., System-on-Module, SoM).
3. By Form Factor:
   • Through-Hole Modules (e.g., classic Arduino shields).
   • Surface-Mount (SMD) Modules (e.g., ESP8266 for compact designs).
