GSM SIM800L Relay Control Shield with Mini Breadboard for Arduino Uno

Nyereka GSM Relay Shield is a unique all-in-one module for Arduino Uno that integrates GSM SIM800L, a relay, a mini breadboard, and a power regulator — making it perfect for IoT projects, remote control systems, and automation. We built this shield to solve common problems that makers face when using GSM SIM800L: Powering it correctly (without damaging the board) Managing relay control for AC appliances Connecting sensors and components easily Removing the need for messy jumper wires Whether you...
