Flasher Portable PLUS is the handheld stand-alone Flash Programmer for microcontrollers with on-chip and external flash memory. It is battery driven, designed to meet the need for an extremely portable, production-grade flash programmer for in-field firmware updates.
Flasher Portable PLUS can be powered by its internal rechargeable battery or USB. It has an integrated display for reviewing firmware and programming status.
Initial setup/preparation for stand-alone mode operation is done via the same J-Flash software used by other Flasher models and runs on Windows, Linux and macOS.
Flasher Portable PLUS allows up to 16 configurations/image files to be stored on the Flasher, so one unit can be used for different targets, versions or configurations. Proper image selection is done by simply clicking a button. The currently selected image is displayed.
Isolators to electronically isolate (galvanic isolation) the Flasher Portable PLUS from the power supply or the target, and adapters for all common connectors, are available for the Flasher Portable PLUS. Each Flasher includes the licenses to program all supported MCUs.
