“Does what it says it does. It's worth noting, however, that the RX/TX pins are NOT the RX/TX pins coming off of the PMS5003, but where you should connect to on your microcontroller (basically, flipped from the sensor pinouts). Took me a good while to figure that out.”
“I've had some PMS5003 sensors for quite a while, but the cables they come with have very small connectors/headers and this board allows connecting to standard parts using standard fly leads etc. Perfect for connecting to Arduino, Raspberry Pi, Beagleboards etc”
