radino32 SX1272 radino32 SX1272 radino32 Pinout

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.
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 are pin-to-pin compatible.

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/).
For the Arduino IDE Boards Manager follow URL is required:


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 documentation.

Common problems regarding radino modules and the Arduino system: Common problems

Windows will automatically install the wrong bootloader driver. Please follow the instructions for Windows 7 oder 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: Upload binary on radino32

Working with Arduino IDE

The Arduino IDE required follow includes for using the radino32 SX1272.

#include <SPI.h>
#include <radino32_sx1272.h>

Range test

For some range tests we used two radino32 SX1272 on radino Spider RP-SMA and a 15 cm antenna with 868 MHz.

Long range test

29.5 km transmission with the radino32 SX1272 from Dresden „Rockauer Höhe“ to Altenberg „Geisingberg“ with longe range settings.
