Gemini by 0xCB
The 0xCB Gemini is our Waveshare RP2040-Zero compatible microcontroller. It includes all the features of it’s bigger brother, the 0xCB Helios, in a much smaller form factor.
Technical details
- Powerful RP2040 32-bit Cortex M0+ dual core running at 133 MHz and 264kB SRAM.
- 16MB/128Mb QSPI FLASH chip for storing files and code
- 3.3V 500mA LDO, PTC fuse and ESD protection chip
- 4 pins configurable as analog inputs
- GPIO16 is level shifted to 5v to drive the onboard aRGB LED (DIO is connected to GP16)
- USB VBUS detection on GPIO19 for split keyboard side detection
- UF2 bootloader for drag & drop programming via your file manager
- easy to use Single button boot and reset circuit push to reset and hold >500ms to enter bootloader
- 4 pads for use with an external USB socket/daughterboard
- USB-C connector lets you access built-in ROM USB bootloader and serial port debugging

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.
