FindMeSAT
GPS assisted tracking device with GSM (SMS & GPRS) and Bluetooth connectivity.
List of devices
- CPU: Atmel ATxmega256A3BU (256kB Flash / 16kB RAM / 4kB EEPROM)
- GSM / GPS / BT: SIM808 (SMS / GPRS / ...)
- VHF/UHF: AX5243 (VHF TX/RX)
- Accel/Gyro/Mag: MPU-9250 (3Axis-Acceleration, 3Axis-Gyro, 3Axis-Magneto)
- Baro/Temp: MS560702BA03-50 (0.2 meter height resolution, better than 0.01°C resolution)
- Hygro: SHT31-DIS (hygrometer within the air stream of the board)
- VCTCXO: CFPT-141_20MHz (being synchronized to the GPS 1PPS signal by pulling the VC)
- GSM antenna: within the PCB (works for each band)
- BT antenna: within the PCB (not used yet)
- GPS antenna: external active antenna via MCX connector
- VHF/UHF antenna: external passive antenna via SMA connector
- LiPo: 1-cell 3.7V (high power request by the SIM808 device to be satisfied)
