# M17_ANL_v2
|
||||
New M17 hotspot/analyser, this time with ADF7021
|
||||
|
||||
# Schematic
|
||||
is still draft, not released yet.
|
||||
## Schematic
|
||||
Diagram was not tested yet.
|
||||
However, schematic and PCB layout is still work in progress.
|
||||
PCB design was put into production in 1 February 2020.
|
||||
Testing will take aprox. 2 months.
|
||||
|
||||
## Technical details
|
||||
|
||||
M17_ANL_v2 is a radio modem designed especially to support interaction with existing M17 capable radio terminals & repeaters. It also means packet acquisition, for debugging cases or sniffing, just for fun idk.
|
||||
However M17_ANL_v2 can be used to receive and transmit raw digital data - it's by design protocol agnostic.
|
||||
|
||||
### Parameters
|
||||
|
||||
* Operating freqency range is 420MHz to 450MHz (M17 operates within amateur frequency band 430-440MHz) - after a few changes of RF elements values also another frequency bands
|
||||
* Modulation schemes selectable - 2FSK, 3FSK, 4FSK, MSK and FM (for M17 - 4FSK)
|
||||
* Output power level is set from -16dbm up to 10dbm (in 0.3125 dB steps)
|
||||
* Data rate is set from 0.05 up to 25 kbps (for M17 - 9600 bps)
|
||||
* IF filter bandwidth selectable - 12.5 kHz, 18.75 kHz, or 25 kHz
|
||||
* Configuration, transmit and receive by AT commands - over USB-CDC
|
||||
* All registers of ADF7021 also configurable by manual mode
|
||||
* Additional 4 GPIOs - first pair can be used as I2C interface, second can be UART
|
||||
* Four different colour LEDs - PWR, SYS, RX and TX - indicate the state of the device
|
||||
* Programmable by SWD interface
|
||||
|
||||
MORE TODO
|
||||
|
||||
|
||||
### Most important ICs used in project
|
||||
|
||||
* STM32F303CBT6 - MCU which controls data flow(PC <-> RF TRX), and radio parameters.
|
||||
* ADF7021 - radio transceiver.
|
||||
