A huge update for TensorFlow Lite for Microcontrollers on Raspberry Pi Pico #RaspberryPi #ML #AI @Raspberry_Pi
It’s been three years since the RP2040 port of TensorFlow Lite for Microcontrollers. The work was done by Pete Warden, who at that point headed up the TensorFlow mobile team at Google. Since, the RP2040 port has been languishing. But a couple of weeks ago, that all changed. Raspberry Pi News reports:
Now at Useful Sensors, Pete has been doing some interesting things with RP2040. He has just upstreamed the last three years of changes — after all, as he puts it, “We all love pull requests with 1,129 changed files, right?” — and he’s taking on maintenance of the port on a best-effort basis.
The code now uses both cores of the RP2040 microcontroller.
The upshot? These updates and changes reduce the time for the person detection benchmark code from 824ms to 588ms. That’s a ×1.4 speed increase!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
