Tenrec is a Raspberry Pi 4B
I am setting it up as a build machine
2020-May-09 arrived from Newark
Hardware
- 4GB 4B
- Seeed heatsink kit so cute, had to have one. Probably superfluous.
- 7" Pi touch screen from Element14
- Multicomp Pro case, clear
- Corsair GTX 240GB SSD
- Startech USB3 SATA3 cable (lsusb id is 174c:55aa with ASMedia ASM1053E chipset)
I drilled a couple holes in the bottom of the case, attached RAM mount hardware.
I am borrowing the USB3 hub that lives in the back of my monitor and using it to power an Apple keyboard and a Startech USB3 SATA cable.
The combination of USB3, SATA3, and a reasonably fast SSD is working well.
Screen and touch screen rotation
In this case, the 7" screen is upside down. You can fix this! https://raspberrypiprojects.com/raspberry-pi-rotate-touch-screen/
Power
I had the lightning bolt low voltage warning almost continuously until I plugged in only a hub to the USB ports. I am using a 5V 4A switching supply and a USB-C cable. My power meter says it's pulling just over an amp at 5.1 volts.
Software
I installed Raspian Buster Lite on the 8GB SD card that I am using to boot. I installed the window environment on the SSD. Also it goes without saying, emacs.
sudo -s dpkg --configure -a apt update apt full-upgrade reboot apt install emacs-nox apt install xserver-xorg xinit apt install raspberrypi-ui-mods reboot
Now I have a lightdm login screen, so I log in. I think the server has an idea that I have a 4:3 screen too and not 16:9 so that needs fixing.
