µPico
by RF.Guru
The µPico Stick is an affordable and high-performing development board, utilizing the RP2040 PICO chip developed by Raspberry Pi. You can also opt for a stylish case for added protection.
The RP2040 microcontroller chip, often referred to as “Raspberry Silicon,” features a dual-core ARM Cortex-M0+ processor clocked at 133 MHz, 256 KB of RAM, 30 GPIO pins, and various interface options. Additionally, it boasts 2 MB of onboard QSPI flash memory for storing both code and data.
At RF.Guru, we employ this board for internal development and exploration of new product ideas. Given our focus on radio applications, we required a board with outputs that produce minimal noise.
Enhancements Include:
- Improved 3.3V LDO for reduced ripple (less noise).
- Incorporation of ESD protection and noise filtering on both the USB Data bus and the 5V DC input.
On Board IO
- 2 push buttons
- 2 RGB Leds
- A Piezo buzzer for audio output
- Pins It exposes RP2040 pins 16 till 24. 2 ADC ports, I2C bus, SPI bus and UART0

CircuitPython 9.1.0-beta.1
This is the latest development release of CircuitPython that will work with the µPico.
Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.
Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
