Modular Soan Papdi FPGA Demo
A Soan Papdi FPGA board demo showed modular hardware connections enabling real-world I/O beyond simulation — a practical example of hardware modularity for prototyping sensors and actuators, shared. The clip underscores how modular FPGA platforms speed integration testing for embedded control projects.
Hardik Seth published an iCE Studio block-based walkthrough for Soan Papdi on YouTube, demonstrating the board’s visual programming flow and upload process. youtube.com Soan Papdi is built around the Lattice iCE40UP5K FPGA with 5,280 LUTs and 120 Kbit embedded block RAM, plus 1 Mbit SPRAM and 8 DSP multiplier blocks listed in the product spec sheet. pages.razorpay.com The board ships with 128 Mbit onboard Flash and a DFU bootloader, and uses a USB‑C interface that is “fully controlled by the FPGA (no ext. MCU)” according to the project page. pages.razorpay.com Toolchain support includes open-source flows—Yosys, nextpnr and IceStorm—and the demo highlights iCE Studio block workflows that let users build logic graphically without HDL. pages.razorpay.com Hardware I/O on the board is deliberately minimal and learner-friendly: 10 general-purpose I/O pins for external sensors/peripherals, 8 through‑hole status LEDs and 8 DIP switches for inputs, details shown in the walkthrough and spec pages. pyjamacafe.com Soan Papdi’s creators list Hardik Seth and Piyush Itankar as collaborators, the board is available for preorder at ₹5,000 with a stated shipping window of 15–20 working days, and the project publishes tutorials and CAD/models for follow‑along learning. pages.razorpay.com
