ADVANCED PCB

Circuits used for IOT applications require complex processing and stability, capable of storing and processing data on-site. The circuit uses ATMEGA 328 to support device control and combines with Raspberry via UART protocol.

The circuit uses a MEGA2560 microcontroller combined with an input and output expansion IC, reads the OUTPUT signal from the fire alarm panel and then reports it to the phone via wifi using ESP07. It also has a number of expansion ports for later integration, and also has LORA uart to transmit signals to the Led panel for emergency escape instructions.
