METE HOCA Akana R1 is a user-friendly and compact development board designed to make STEM coding practical and enjoyable, built on Raspberry Pi's RP2040 microcontroller. What sets the Akana R1 apart from other boards is its built-in OLED display and user buttons.

The Akana R1 features a 1.3-inch I2C OLED display and a set of 4+2 user buttons arranged in a game controller format. These six buttons are equipped with a special debounce circuit to prevent unwanted multiple presses (button bouncing). The BOOTSEL and RESET buttons necessary for coding are also located on the top of the board.

The Akana R1 uses the RP2040 microcontroller developed by Raspberry Pi and has a USB Type-C connector for connecting to a computer. The USB connection is not only for coding but also allows the Akana R1 to function as a keyboard or game controller when connected to a computer.

The board's most important feature is the AkanaPort header connection. AkanaPort includes all the digital and analog pins of the RP2040, along with power connections. The colorful labels on the AkanaPort header help prevent connection errors and ensure easy usage. You can create your own "Akana Dock" using our KiCad design file. Check below.

For advanced users, the board also includes an I2C selection switch, enabling all I2C components on the board and AkanaPort to be switched to the desired I2C channel simultaneously.

On the front of the board, there are 2 LEDs, and on the back, there are 4 LEDs. The first LED on the front is marked with "ON" in the upper left corner, indicating that the board is powered. In the upper right corner, there is a built-in coding LED under user control, connected to the RP2040's GP25 pin. The four LEDs on the back, spread across the corners, are also connected to GP25, just like the user LED on the front.

The Akana R1 has everything you need to program the RP2040 microcontroller it is built upon. All you need to do is connect the board to your computer via a USB cable to start learning, experimenting, and having fun.

The Akana R1 can be programmed using Arduino IDE, MicroPython, or CircuitPython.
