LOLIN32 by Wemos

The WEMOS LOLIN32 Lite Board is the successor to the ESP8266. In addition to WiFi, the microcontroller also has Bluetooth and Bluetooth LE as well as more IO pins and improved analog inputs. The ESP32 can be programmed under Arduino. However, the board needs to be integrated first. I recommend the ESP32 only for advanced users, as it is not yet supported by all Arduino libraries. In addition to the WiFi/BLE SoC, the Lolin32 board includes a CH340G that converts USB to serial and allows your computer to communicate with the microcontroller. The LOLIN32 also has a LiPo charger with connection for 3.6V LiPo’s, so you can realize your ESP32 project battery-powered and really wireless.

The ESP32 is great for small projects where you don’t need so many I/Os, processing power or interfaces.

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.
