QWERTY Embedded Design has introduced a easy add-on for the FPGA developer trying to put a few low-power Arm Cortex-M0+ cores and programmable enter/output (PIO) capabilities into their initiatives: the RP2040-PMOD, which places a Raspberry Pi RP2040 microcontroller on a PMOD board.
“This merchandise is an easy RP2040 MCU [Microcontroller Unit]-based [with a] twelve-pin connector that was constructed to permit FPGA customers to have a versatile communication system for debug and IO [Input/Output] growth,” the corporate explains of the compact board. “It might present UART, SPI, USB, analog or GPIO [General-Purpose Input/Output] interfaces to an FPGA.”
The PMOD normal was developed to make it straightforward to construct growth {hardware} for FPGA growth boards. On this case, it serves to host the Raspberry Pi RP2040 microcontroller — giving it a pair of Arm Cortex-M0+ cores operating at a inventory 133MHz and 264kB of static RAM, plus a sensible programmable enter/output (PIO) block able to operating state machines independently of the 2 processor cores.

Whereas suitable with any FPGA growth board which might settle for PMOD add-ons, QWERTY recommends the system as an adjunct for its personal ICE-V Wi-fi, launched final 12 months as a low-cost open-hardware board combining an Espressif ESP32-C3 RISC-V system-on-chip with a Lattice Semi iCE40 UltraPlus FPGA — and together with, in fact, numerous PMOD headers.
The RP2040-PMOD is now funding on GroupGets, priced at $20 plus transport per board; the marketing campaign is because of shut on December seventeenth with {hardware} to ship 42 days after. Design recordsdata for the board can be found on GitHub below the permissive MIT license.
