SeeedStudio launched an intriguing new Kickstarter project, the RePhone.
The core of the phone is provided by the RePhone Core GSM + BLE module, or by the RePhone Core 3G module, which provides a faster data connection but lacks BLE support. However, beyond these two core modules offering the cell connection are 8 more add-on modules from Seeed’s Xadow range — a 1.54-inch touch screen, a 5×7 LED board, an NFC board, a GPS board, an audio board, a basic sensor board, a GSM breakout board and an Arduino-compatible microcontroller. It also supports Bluetooth. You’re going to want to get the $49 Kit Create, a tiny watch-like system that includes a little case and all the modules. It’s like getting a tiny unlocked cellphone for under $50.
However the RePhone is about more than just the hardware, Seeed has developed library support not just for the Arduino, but also for Lua and Javascript, as well as a full SDK based around Eclipse for C/C++ developers, and IFTTT support.
