Read More…A bunch of xc7z020-clg400 boards from unknown sources, for repurposing and/or chip scavenging. 3 long ones and 1 short one, and another long one with the chip already removed for pin probing.
I've measured the power supply and JTAG pinouts for the longer board. JTAG contact in Vivado confirmed.
Board(long) front side: the ZYNQ FPGA, two DDR3 chips, FPC connectors, probably USB phy. Board(long) back side: micro SD card slot, SPI flash (probably for ZYNQ booting), 2x5 pin 2.0mm connector marked for USB DP/DN and UART RX/TX, misc pin headers (measured to contain GND, 1.8V, 3.3V, 5V, and JTAG), 2-pin header marked LED+ and LED-.
I acquired these from flea market for potential repurposing, but later I lost interested, partly because the FPCs are hard to handle, and there's only a batch of three same boards (one already half-disassembled). You can continue from where I left, I can remove more chips and clean up the solder pads for better reverse-engineering probing if needed. Details/Silkmarks of the chips can be given if requested.
If you need some cheap ZYNQ 7020, no matter to build new boards or repurpose this one, then this is your choice!
