Project introduction video:
GSM signals receiver test:
FM signal receiver test:
Sine wave signal transmission test:
Loopback signal test:
The pluto-sdr firmware transplantation work is all done, flashing the firmware without hacking the system, the default is AD9364.
FPGA: ZYNQ7010/7020 (ZYNQ7010 and ZYNQ7020 can be replaced with each other, if you need more hardware resources, please use ZYNQ7020)
RF: AD9361/AD9363/AD9364 (the three chips can be replaced with each other, the difference lies in the bandwidth. Among them, AD9361 has better performance, try to use the ABCZ ending chip, which is different from BBCZ)
AD9363ABCZ Band: 325 MHz to 3.8 GHz
AD9363BBCZ Band: 650 MHz to 2.7 GHz
RAM Memory: DDR3 256M16
USB-PHY: USB3320C
GMAC-PHY: RTL8211E-VL (RTL8211E has two endings, VB and VL, where VB level is 3.3V/2.5V, VL is 1.8V)
QSPI FLASH: W25Q256 32MB
Power supply topology diagram
block design
Support Pluto-SDR firmware transplantation, OpenWiFi (ZYNQ7020 FPGA required), support adi official ZED+AD-FMCOMMS2/3/4 related firmware code
Design software: Altium Designer Kicad
Number of layers: 4 layers （signal layer[1]、GND[2]、POWER[3]、signal layer[4]）
Craft: JLC PCB Craft
Impedance: not supported
The impedance version will be tested in March 2021, and the openwifi port is currently undergoing normal transceiver tests.
- Support for Zynq-7020 and Zynq-7010 in 400pin BGA package
- Support 2R2T transceiver mode
- 4 layer board to reduce cost
- SD slot for running real Linux distros
- Support Gigabit Ethernet
This is the PCB rendering
This is the physical picture of the PCB
This is the details of the PCB RF part
Ethernet can work stably at 1000M (using single-arm routing for testing in the figure)
AD9363 initializes the normal graph using adi no-os test environment
Pluto-uboot transplanted successfully
Pluto firmware works fine
Receive GSM signal normally
Hack into AD9364 to receive FM signal
Two PCBAs receive and send each other test
PCBAs can be stacked on each other and connected through Gigabit switches and routers
Support SDR-SHARP
- Continue to optimize the RF part to reach the adi official demo board indicators
- Impedance design based on four-layer pcb
- To be completed in January-February of 2021, to complete the relevant transplantation work of openwifi
- Design the impedance version in March 2021
- Conduct commercial index tests on the impedance version in April 2021
- When the commercial version is launched at the end of April 2021, it will support adi's official SDR firmware (ADRV9364 packet), openwifi, and openbts openbts, etc.
