my own expansion board which converts the 1.27mm pitch connector to 2.54mm pitch connector for Z-turn board (http://www.myirtech.com/list.asp?id=502) from MYiR
A lot of design is borrowed from the IO Cape board (http://www.myirtech.com/list.asp?id=532) of MYiR, where I converts the Connector 1 to 6 PMOD compatible (2.54 mm dual row 12 pin header) headers and 1 40 pin FFC/FPC connector (for LCD); and Connector 2 to 2 PMOD headers plus 2 2.54mm dual row 34 pin header. Especially:
| Connector | Comments |
|---|---|
| CN1, CN2 | two 1.27mm pitch dual row 80 pin headers from Z-turn board |
| J1,J2 | two 2.54mm pitch dual row 34 pin headers for FPGA differential pin (12 pairs each); |
| LCD | 40 pin FFC/FPC connector; |
| MISC | PMOD header for I2C; |
| I2S | PMOD header for I2S and HDMI; |
| J3, J4, J5, J6 | PMOD header for FPGA differential pin (4 pairs each); |
| ADC | PMOD header for XADC input (two pairs of analog input); |
| MIO | PMOD header for ARM IO pin (8 pins); |
| Note | the differential pins is not ready for high speed differential usage yet, as the length is not properly configured. |
