Update your Module

Attention: When updating the firmware, all patterns and settings will be overwritten!

To transfer a firmware update you need a computer with a serial USB interface. Since the heart of the sequencer is an ATMega328, especially an Arduino UNO is excellent. But it also work with standard interfaces such as FT232 or similar.

You also need the transfer program AVRDude which comes with the Arduino software. AVRDude is a command line utility. But there are also graphical interfaces, for example HexUploader (MacOS) or Xloader (Windows).

The Update folder contains the firmware hex files which you can transfer to the device.

Select the version you want to transfer. Connect your Robaux SWT16+ to your serial port as shown in the pictures.

Select your serial interface in AVRDude or a corresponding program as well as the HEX file and transfer it to the Robaux SWT16+. If you have any questions, please contact
