No, I'm afraid only the SJ2-35464A-SMT-TR is compatible.

The AudioMoth 3.5mm socket is available in the GroupGets store here.

Hi Nick, AudioMoth 1.2.0 schematics are not available because it is the current hardware version in production. Our general open hardware policy is that when a new iteration of the hardware is developed, the previous version is made available.

1. Yes 2. It will always have a time stamp, but will be inaccurate if the batteries were removed after the clock is set with an AudioMoth app. AudioMoth possesses an inbuilt clock which ticks up every second from a start time. When an AudioMoth is configured using the Chime App, the start time is matched with the smart phone clock. However, when the device loses battery power or is reset, it defaults to the number of seconds since the UNIX epoch (01/01/1970) until it is set. ​

You can only set the time using the Chime App when the switch is in CUSTOM position. When in this position the AudioMoth will listen for the acoustic chime from the AudioMoth Chime smartphone app. While doing this the red light will remain solid whilst the green flashes (100ms). If it doesn't do this the time has already been set. When in DEFAULT mode, AudioMoth will start recording immediately outside of the configured timing schedule, at either the default settings (if the device wasn't configured) or with the previously configured settings. AudioMoth will record one continuous WAV file in DEFAULT mode and will even record if the time hasn't been set. Do you remember where you saw the conflicting instructions? If you send a link we can correct these.

We have recently updated the vents to use the Gore, GAW334 series. These should be available at GroupGets and LabMaker in September 2023.

Hi Sophie, AudioMoth can pick up frequencies up to 192kHz, so 40kHz to 100kHz would be fine. To record at 100kHz you would need to set the sample rate to at least double that frequency, so 250kHz or 384kHz. The first AudioMoth project was actually recording the New forest cicada, who's call frequency is above an adults hearing range.

Hi Carola, Yes we do plan on launching a campaign in about a month or so. If you need them sooner, we will have a small number arriving in the UK soon. Can you email andy@openacousticdevices.info to arrange?

Hi Carlos, AudioMoth 1.2.0 schematics are not available yet because it is the current hardware version in production. Our general open hardware policy is that when a new iteration of the hardware is developed, the previous version is made available.

Hi Maria, Have you been reformatting the SD card to exFAT after making a copy of the data? Deleting files on previously used SD cards doesn't always leave the card in the best state. Thanks, Andy

In post-processing, 5 seconds is the minimum split at the moment. However, you could select 1 second as the 'Minimum trigger duration (s) ' in the AudioMoth Configuration App before deploying.

Hi Caley, Thanks for the message. Instead of selecting the Split AudioMoth WAV Recordings, you'll need to use the Expand AudioMoth T.WAV Recordings function.

The dimensions of the vents are 11x5mm.

Are the files the correct size and readable? If the file sizes are not readable, could you share a screenshot or copy the WAV comments on WAV file 2022034_094500.WAV? In the metadata AudioMoth will state a reason for files ending early.

Replacements for the IPX7 case membranes are available on the GroupGets store. https://store.groupgets.com/products/replacement-acoustic-vent-for-audiomoth-case

If you have updated the firmware beyond the very early version 1.2.1, you can use any size SD card. We are currently on firmware 1.7.1 so that was a long time ago now. SD cards can be formatted to exFat, but should work straight out of the box without needing to re-format. At 32 kHz you could probably use any SD card speed class without any issues, we recommend these SD cards that we have tested for faster sample rates.

I understand your confusion, currently there isn't a way for the Configuration App to read the CONFIG.TXT file off of a device. The device only ever needs configuring once using the Configuration App and will always remember the these settings. Configurations are persistent, even if batteries are removed. The only thing that needs setting after power is lost or batteries run out, is the time. We recommend using the AudioMoth smartphone Chime App after the first Configuration using the AudioMoth Configuration App. The CONFIG.TXT file is only a log file and can be deleted without loosing the configurations set using the AudioMoth Configuration App. AudioMoth will create a new CONFIG.TXT file when the switch is changed from USB/OFF, this is intended for debugging and as a reminder of these original settings. I hope this explains it.

The saved config can be saved manually in the app ‘File’ menu and then loaded onto the app, however, it can’t read the configurations off of a device.

Hi Agus, Yes this is normal. If you want to confirm what was set last on AudioMoth a CONFIG.TXT file is created on the SD card, the file is created when the switch position moves off USB/OFF.

Hi Koen, I'd be surprised if your speaker can vibrate at 100kHz, most are designed to have a frequency response up to 20kHz, unless you have a specialised tweeter speaker. To help find configuration setting for the AudioMoth Configuration App have you seen our new Labs page, specifically the AudioMoth Filter Playground? Here you can upload recordings and experiment with different settings so you can get the perfect filter for your application. Thanks, Andy
