necessaryevil86,
Before you make the order, it¡¯s better to ask seller the detail spec. the list below is what the current NanoVNA supports.
- 3.3V (5V if jump wire)
- 4-wire SPI. It seems the eBay one is parallel
- Raw resistive touch signals, X+, X-, Y+, and Y-. The eBay one is SPI with interrupt (TP_IRQ). If you purchase this one, you not only have to do some jump wiring, but also modify the touch related C code. You can refer to the NanioVNA-F, which uses SPI for touch function.
