The kWeld system supports in-system firmware updates. Besides a computer with a simple terminal program that supports YMODEM file transfers, this requires a serial connection. This set provides the necessary components for this:
1 x USB-to-serial converter (FT232R, 3.3V TTL signals)
1 x connection cable for kWeld system, 75mm
1 x adapter board.
All you need to do is to connect it to your computer with a mini-USB cable (not included), and follow the update procedure in the kWeld operation manual: https://www.keenlab.de/wp-content/uploads/2018/07/kWeld-operation-manual-r3.0.pdf
