RS232 level shifter for the Raspberry Pi Model B
by Mark J. Blair nf6x@nf6x.net
This board is an RS232 level shifter for the Raspberry Pi Model B, which is the version with a 26-pin J1 next to an 8-pin J5. It is not intended for use with any other versions of the Raspberry Pi board. The external RS232 connection is via an RJ45 jack wired to the Yost serial port wiring standard.
It provides full hardware handshaking, with the following pin assignments:
| GPIO | Function | Dir | RJ45 Pin |
|---|---|---|---|
| GPIO14 | TXD | out | 6 |
| GPIO15 | RXD | in | 3 |
| GPIO17 | DCD/DSR | in | 2 |
| GPIO18 | DTR | out | 7 |
| GPIO30 | CTS | in | 1 |
| GPIO31 | RTS | out | 8 |
| GND | GND | 4 | |
| GND | GND | 5 |
0 ohm series resistors allow rewiring as necessary.
