UDOO KEY: Raspberry Pi RP2040, ESP32 and Clea AI Platform

UDOO needs no introduction. It is a well known company developing x86 based board and the popular Udoo Neo low-cost ARM based SBC which was powered by NXP® i.MX 6SoloX processor.

They have now release another board UDOO Key for edge Computing and this time it is microcontroller platform using Raspberry Pi’s RP2040 and ESP32 Dual Core. Kickstarter Campaign is going on and has already got 150K USD funding while I am writing.

When they say their platform enables AI on the edge, they are not only talking about hardware but AI platform which helps develop applications with significantly less effort and time.

Software Development

Both microcontrollers can be programmed using different environments, such as TinyML, TensorFlow Lite, MicroPython, C/C++, and many more, giving you plenty of options to streamline your AI application.

UDOO Key remains Open source and even their AI platform is built on open source projects Astarte and Edgehog.

Astarte allows the developers to manage and process IoT data: from collection to processing up to data orchestration. It features a full-fledged SDK for ESP32 based on the Espressif IoT Development Framework (ESP-IDF), so you can be starting building in a matter of minutes and with just a few lines of code.

Edgehog enables fleet device management and OTA updates, enhancing ESP32’s firmware with a full-fledged device lifecycle solution.

Limitless Possibilities

It can be used to develop various applications like:

  • Sound detection, voice recognition
  • With external Camera: object detection, classification, face recognition
  • Factory floor monitoring
  • Machine Monitoring, etc

Availability and Cost

Kickstarter campaign is going on and $4 per unit early bird offer is already gone, but you can get $9 UDOO KEY which has microphone and accelerometer.

Shiping cost varies from 6$ to 15$, for India it is 15$.

As per their announcement the deliveries are scheduled to start in January 2022. Let us hope everything goes well and they manage through the chip shortage.

I have already ordered 2 sets of UDOO Key as one is never enough 🙂


      1. Edge device which can take live RTSP feed and perform object detection and classification.
