Just starting a discussion on the new Mayfly 1.0 compatibility.
Seems like, the core interfaces and using Digi LTE CAT-M1 should be compatible, (possibly requiring the LTE Adapter board)
providing the following port bits on Mayfly 0.5b Digital Header J4 (now H2 on Mayfly1.0) are not used.
D12 (now 12V_Sw) D23 (now V_BATT)
D20 (now X3) D21 (now X4)
D18 (now X1) D19 (now X2)
and analog Header J3 (now H1)
A7 (now 12V_SW) and (now A7 shifted to H1 Pin 17)
A5 (now A7) and Mayfly1.0 A5 now drives Xbee RESET
With Bee Socket there are some changes, however the core compatibility with signals to a Digi LTE CAT-M1 should work.
IHMO seems like with the LTE Adapter board it should work, providing LTE_RST is not used
Without the new LTE adapter, the Mayfly signal A5 needs to be checked, it needs to be left open or pulled high, or designated as Xbee RESET.
Seems to me that pulsed currents from the LTE boards may be a cause for some concern https://github.com/EnviroDIY/EnviroDIY_Mayfly_Logger/issues/31
I am only referencing the Digi LTE CAT-M1 as a reference as that is part of my test setup.
The Digi LTE CAT-M1 isn’t currently available and I haven’t seen any dates on when it might become available.
The new EnviroDIY LTE Bee seems like it is in the works both availability and software testing.

I have a couple of related questions as we prepare to integrate v1.0 boards into our new deployments, while also keeping our existing 0.5b installations operating for as long as possible.
- Will Hologram SIMs work with the new EnviroDIY LTE Bee modem? I recall seeing a discussion that it was under test, but can’t seem to find that now.
- Will the new EnviroDIY LTE Bee modem work with Mayfly 0.5b (provided that the EnviroDIY LTEBee Adapter board is also used)?
- Will the Digi LTE CAT M-1 work with Mayfly v1.0? I’m assuming so, based on the Mayfly’s Details and Specs page.
Thanks! Excited to try the new boards.

The same Hologram SIM cards we’ve been using for the past year in the Digi boards work just fine in the new EnviroDIY LTE boards.
The new EnviroDIY LTE bee works in the old Mayfly 0.5b boards, and no LTEbee adapter is needed. The LTEbee adapter is only needed when using Digi boards with Mayfly 0.5b boards.
Digi LTE CAT M1 boards work directly with the Mayfly v1.0 board with no LTEbee adapter needed anymore. I added new solder jumpers on the back of the new Mayfly (SJ16, SJ17, SJ19, SJ20, & SJ21) to allow users to make the necessary changes to pin connections to account for the difference between the Digi line of Xbee products and other bee-footprint devices. I’m in the process of writing all of these procedures up, but shifted our focus to getting all the products prepped and available in our shop and on Amazon recently because of all the requests to purchase even before the documentation was finished.
I’ve added the Eagle board and schematic files to Github and will be adding various code example sketches for the new Mayfly v1.0 in the next day or so.
