In lecture: 8-schematics why do we use four pin 0.1" connector (M04)…where do we connect this device plus wat value should be given to this M04? there are alot of unused input and output pins on the ftdi chip in my project…these unconnected pins give error when i run ERC…how to deal with these probs???
n yeah 1 thing more…do we have to give only the following 7 files:
GTL, GTS, GTO, GBL, GBS, GBO and drill file
are these 7 files enough for the fab house…will dey fabricate our chip correctly with these 7 files or we have to provide other things too for pcb fabrication
If you purposely don’t have anything connected to specific pins, but your ERC spits back an error because of it, then ignore the errors that say you don’t have anything connected to those pins. Pay attention to any others though.
7 files is the norm for a full featured 2-layer board. File extensions don’t matter so long as the following are covered:
If you look at the sample schematic, the 4-pin connector is called JP1, and is connected to RX, TX, Vcc, and GND. This is used to connect the USB-serial adapter to whatever device you are trying to talk to.
