Again, thank you for your quick response. I am trying to compare the two products, the E0 and the B523 for our industrial product, considering the future. Does the B523 have a wake up pin to bring it out of sleep mode? Our product uses the E0 sleep mode. I can get just enough I/O out of the B523 for our product to function on it from a signal perspective, but other than changing the signals (pins) should the software run the same? I don’t want to invest in a whole new software at this time, since I contract out much of our software programming.
We have the software working on the E0 perfectly right now and the software works perfectly with all of our hardware. Our product presently uses the E0, and a BlueGiga Blue tooth module communicating with an Android cell phone app along with a variety of other industrial components. I am thinking about the B523 because it has the cell phone module built in. This could simplify our manufacturing. However the B523 does not have the power management hardware mounted on the module. This would add complexity to our present design.
We developed our product on the Electron module, but we found that in the field, temperatures exceeded the Electron’s max, so we were forced to redesign using the E0 which has a higher top end temperature limit (167 degrees F). We will target the oil well market for the little oil wells scattered around the country, and the hazardous waste industry also.
The E0 module does everything I want it to do, but I really prefer a module that plugs into a connector rather than is soldered to the board. Our industrial product circuit board is not a throw away product. If the E0 fails, that would be a problem.
Our customer is also interested in the Particle Asset Tracker. I see that it uses the same MCU as the B523. On the T523 developer’s board, I see that many pins are not brought out from the MCU on the T523. Are they really not connected? It seems strange that the pin numbers have been brought out to the edge of the T523 module but they are labeled No connection. Why did they go to the trouble to bring these unused pins out to the edge of the module and use the board space to put them there? Could these MCU pins (signals) still be accessed?
Thank you again for your support. I am a serious Particle user. I work in Missouri, but went to Spectra 2018 in San Francisco, and I was working on a mesh product and used the Zenon and Boron modules for that application. That product has been set aside for now.
