Wow…impressive board and impressive work.
Two features that drew my attention:
Nimblelink cellular socket
Nimblelink cellular socket:
We have looked at using Nimblelink cellular LTE modems, but we have so much invested in the driver we developed for the Multitech MTSMC-LVW3. This driver/cell modem combo provides very high connectivity reliability.
Not questioning if Nimblelink is better or worse (I don’t know), just wondering what decision path was walked to choose Nimblelink over other vendor(s) wares?
We have been using a Sealed Rechargeable Lead Acid battery for our battery backup.
The battery goes from a high heat to nominally cold environment. With such, battery replacements are common.
We have shallowly looked at using SuperCap(s), but yet to go down that path.
How many amp-hours do you figure your SuperCap setup can provide?
Our BBU only needs to provide enough voltage & current to power the SOM, cell modem and other low-draw circuitry, for say 30s (connectivity good) to 2min (connectivity bad)…our devices are deployed in the hinterlands, so level of cell tower signal strength and connectivity ranges.
