SKU: LD-WERKZEUG Categories: , ,


Werkzeug is a USB multi-tool that can be used as a universal programmer, USB-UART bridge, USB-SPI bridge, USB-I2C bridge, USB host bridge, USB-PMOD bridge, programmable GPIO bit-bang device, logic analyzer, debugging tool and a lot more.

Werkzeug is supported by our ldprog software and can be used to program Lone Dynamics FPGA boards and MMODs.

Note: The USB host port capabilities are dependent on open-source software like TinyUSB and Pico-PIO-USB which currently have some limitations. We have successfully tested it with a USB gamepad, your mileage may vary.
