Compact FPGA. Easy Development. Nano-Class Footprint.

KIWI 1K FPGA BOARD

Kiwi 1K FPGA Board is a compact FPGA development board designed for FPGA education, digital logic experiments, IP verification, and small embedded-control applications. The board targets a nano-class footprint compatible with the smallest mechanical size while keeping a practical onboard programming, debug, and I/O expansion experience for rapid prototyping.

Why Choose

Product Positioning

Kiwi 1K is positioned as a small, low-cost, and easy-to-use FPGA board for users who need to learn FPGA design or quickly validate small logic blocks without using a larger evaluation platform. It is suitable for university labs, internal R&D workshops, embedded-control demos, and first-stage FPGA IP verification. Compared with Kiwi 1P5, Kiwi 1K focuses on a smaller nano-class form factor and a more cost-optimized entry point. It keeps the same development-oriented philosophy: onboard programming, simple PC connection, accessible GPIO, and ready-to-run example designs.

Nano-class mechanical footprint

The board has the smallest mechanical size of 58.34 mm x 21.29 mm, making it easy to place in compact demos, breadboard-style fixtures, and education kits.

Ready for quick FPGA development

Onboard USB-JTAG reduces the need for external tools and allows users to program, debug, and monitor the board directly from a PC.

Balanced resources for basic digital design

The 1K FPGA resource class is well suited for FSM, counters, UART, SPI, PWM, GPIO control, encoder/decoder blocks, and small timing-control designs.
