Hello Shannon/@shicks – thanks for the detail.I missed that it was an internal connection on the mega1284 to the 3.3V
The issue with the 3.3V, is that it is connected to the LiIon through the regulator SPX3819.
The regulator has a dropout that is variable depending on the load, temperature etc – so from the datasheet at load of 500mA it could be…[Read more]
The AREF pin of the micro on the Mayfly is not tied to anything (except through a capacitor to ground as suggested in the ATmega datasheet), so when you use the standard analogRead(0) command, it uses the default 3.3v reference setting. If a user is more advanced and wants to use an internal reference by using certain commands, or by connecting…[Read more]
Just wondering if AREF connects to a voltage source.? Looking at the rev0.5B and IC1 pin 29 labeled AREF I can’t find how AREF connects to 3.3V – but its probably I’m missing something. If it was an annotated PDF I could search for AREF.
The code suggests AREF is connected to 3.3V.
If it does connect to 3.3V, can it be disconnected, leaving C19…[Read more]
I’ve spent more time fiddling with the LTE-M XBee and I’m seeing the same results.
It’s a hardware problem, not software; the modem really does stop responding. I wonder if it’s that there’s not enough capacitance along the power line causing very short voltage drops even when it’s tied right to the battery. The user guide for the LTE-M XBee…[Read more]
I’ve made an Arduino library for communicating with the Yosemitech sensors: https://github.com/EnviroDIY/YosemitechModbus
It’s built on top of my modbus library: https://github.com/EnviroDIY/SensorModbusMaster
In the modbus library there’s a hardware folder with the plans for a little “wing” board to more easily connect a Yosemitech sensor to…[Read more]
Hi Thomas and anthony,
I know it has been long since the post was discussed but by any chance did you guys move along with the project and made any breakthroughs? It would really help me alot.

Oh dear. That definitely *is* a problem. And that’s entirely my fault; I hadn’t error-checked that json in a long time. It should be fixed now.
Just FYI, there’s a lot in that library bundle.

Following the instructions at https://github.com/EnviroDIY/Libraries, I’m entering the following command into a VSCode/PlatformIO terminal: pio lib -g install https://github.com/EnviroDIY/Libraries.git#platformio.
I get this result: “Error: Could not load broken JSON: C:UsersDave’s…[Read more]
I’ve usually seen that “no response” pattern with the 3G XBee’s without the solder jumper. I’ve assumed it was them “browning out” as they tried to connect to the internet. With those, switching the solder jumper seemed to fix the problem. Have you been able to connect to the internet at all with the LTE-M XBee? Is it working attached to a…[Read more]
We’ve bought these ones from Oregon Rule: https://oregonrule.com/product/superior-staff-gauges/ They don’t rust like the WaterMark ones eventually do. And, at least in the US, they’re cheaper.
