PZSDR P047 RF-ADC and RF-DAC software-defined radio (SDR) board is based on AMD Zynq UltraScale+ ZU47DR RFSoC with a quad-core Cortex-A53 processor, a dual-core Cortex-R5F real-time CPU, FPGA fabric, eight RF ADCs, and eight RF DACs.
The board features 6GB of DDR4 memory (4GB for PS, 2GB for PL), 8 GB eMMC flash, and 512 Mbit QSPI flash, plus microSD card and M.2 NVMe sockets for storage, a mini DP video output, a Gigabit Ethernet RJ45 port, two 100 Gbps QSFP28 cages, a USB 3.0 port, plus JTAG and serial debug interfaces, and a 32-pin IO header. It makes use of all RF channels of the RFSoC with 8 receiver and 8 transmitter connectors, plus various clock inputs. The company says the PZSDR P047 is ideal for advanced MIMO wireless applications such as cellular and shortwave communication.

Puzhi promises that backers will have access to FPGA logic, Arm Vitis, PetaLinux, RF, and PYNQ demos (see video below for the latter) to help them get started, and the PDF version of the schematics will be released after the crowdfunding campaign is complete. In the meantime, they have released a user manual, which mainly provides hardware details.
Last time we wrote about an AMD Zynq RFSoC platform was in 2022, when we covered the Avnet XRF16 SoM based on Zynq UltraScale+ Gen3 ZU49DR RFSoC and associated carrier board. The ZU49DR is similar to the ZU47DR used here, except it doubles the number of ADC and DAC channels to sixteen. At the time, the SoM sold for a cool $24,995, and the carrier board for $4,995.
By comparison, the Puzhi PZSDR P047 feels like a bargain with a pledge of $6,699 through Crowd Supply. The reward includes the board itself, a metal enclosure, a 12V/3A power adapter, a GPS antenna, 23 RF cables, a USB Type-C cable, a two-sided USB 3.0 cable, a Gigabit Ethernet cable, a 3-pin XH2.54 cable, a 32 GB microSD card, and an SD card reader. The price includes worldwide shipping, and deliveries are scheduled to start by November 2026. I’m not sure why the company decided to go with Crowd Supply here, since they already have a similar ZU47DR board listed for $5,545.41 on AliExpress, including shipping.
