The Raspberry Pi 4 is much faster than every prior Raspberry Pi, but what if you could squeeze much more than the base 1.5 GHz out of its Broadcom BCM2711B0 CPU? Fortunately, it’s easy to overclock any Raspberry Pi and you can do it just by tweaking a few lines of text in the /boot/config.txt file. Now, with the latest firmware, we were able to reach a speed of 2,147 MHz, which we believe is a new high.
With prior firmware, the Pi 4 B’s processor was limited to a maximum overclocked frequency of 2 GHz, which is pretty good all by itself. However, the latest update let us push it up another 147 MHz. We were also able to increase the GPU clock speed to 750 MHz, a big boost over its 500 MHz stock speed and the 600 MHz we had overclocked it to previously.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
