GPS Classic M8N – IST8308
Background
Features the latest Taoglass Antenna tuned for GPS + GLONASS, which provides a higher gain compared to any of its predecessors (from 1.5dBi to 5dBi), as well as the IST8308 compass by iSentek, which is based on the legendary HMC5983 technology and licensed by Honeywell. In addition, the IST8308 is temperature compensated and has a micro USB port which enables you to access all u-Blox features via u-Center and power the device.
Extra Info: HMC5983 and the IST8308 are pin-compatible (either one is placed on the board, but not both). There is a third option, QMC5883L, that we might support later.
