The In-Circuit radino32 SX1272 combines an STM32L151 with the SX1272 RF Transceiver in a small form-factor EMC-compliant module.
The core of the radino32 SX1272 is the powerfull STM32L151 by STMicroelectronics, which with 32-bit ARM® Cortex®-M3 CPU, 32 kbyte RAM, 256 kbyte Flash and 8 kbyte EPROM provides enough resources for complex functionalities.<br/>
The radino32 SX1272 is part of the radino-series, which supplies full-Arduino-compatible wireless communication devices in a small form factor. All [[radino Modules|radino Modules]] are pin-to-pin compatible.<br/>

With our Arduino Library for radino the radino32 SX1272 becomes fully Arduino-compatible, which enables easy programming using the Arduino IDE (http://www.arduino.cc/).<br/>
For the Arduino IDE Boards Manager follow URL is required:
 <nowiki>http://library.radino.cc/Arduino_1_8/package_radino_radino32_index.json</nowiki>
Visit [[radino/radino32 software]] for more information about the Arduino IDE and installation.

For detailed information about our library for the Arduino IDE look at the [[radino Library| radino Library documentation]].

Common problems regarding radino modules and the Arduino system: [[radino/radino32_software#Common problems|Common problems]]

<span style="color:#ff0000;">'''Windows will automatically install the wrong bootloader driver.'''</span> Please follow the instructions for [[radino/radino32_software#Install_bootloader_driver_at_Windows_7|Windows 7]] oder [[radino/radino32_software#Install_bootloader_driver_at_Windows_10|Windows 10]].


If you don´t want to use the Ardunio IDE, you can flash an existing .bin file with stm32flash. For more informations see: [[radino/radino32_software#Upload_binary_on_radino32|Upload binary on radino32]]
