Version 4.3.1 of the Opentrons App and OT-2 Software brings a major new feature: the ability to use multiple modules of the same type in a protocol. For instance, you can use two Opentrons Temperature modules in a protocol at the same time. There are also several bug fixes.

Technical change log

Opentrons App

New Features

  • Support for 2 Temperature Modules or 2 Magnetic Modules
  • The USB port to which each module is attached is now displayed in the protocol info screen

Bugfixes

  • Fix an issue where robots would sometimes not reappear after an update when connected via USB (#7608)

OT-2 Software

New Features

  • The OT-2 now supports the use of two Magnetic Modules or two Temperature Modules in the same Python API protocol. See our Help Center article on using modules of the same type for an overview of how this feature should be configured.
  • New API level: 2.10. This API level contains a bugfix for an issue where pipettes would move diagonally when accessing the same well one after another (#7156). The fix is only applied when API Level 2.10 is requested in a protocol to avoid changing the behavior of existing protocols.

Bugfixes

  • Fixes an issue causing slow protocol uploads in protocols using Thermocycler Modules or Temperature Modules (#7506)
  • Fixes an issue where labware could not have a 0 column. You can now once again create custom labware with a column 0 (#7531)
  • Fixes an issue where tip length calibration would not be applied during labware calibration, so calibrating labware would cause incorrect movement during protocol runes (#7765)

Known Issues

In 4.3.0 and previous releases, the OT-2 will only use TLS 1.0 for WPA2 Enterprise association. Some RADIUS servers have disabled this version of TLS; it must be enabled to connect the OT-2 to a RADIUS-secured network.
