We need to have a Sigfox / Lora board designer. Murata is soon releasing a new RF module which will be capable of handling both LORA and [login to view URL] board design we need must include sensors such as a three axis accelrometer and be capable of measuring current / amps . The Murata board will likely have a STM32L MCU which is fine to embedd a MAC address. The board will also need a solar charging circuit for a small 3.7 v or what ever it will require. the board will also require a mini USB connector for programming. If possible we would also like a RS 232 / 485 interface
