Latest Firmware Releases

Due to supply issues, later T-Series models have a slightly different Real-Time Clock (RTC) chip. Older models therefore require slightly different firmware to support the RTC device.

The model revision can be determined from the devices serial number. Alternatively, check the version number of the existing firmware of your device:

  • Revision B models will have a ‘B’ firmware version postfix. E.g. 2.0.003B.
  • Revision A models will have a ‘A’ firmware version postfix or no postfix. E.g. 2.0.003A or 1.0.004.

Ensure that the downloaded firmware matches your model (T100, T300 or T550) and revision (A or B).

Latest firmware revision: 2.0.003A (rev. A models) and 2.0.003B (rev. B models). Currently all revision B models have the latest firmware.
