Looks very interesting to play around with, but it isn’t clear what connector is needed. The data sheet says it terminates with DF37B-24DP-0.4V(51), so the mating part would be DF37NB-24DS-0.4V(51). However, the shape of the connector tail in the data sheet does not match the photo above. Can you confirm the connector?
Also, the attached data sheet isn’t enough to write a driver for this - you’ll need the ST7789V data sheet too.

Looks like fun to experiment with, but I’m curious how bright it is - is it too dim to use outside?
SparkFun please make a breakout board for this; perhaps a board that holds 3 or 4 of these in a row, and make sure it can be stacked side-by-side so you can build up a grid (crazy expensive Tic-Tac-Toe anybody?)
Also, just to be clear: This is not a color display - it is a monochrome display with a color backlight. You can set the backlight to any one of 64 colors, but each pixel is either black or showing the backlight.

Please consider making a version of this board with built-in level shifting. No need for a boost convertor; the 5v side can be powered by the project it is plugged into. Just start with this board, add the standard MSOFETs & pull-ups, and add the three pins for 5v0 (in), SDA5 and SCL5 (don’t get rid of the 3v3 power & signal pins though).
Yes, this can be used as a coupler to join two cables. However, longer cable runs might be less reliable. This page provides some guidelines , but it mentions 4 ft as a practical upper limit for Qwiic.

This is a great board! I particularly like the 3-contact “SVG”-style ports - installing female headers allows plug-and-play with Vex robotics sensors/devices. And the Qwiic port is great for all my I2C devices.
A few minor suggestions for future revisions:
(1) add a pin-1 indicator to the 2x3 ISP header.
(2) Figure out a way to get pads for the missing I/O ports, even if they can’t follow the SVG header layout exactly.
(3) Add a pad and cuttable-trace-jumper to each of the LEDs and the reset switch, so they can be repurposed if desired.
(4) Add a 3rd contact to J1 wired to un-switched VIN - allows power from the back but still switchable, and the existing switched-VIN terminal lets the board power other off-board devices.

The data sheet says “Mounting Bracket E69-1 supplied with A6A2-CWZ encoders”, but I don’t see any brackets in the product photos. Are brackets included? (I see there are two M3 mounting holes on the face, but I was curious of the clips are included or not)

With the updated description, I knew exactly what I was getting, and am very happy with what I got. These are perfect for adapting VEX robotics sensors and motors to non-VEX controllers.
Regarding wire thickness, I’m happy with the heavier wire, since it can pass decent current and is mechanically stronger than tiny wires - though the description should say what the wire gauge is. I agree they might be a bit heavy for RC applications where every gram matters.

Nice looking little board, and just the thing for a landscape lighting project I’ve got in mind.
One thing to consider for future board revs: Add a couple more solder jumpers so the resistors can be configured in series as well. That would provide a 3rd current option of ~167mA without requiring any additional parts.

;) SHT15 is the part number for the chip - SparkFun didn’t pick it.
(Well, they picked the part for this BOB, but they didn’t pick the name/number for the part).

I really like the microview - very cool product!
If you are considering a rev2, please add + and - markings on the plastic case near their respective pins. When this is plugged into a breadboard (without the programmer) the curved shape of the backshell makes it a bit hard to find the last pin in each row. This makes “off by one” errors possible with the 9V supply which is not a good thing.
