Featuring Ethernet, MIPI CSI/DSI interfaces, and GPIO pin headers, the board is designed for developers eager to explore Espressif’s latest innovation.
Bulgarian open hardware company Olimex has launched its new ESP32-P4-DevKit, a compact development board featuring Espressif’s dual-core 400MHz RISC-V ESP32-P4 system-on-chip. However, due to supply constraints, the board is currently limited to one unit per customer.
The kit is designed to be breadboard-friendly and comes in a compact, gumstick form factor. It includes a full-size Ethernet port, MIPI Camera Serial Interface (CSI), and Display Serial Interface (DSI) to take advantage of the onboard H.264 hardware codec. Additionally, 0.1″ pin headers expose general-purpose input/output (GPIO) connectivity.
The board has Espressif’s ESP32-P4, which integrates two 32-bit RISC-V cores running up to 400MHz, 768kB of static RAM, and support for up to 16MB of external SPI flash memory. A microSD card slot provides additional program and data storage. Other hardware features include SPI, I2C, I2S, UART, TWAI, and SDIO Host 3.0 buses, along with analog-to-digital conversion (ADC), pulse-width modulation (PWM), and other essential interfaces.
Despite the board’s versatility and low cost, availability remains limited. “As ESP32-P4 processors are still available in limited quantities,” Usunov explained, “only one board per order is allowed. Orders exceeding this limit will be put on hold and not processed.”
The Kit is priced at €16 (approximately $17), plus shipping, and is currently available on the Olimex web store. True to Olimex’s commitment to open hardware, all design files for the Kit are published on GitHub under the CERN Open Hardware License Version 2 (Strongly Reciprocal).
“ESP32-P4-DevKit is our first development board with the new Espressif dual-core RISC-V processor [ESP32-P4],” said Olimex founder Tsvetan Usunov. “The ESP32-P4 has support in ESP-IDF 5.4, and we successfully built demos for Blink, iperf, MIPI-CSI, and SDmmc.”
