02CAPABILITIES

Your ideas. Backed by real capabilities.

AI DIY01

AI-Native Development

Describe your goal. Your AI assistant handles firmware, models, and application development, then verifies the result on real hardware.

AI02

On-Device ESP-DL Inference

Object detection, pose estimation, and image classification; load a quantized .espdl model in one line — real-time, offline, on device — or bring your own PyTorch / TensorFlow model.

VLM03

Cloud Vision LLMs

Stream straight to OpenAI-compatible vision APIs and tap multimodal models like GPT-4o — complex scene understanding with no local compute.

IMG04

Image Processing

Drawing, filtering, color tracking, feature detection, QR codes, barcodes, and AprilTags.

CDC05

Hardware Codec

H.264 / MJPEG / RTSP and USB CDC live preview, saturating the on-chip multimedia accelerators.

IO06

Rich Peripheral Support

Cameras, displays, SPI, I2C, UART, SD cards and more work out of the box, with a MicroPython machine-compatible API.

03GET STARTED

Connect your board. Keep it simple.

PROMPTA request for your AI
