The SIM800A Quad-Band GSM/GPRS Module with RS232 Interface is a complete Quad-band GSM/GPRS solution in an LGA(Land grid array)

These are Carbon Film Resistor with a value of 75k ohm 1/2W and tolerance of ±5%

and safe operating area protection which makes them virtually immune to damage from output overloads

4 Channel 5V Solid State Relay Module 300K heating regulationThe Solid State Relay (SSR) offers many advantages over the classic mechanical relay: it has a longer life, a considerably faster switch on off speed, and no noise. It also has better vibration and mechanical shock resistance, as well as better moisture resistance. This Solid State Relay Module includes four channels, each of which may work independently and be controlled. It is based on the Omron G3MB and is capable of controlling current up to
