LoRa Remote Alarm Transceiver
My latest, and hopefully last LoRa based project for a while... In this one, I basically replaced the logic converters with a dedicated chip, as well as added a buzzer output as well. The idea was that a person could have one of these as a mobile unit, and a few others at fixed places... with a different alarm tone for each location... I also decided to finalise the design in a relatively small 66mm x 77mm PCB, capable of being powered from 12v DC. As usual, the manufactured PCB is done to a high quality standard, and free of defects :) Thank you
