WiFi LoRa 32 V3
by Heltec Automation
WiFi LoRa 32 is a classic IoT dev-board designed & produced by Heltec Automation. Since its launch in 2017, it has been loved by developers and makers. The newly launched V3 version has the same pin sequence as the V2 version and retains Wi-Fi, BLE, LoRa, OLED display, and other functions.
It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers.
WiFi LoRa 32 （V3） is a part of the “Heltec LoRa“ series, with the following features
- Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual-core processor, five-stage pipeline rack Structure, frequency up to 240 MHz).
- SX1262 LoRa node chip.
- Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.
- Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching).
- Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface for LoRa use.
- Onboard 0.96-inch 128*64 dot matrix OLED display can be used to display debugging information, battery power, and other information.
- Integrated CP2102 USB to serial port chip, convenient for program downloading, and debugging information printing.
- Support the Arduino development environment.
- With good RF circuit design and low-power design.

This is the latest development release of CircuitPython that will work with the WiFi LoRa 32 V3.
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.

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.
