New & Notable
ROCK PI 4 MODEL C+
Pi-compatible contender!
What may appear at first blush as
just another Raspberry Pi is in fact
Rock Pi’s 64-bit Rockchip RK3399-
powered SBC in a Pi-compatible form
factor. The dual-core Cortex-A72 and
quad-A53 provide a blend of power
and efficiency for running Debian,
Ubuntu, or Android, and onboard
M.2 SSD and eMMC module support
trump the Pi’s mSD storage.
UNEXPECTED MAKER
FEATHERS2 NEO
5×5 RGB matrix onboard!
An RGB LED on an ESP32-S2-based
Feather isn’t cool. You know what's
cool? 26 RGB LEDs on an ESP32-S2-
based Feather!
PIXELBLAZE V3 STANDARD
Epicenter of RGB LED hype!
Command complicated RGB LED
contraptions without coding! The
Pixelblaze provides plentiful patterns,
or write your own in JavaScript with the
built-in web-based editor to drive up to
5,000 pixels!
