AudioMoth is an output from a research project at the University of Southampton and the University of Oxford to develop low-cost acoustic sensors for environmental and biodiversity monitoring. The hardware design, and all associated software, is open-source and freely available. Note that AudioMoth is a prototype research tool, and is not a commercial product. As such, it comes with no warranty or guarantee that it is fit for purpose.
For more information about the AudioMoth 1.0.0 and device support, please visit the Open Acoustic Devices website.
This Group Buy was created by Alasdair Davies of the Arribada Initiative in response to requests from a large number of individuals all wishing to individually acquire an AudioMoth device. The individual price of devices from CircuitHub varies with their current component stock levels and the number of devices ordered. We have chosen a fixed price to cover this variation in cost and to support users. This cost does not include taxes and duties. This margin will be used to purchase additional AudioMoth devices to be held in a common spares pool and to provide trial devices to interested parties. The Arribada Initiative actively supports both the conservation community and the developers of conservation technology, and is exploring how open tools can help the developers of conservation technologies to distribute, support and maintain the devices they design into the future.

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds. Please see our FAQ page for more details on our billing process.
I have just created the GroupGet for AudioMoth (Round 5)!
Are there any bank charges associated with the payment that we need to take into account? Can you confirm if the money leaves the account at the end of the campaign or straight away as the campaign has already reached its min?
It states end of September for delivery, is there any chance they will be ready by mid-September as this date will change my shipping address?
We will wait to bill until 5 days before expiration. This way anyone with billing issues can correct by the 30 day limit. We want to be able to send funds directly to the mfr ASAP. Not sure what you mean by bank fees - you will be charged what is stated at your checkout. This will probably ship at the end of Sept. Nobody should make big plans based on receiving these on time as the supply chain for the parts for these boards has been challenging at quantity. If your address changes just make a help ticket and we'll sort it.
