SPIDER Automation THEJAS32 RISC-V SoC Development Board | VEGA ET1031 Processor
Description
SPIDER Automation THEJAS32 SoC-Based Microprocessor Development Board is built around the VEGA ET1031, a compact, efficient 3-stage in-order 32-bit RISC-V processor core. Engineered for low-power IoT domains, industrial monitoring, and academic research, this system-on-chip combines a Harvard architecture with low interrupt latency and vectored interrupt support to deliver reliable real-time performance.
The board packs a robust set of onboard peripherals—including multiple UART, SPI, and I2C channels, PWM outputs, analog-to-digital converter channels, and 32 versatile GPIO pins. With a clock frequency scaling up to 100 MHz and 3.3V I/O compatibility, THEJAS32 provides engineers, students, and makers with an accessible indigenous platform to explore open-source RISC-V architecture and build custom embedded applications.
