HFT-Core-Module
V1.1 PCB after placement was done:
These are the included devices for the V1.1:
- CPU: ST Microelectronics STM32L496ZGT6P (80MHz ARM Cortex-M4 w/ 1MB FLASH / 320kB RAM)
- ext. Flash and EEPROM (8MB more data to be kept outside of the MCU / 8kB configuration data)
- GSM / GNSS / BT: SIM868 (SMS / GPRS / GPS, Glonass ...)
- VHF/UHF FSK and LoRa: SX1262 (VHF TX/RX)
- VHF/UHF All but Lora: AX5243 (VHF TX/RX)
- Accel/Gyro/Mag: BNO085 (3Axis-Acceleration, 3Axis-Gyro, 3Axis-Magneto - motion tracking engine)
- Baro/Hygro/Temp/AirQuality: BME680 (0.12Pa equiv. 1.7cm)
- VCTCXO: CFPT-141_20MHz (being synchronized to the GPS 1PPS signal by pulling the VC)
- Clock PLL (distributing any clocks that are needed)
- Audio ADC and DAC (connected to the I2S facilities)
- LCD 16x2 display (draws less than 1mA from the battery)
- E-Ink-Display w/ 200x200px (more fun with even less energy)
- Archer Headers (expanded by up to two daughter boards)
- SMA sockets: GSM, GNSS, BlueTooth, SX1262, AX5243 (each device has its own antenna socket)
- PMICs for 12V, USB, Solar-Cells, 3.3V, 1.2V (high efficiency on board)
- Electronic Switches: Subcircuits to be powered on/off by request (ultra-low-power to full-media)
- LiPo-Connector: 1-cell 3.7V (high power request by the SIM868 device to be satisfied)
- ... and some more fun... (what is missing? ;-)
