Review on 🔌 Raspberry Pi Module FTDI TTL-232R-RPI Debug Cable by Rafael Lee

I have ten Raspberry Pis in my house running 24/7, doing everything from an Apache web server to an NTP server with a cesium-based atomic clock. I have a few others that I use from time to time for special projects such as an IPv6 testbench or as a differential base for GPS and rover. Most of these Pis run headless, meaning they don't have a display, keyboard, or mouse. If they are on a home network I can use tools like ssh to log into them. But the ones I take into the field - and I mean literally in the middle of a field in a semi-rural area - have to have a TTL-232R RPI cable. I enable the serial port and serial console using the standard Pi setup program (don't forget to reboot the computer), connect the end of the cable to ground, send and receive pins on the Pi (6, 8 and 10 on the GPIO). ). header), plug the USB end into my laptop, and then use a tool like PuTTY (Windows) or Screen (macOS or Linux) to login to the Pi at 115200 baud, 8 bits, no parity. I can then interact with the Pi from the command line. It must be an invaluable tool for me: Revane says I have eight of them.
