SKU: LD-DOPPELMUSLI Categories: , , ,


Connect a keyboard, mouse, flash drive or other USB device to your FPGA development board or any system with a 12-pin Pmod™ compatible socket.

Doppelmüsli has two modes:

  • Pmod™ compatible USB device bridge + USB host bridge
  • Pmod™ compatible Dual USB host bridge

Doppelmüsli provides a Pmod™ compatible interface to a Raspberry Pi RP2040 MCU. In host mode the 5V USB VBUS power is supplied by a step-up boost converter. The second USB host port is made possible thanks to the Pico-PIO-USB project.

Note: Doppelmüsli must be powered by the Pmod™ connector while Müsli supports a stand-alone USB-powered device mode.
