UEXT Lora module (868 MHz, EU) with Duck antenna
868 Mhz is the LoRa frequency for Europe. This module expose a uFL connector to connect the PCB antenna (offering 3 dBi of gain). The Duck Antena includes a 30cm cable.
This UEXT module is easy to connect on board exposing UEXT connector. You can also connect the module with Dupond wires.
The SX1276 module uses all the lines available on the UEXT SPI (main interface), UART and I2C. Uart and I2C bus on the UEXT are also required.
What's UEXT ?
UEXT is a connector carrying I2C bus + SPI bus + Serial + 3.3v power. It use a very standard 10 Pin IDC connector. It is quite easy to add sensors and extension board with UEXT connector... just plug it or wire it with IDC ribbon! Great.
Our favorite is the carrying of I2C bus allowing to easily add several sensors and expansion board. On the other side, SPI would be welcome for fast data transmission like remote screen. The serial connexion could be made compatible with RS-232, RS-422, RS-485, DMX512, MIDI by using appropriate level-shifting circuitery.
This connector is usually available on almost Olimex's product including nano computers. It is a great way to add extension boards on products like ESP8266 WiFi microcontroler or microcontroler board. UEXT is suited for prototyping, school learning (no need for iron) and industrial solution (Olimex produces Industrial Grade boards).
See our UEXT expansion or all products exposing UEXT connector on the shop, the Olimex's UEXT collection, Wikipedia to learn more about UEXT.
