RAK1921 WisBlock OLED Display Module, I2C SSD1306, Text and Graphic Visualization, for Meshtastic

Soldered in easily and works great

Connected and functioned great on a RAK4631 system.

I bought this with the rest of my meshtastic gear out of fear of having no idea what was going on with my hardware. For a home node I’m not sure I needed it as a USB connection to my laptop and/or Bluetooth to my phone gives me all the info I need. BUT I’m describing an ideal workbench environment where everything happened to work right the first time. Maybe more valuable in a situation where your hardware in the field isn’t working and you need some insight.Just a side note, soldering could be a challenge if you’re old like me and don’t have steady hands due to carpal and cubital tunnel problems. By its very small nature there isn’t a lot of room for error whether you try to mount directly to the board or you try to use the included connector hardware.

Nice display for the Wisblock. Solder connections easy to install. Does it's job.

Order a pack of OLEDs from somewhere else. This was probably all in the description I didn’t read, but it’s just a standard 64x128 oled (to lazy to look up the ubiquitous model number) and RAK is super tiny mounting hardware.I almost gave this like one star but… the whole WisBlock ecosystem is so slick this gets some halo stars.If you want exactly one to try… meh, okay... But the headers weren’t even soldered. You can get 2-3 of these with a pre-soldered header, here, for the same price.

It works fine, but you can buy five of these for 10 bucks anywhere else on Amazon. It’s a universal screen, the Wiz block doesn’t have a proprietary screen. I’ll take five of these versus one for the same price.
