Troubleshooting E-stop button issues with FarmBot Express v1.0 kits

It has come to our attention that a hardware bug with FarmBot Express and Express XL v1.0 kits is preventing the E-stop button from working. Over the last few weeks we investigated potential software fixes but have been unable to remedy the issue with software alone. Luckily, there is a quick hardware fix that can be applied, as outlined in this troubleshooting documentation. If any of our Express kit owners continue to have issues with this, please let us know here in the comments or get in touch at

We regret that this bug made it into our production electronics boards, especially for something as critical as the E-stop button. We’ll be sure to fix this issue in future versions of the kit.
