      RePhone is one of the most unique and interesting development board platform that created by Seeed Studio, with RePhone you can not only DIY a special phone for yourself, but also enchant things around you with cellular connectivity. The first edition of RePhone core is Xadow – GSM+BLE, this time we provided another 2 edition of RePhone core which with higher performance and lower power consumption, one of them is the RePhone Core 2G-AtmelSAMD21 v1.0

      The RePhone Core 2G-AtmelSAMD21 v1.0 is a new Arduino compatible RePhone core 2G board, which is based on Atmel’s SAMD21 and SIM800H, Most features of RePhone Core 2G-AtmelSAMD21 v1.0 is the same as Xadow – GSM+BLE, such as offering rich range of communication protocols – GSM, GPRS, and Bluetooth, supporting quad-band 850/900/1800/1900Mz, and supporting 2G Nano SD card. But the solution of Atmel’s SAMD21 plus SIM800H has dropped power consumption a lot comparing to Xadow – GSM+BLE. If you are looking for a high-performance and low power consumption Rephone core to enchant the world, the this new RePhone core 2G module is the best choice.

      We also provided a more economic version RePhone core 2G Atmel32u4, the only difference is the MCU. Click here to find it.
