將USB連接到串行TTL PL2303HX連接到Raspberry Pi


3

我有一個USB到串行TTL PL2303HX(多產芯片組),我想連接到我的Pi。我的Pi模型是2011.12。

USB到串行適配器有5個PIN,標記如下:

  • 3V3
  • TXD
  • RXD
  • GND
  • + 5V

我收到了4根USB到串行適配器的電纜(4個母對母dupont連接器)。

我已經看到了GPIO的各種diagrams,但是我不確定GPIO上的哪個PINS進入適配器上的PIN。

問題:GPIO上的哪些PIN需要連接到USB適配器上的哪些PIN?

You only need to connect GND, RXD, TXD

GND => PIN 6

RXD => PIN 8

TXD => PIN 10

In addition to John La Rooy's answer, I've also connected VCC (i.e., +5V) to PIN 2. Thus, my Pi receives enough power from my computer to boot from a USB key.

I can tell you the WRONG way. I did as above but also connected the 3v3 pin on the prolific dongle to the 3v3 pin on the pi and apparently it fried the pi. Not sure why. I wish someone would give an explanation.
