ARDUINO NICLA SENSE ME
Tiny, accessible machine learning lab!
Arduino’s Nicla series are diminutive
boards (22.86mm square) with
castellated edges for easy integration
into other projects, and the Sense ME
is packed with high-quality motion and
environment sensors from Bosch, plus
an edge AI-ready nRF52832.
ADAFRUIT FEATHER RP2040
USB-C! Feather! RP2040! Pink!!
With four times the flash of the Pico,
Adafruit’s Feather spin on the RP2040
joins dozens of boards and “wings”
with the familiar form factor, including
such conveniences as LiPo charging,
a Stemma QT/Qwiic connector, RGB
NeoPixel, and USB-C for power,
programming, and debugging.
ARDUCAM PICO4ML
Machine vision workshop for $26!
Arducam’s RP2040-based Pico4ML
offers a complete tinyML lab for $26,
thanks to a built-in HiMax HM01B0
QVGA camera, microphone, 0.96"
TFT display, and 9-axis IMU, all
while consuming just 60mA during
inferencing!
