“Grasshopper v0”

This is the initial version of the Grasshopper USB-to-RS232 adapter. It had been assembled to support the chip flasher project, as readily available adapters often fail to work reliable.

The Grasshopper device development will be made available as a free-design hardware project, in future. For now, this webpage serves as a first reference point, which is used by the chip flasher’s README.

See Grasshopper, first Prototype from 2025 in the shop for some details.
