Pcbcupid GLYPH C6 by Pcbcupid
The Pcbcupid GLYPH C6 is a compact development board based on the ESP32-C6-MINI-1-N4 module, designed for next-gen IoT applications requiring Wi-Fi 6, Bluetooth LE, and Zigbee/Thread (802.15.4) connectivity in one footprint. Onboard LiPo charging makes it ready for portable and battery-backed deployments.
The board features an onboard GLINK connector — QWIIC/STEMMA QT compatible — for solder-free sensor and module integration. It includes auto power switching between USB and battery, battery voltage sensing, and a slide switch to cut battery power entirely.
The GLYPH C6 uses a built-in USB bootloader. Hold BOOT while plugging in USB to enter bootloader mode — it appears as a COM port for flashing.
For peripherals, the ESP32-C6 exposes I2C, SPI (including SDIO-capable pins), and UART via the GPIO matrix. The chip also includes a dedicated low-power (LP) core with its own UART and I2C for ultra-low-power peripheral handling independent of the main processor.

CircuitPython 10.3.0-alpha.4
This is the latest development release of CircuitPython that will work with the Pcbcupid GLYPH C6.
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.
