Based on the idea of ch2i, but complete rework.
This PCB is used to connect Raspberry PI and ISMT iC880A LoraWan concentrator Gateway (SPI version) togehter and to be able to put the whole thing into a outdoor enclosure. Power can be supplied via passive or active PoE adapters.
- highvoltage power regulator for passive PoE -48V usage based on LM2576
- optional use DC/DC module for active PoE adapters with +12V output
- BME280 header for temperature & humidity measurement within the housing, optional BMP280
- DS18S20 Header for outside & inside/case sensor
- added GPS module for time & PPS sync
- optional +3V3 -> +5V TTL serial converter, could be used for other sensors like SDS011 dust particle sensor
- LC filters on power supply rails
- LED for GPS PPS and signal routed to GPIO25
- DS1307 RTC hardware clock for Raspberry + Battery
