📦 What's Inside

This dataset consolidates hardware details from multiple embedded ecosystems (PlatformIO, vendor documentation, and silicon datasheets) that toolchains typically omit:

• Memory Limits: Exact maximum RAM and Flash/ROM capacities in bytes.
• Electrical Parameters: Operating voltages (e.g., 3.3V, 5V).
• Silicon Architecture: MCU model, CPU architecture (Cortex-M0+/M4/M7, Xtensa LX6/LX7, RISC-V, AVR), and clock speed (Hz).
• Communication & Bus Interfaces: Supported header interfaces (I2C, SPI, UART, CAN, USB).
• Connectivity: Built-in WiFi, Bluetooth / BLE, LoRa, Ethernet.
• Onboard Peripherals: Built-in screens/displays, buttons, LEDs, and environmental sensors.
• Toolchain Support: Frameworks (Arduino, Zephyr, ESP-IDF) and upload/debug protocols.

🚀 Quickstart in Python

from datasets import load_dataset
import pandas as pd

# Load directly from Hugging Face
ds = load_dataset("pyintel/open-board-registry", split="train")
df = ds.to_pandas()

# Find all 3.3V boards with WiFi and built-in screen
wifi_screen_boards = df[(df['screen'] == 1) & (df['connectivity'].apply(lambda c: 'wifi' in c))]
print(f"Found {len(wifi_screen_boards)} matching boards!")
