I misspoke on the DC/DC supply. It is a Meanwell DDR-15G-5. Pic of the guts on that polycase is attached.

We use a polycase 12x10x6 customized enclosure for under $85 with everything predrilled https://www.polycase.com/yh-121006.

We made a custom din rail bracket to hold the two batteries. 10W panel for solar but charger will accommodate up to 30W

12V to 5V is a DC/DC Din Rail supply P/N: MDR-20-5. The board takes in 5V and and has a 3.3V LDO onboard for those 3.3V parts that pull more than the teensy 3.3V output can provide.

@neilh,

Yes, we have solar to the charger and into (2)12V 9aH batteries (in parallel). The Teensy and Xbee are on a custom motherboard we designed. Has lots of the IO broken out and spots for Adafruit GPS, RTC battery, ESP32 (older requirement) and Wiz850io Ethernet.

Teensy 3.5 topic set up.

@Both

google drive link for the XBee files if either one of you want them in the future.

Are these Verizon Jetpacks with Wifi or do your modems have a serial connection? We started out with AWS, Verizon Jetpacks w/WiFi and the ESP32. It worked, we just didn’t have an active AWS contract in place so the free trial accounts were running out of room for us. We at that point just set up an internal MQTT Broker so we (National Weather Service) didn’t have to pay anything for the service.

@dan

I agree with @neilh in that AWS can be a little cumbersome. I have used it with the ESP32 platforms in the past via WiFi, but in the end opted for using other end points than AWS. Lots of free dashboards out there for starting out and learning. Most of the really nice ones start adding costs once you decide to scale up the number of data points and devices, but still great for getting off the ground to you hone in what you are trying to achieve..

What were you planning on using for your network transmission device (cell modem, XBee, ESP)???
