Soan Papdi FPGA
A dev board that makes learning FPGA development easy.
Most FPGA boards assume you already know what you're doing.
Soan Papdi doesn't.
Built for beginners, it comes with onboard LEDs, switches, and GPIO headers, so you can focus on learning FPGA instead of setting up hardware.
⚡No complex HDL needed
Program it using the open-source iCEStudio IDE.
Just connect the blocks, and deploy your digital circuits directly to the FPGA.
Specifications
(capable of hosting RISC-V)
- • 8 × Yellow 3.0 mm through-hole LEDs (D7–D0)
- • 4 × White 0603 SMD status LEDs (S3–S0)
- • 8 × DIP switches with orange indicator LEDs
- • 2 × Push buttons (Program & Reset)
- • 10 × GPIO pins for external sensors & peripherals
Supported Toolchains
iCE Studio, APIO, Yosys, nextpnr, IceStorm, Icarus Verilog, Amaranth HDL.
Designed for Learning
Output LEDs
8-bit data is very common, things like counters or state machines, you can directly see the output on these LEDs.
Status LEDs
Signals like carry flags, overflow indicators can be shown here.
Input Switches
Using these switches, you can input two 4-bit numbers into your circuit. Now you can add, subtract & instantly see the result on the LEDs.
GPIO Headers
These headers let you connect external components like sensors, displays, motors, or your own custom hardware to extend the capabilities of Soan Papdi.

Learning Resources
To make things easier, Piyush has created a Digital Electronics 101 course, where everything is explained step by step.
You can explore built-in examples and learn by doing.
Start simple — build basic gates like AND, OR, or a decoder.
Once you’re comfortable with the basics, move on to these advanced projects:
- RISC-V CPU— Build and run a RISC-V processor on your FPGA.
- Z80 CPU— Recreate the classic Z80 microprocessor using open-source FPGA tools.
- Hack CPU— Implement the Nand2Tetris Hack CPU, built gate by gate.
The Team
Proposal of Soan Papdi was made by Piyush, the idea was brought to life by Hardik & Lakshya.
