This development board sports a fast Raspberry Pi RP2040 controller with 2MB of storage and 264 KB RAM. What makes this particular development special however, is the integrated 0.42" OLED display with a 40x70 pixel resolution. There is also an RGB LED on top of the board, as well as a QWIIC (I2C) connector on the bottom of the board that you can use with a wide range of add-ons.

Note: keep in mind, this is not a drop-in replacement for boards that are designed for a Pro-Micro (compatible) controller. Using this controller on a board that it was not designed for, could potentially lead to a damaged board, controller or both.
Note: this controller was designed to be similar to the XIAO controllers dimensionally. However, their appear to be slightly wider by about 1mm compared to the the XIAO controllers. If you assemble the sockets and pins to the controller before soldering to main pcb, they will fit PCBs intended for XIAO controllers just fine. If you're desiging a board around this controller however, either use larger (oval) holes or wider spaced rows of pinheaders..
