OLED BOX is a 0.96" Oled display wired via i2c (TWI) with a mounting box. The mounting box is designed to be as compact as possible while making it as easy as possible to add a display to your project.
If you are like me, you've often wanted to add a display to an enclosure housing your Arduino Compatible Project, the issue is often that a display requires you to cut out a square in the enclosure in order to show the display's visible area.
Cutting out a rectangular opening can be difficult specially when it's done on metal enclosures, either a dremel or a really good router is needed for this, this makes it very difficult to get that opening for the display cut. Most people opt to either drill a very large holewhich exposes the display's circuit board or to mount the display on top of the enclosure which makes it a very fragile device.
OLED BOX makes this really easy as it only requires you to drill 3 holes, two 3mm/0.125" holes for mounting screws and a 10mm/0.4" hole in the center to pass the wire down.
The display is housed in a 3D Printed case and has a carrier PCB with a 1mm pitch JST SH connector (compatible with Sparkfun's Qwiic and Adafruit's STEMMA) for i2c and 4 SMD Standoffs (used for mounting the display to the case and mounting the case to your enclosure). A 4-pin 20cm JST wire and a 1mm pitch to 2.54mm pitch breakout board are included for easy mounting. OLED BOX comes fully assembled!
The JST SH 1mm connector/wire was chosen for it's size and to reduce the amount of wires hanging all over your enclosure!
These displays have a single fixed i2c address (0x3C), if you plan on using more than one with your Arduino you will need to use an i2c multiplexer like the TCA9548A. Both Sparkfun and Adafruit offer these already with JST SH connectors.
VCC for these can be 5V even if your MCU's logic is 3.3V, for example if you are using a Teensy 4.0 you wire the SCL/SDA pins to your Teensy, also GND to your Teensy's GND and VCC of OLED BOX can be connected to the Teensy's VIN (5v) pin, this is how I use them as it free's the 3.3V power from the Teensy's internal regulator. Also Pullup resistors are not needed for these displays.
