The first PCB has been designed and is being sent off for a prototype run. Soon, the first batch of 25 will arrive! The purpose of this board is to make it very easy to add Atlas Scientific equipment to an Arduino. The board has spots for 6 different devices. One is a dedicated spot for the dissolved oxygen sensor. The other 5 spots are available for any combination of PH, ORP and Salinity sensors you desire. Mix and match them to create the best sensor array for your needs. We choose a standard BNC footprint design that offers the best durability and flexibility. It is best to choose a BNC connector that is completely shielded. However, this is not a requirement. Another great feature is the 8 port MUX/DEMUX chip. This ensures that you can add more boards by daisy chaining them together while still using only one serial port on the Arduino. (That is if you need more than the 6 sensor slots available on the single board.) Last, we went with a standard pin configuration so you can choose your own connector for wiring this board to the Arduino. One of the best choices, in my opinion, would be a clip style Molex connector. The next PCB on the list is a redesigned super sleek controllable power strip. Stay tuned for that and more!
