SIM800L is a miniature cellular module which allows for GPRS transmission, sending and receiving SMS and making and receiving voice calls. Low cost and small footprint and quad band frequency support make this module perfect solution for any project that require long range connectivity. After connecting power module boots up, searches for cellular network and login automatically. On board LED displays connection state (no network coverage – fast blinking, logged in – slow blinking).
Be prepared to handle huge power consumption with peek up to 2A. Maximum voltage on UART in this module is 2.8V. Higher voltage will kill the module
The SIM900A GSM GPRS Wireless Extension Module is a versatile communication module designed for SMS, voice calls, and GPRS data transmission. It supports quad-band frequencies, making it ideal for IoT projects, remote monitoring, and wireless communication applications. With its compact design, onboard antenna, and easy integration, it’s perfect for Arduino, Raspberry Pi, and microcontroller-based projects.
The 2-Channel Solid State Relay (SSR) Module is a high-performance switching device designed for fast, noise-free, and reliable AC load control. It operates silently with no mechanical wear, making it ideal for home automation, industrial applications, and microcontroller-based projects. Compatible with Arduino, Raspberry Pi, and other controllers, it ensures safe and efficient switching of electrical devices.
Ublox NEO-6M GPS Module with active Antenna is a cost effective, high-performance u-blox 6 based NEO-6 series of GPS modules, that brings the high performance of the u-blox 6 positioning engine to the miniature NEO form factor.
These receivers combine a high level of integration capability with flexible connectivity options in a small package. This makes them perfectly suited for mass-market end products with strict size and cost requirements.
Key Features:
Applications:
ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.
