> are open hardware. Are they? I only see PDFs of schematics on their website, and no claims of being open. Of course with a breakout board like that there isn't really any secret sauce in the "source", just the expertise, trials and errors, and grunt work of layout. At that same level of "schematics available" dev boards, another option for a XC7A35T and 256MB DDR3 are the ones on aliexpress for $50, https://github.com/ChinaQMTECH/QM_XC7A35T_DDR3, though I don't think they have the transceiver pins exposed and are bring-your-own-jtag-programmer. All the IO is via 0.1" headers, which are going to be lower integrity but a LOT easier and cheaper to use. There's also a $99 XC7A100T board, https://github.com/ChinaQMTECH/QM_XC7A100T_WUKONG_BOARD, with 256MB DDR3, a gigabit ethernet phy, hdmi port, 0.1" headers and PMOD headers, and with some transceiver pins exposed. |
