Smart Citizen PM Board

The PM Sensor Board is an auxiliary board capable of driving a wide variety of connections. It is mainly intended to serve as an I2C bridge between the Data Board and several types of sensors, as well as to provide an off-the-shelf connection to the Plantower PMS5003 sensors supporting JST-XH connectors. The board runs a dedicated ARM M0+ 32-bits, the same as to the Data Board to provide a unified hardware architecture. The board includes a step up to provide 5V to drive the PM sensors and a disable/enable circuit to turn off the sensor by software. Finally, this board includes a standard set of Grove Connectors, including I2C bridge, 12bit ADC, GPIO and UART interfaces, for auxiliary sensors such as external temperature probes or anemometers.
