NodeMCU ESP32-C2
by NodeMCU
The ESPC2-12 module adopts the ESP8684 chip, which is a universal WIFI and low-power Bluetooth dual-mode module with powerful functions. The module adopts onboard antenna and external antenna, and is equipped with 4MB SPI FLASH. Pin connectors (row pins), all available GPIO pins have been led out to the row pins of the development board. The mainstream type-c USB interface can be used as a power supply for development boards or a communication interface between PC and ESP8684 chips. USB to UART bridge, single chip USB to UART bridge, providing a transfer rate of up to 3 Mbps. ESPC2-12 is an extremely low-power SoC designed based on ESP8684 and equipped with RISC-V 32-bit single core processors. It supports IEEE 802.11b/g/n (2.4 GHz WiFi) and BT 5 (BLE) modules.
Features
- Versatile Development Kit:Comes with a comprehensive SDK and supports various protocols, making it ideal for a wide range of IoT projects.
- WiFi & Bluetooth Connectivity:Supports IEEE 802.11 b/g/n (2.4 GHz WiFi) and BT 5 (BLE) modules, enabling seamless wireless communication.

CircuitPython 9.2.0-beta.1
This is the latest development release of CircuitPython that will work with the NodeMCU ESP32-C2.
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.
