Hardware
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/).
Visit radino32 software for more information about the Arduino IDE.
For detailed information about our library for the Arduino IDE look at the radino Library documentation.
Range test
For some range tests we used two radino32 SX1272 on radino Spider RP-SMA and a 15 cm antenna.
