ɖҿϝիɟթվ created this project to play arcade games on the Micro:bit:
The Micro:bit is a pretty decent platform for teaching kids to program, but you can’t really make arcade-style games for it. You only have two buttons and a 5×5 display. Perhaps enough for a very small snake game, but that’s pretty much it. That’s why I started working on #PewPew FeatherWing as an alternative platform, but at some point I started wondering if it’s really impossible to do it on the micro:bit.
When the most recent version of micropython got the ability to use any pins for I2C, I realized that I can finally connect a display easily. I could use a HT16K33 and a 8×8 LED matrix like on the PewPew, but I decided to try something else — a monochrome OLED display, similar to the one used on many Arduino-based game consoles.
From the Pluxx’s Magitech Golem Parts Emporium blog:
This is a breakout board for the Intersil ISL12022M real-time clock, with optional I²C pull-ups and a CR1225 backup battery. The circuit is based on the design recommended by Intersil, with a few tweaks. It’s the second board I’ve designed so far.

nickjkl created this breakout board to free up some breadboard space:
contains two I2C temperature sensors: a TC74 and a DS1631 because only one temperature sensor is never enough
KiCad design files and MSP430 Energia sketch example are available on GitHub:
I put together an I2C interface board for these displays based on a design by Adafruit, using a Holtek HT16K33 RAM Mapping 16*8 LED Controller Driver chip.
A nice feature of this chip is a dimming command that provides display dimming in 1/16 increments.
