Introducing the Glyph Mini RP2040, a compact and high-performance microcontroller development board powered by the powerful RP2040 chip. Ideal for IoT projects, robotics, sensors, and advanced embedded systems, the Glyph Mini offers flexibility, speed, and modern connectivity—making it a perfect platform for innovation and rapid prototyping.

### Features

* **Dimensions**: Measures 18mm x 23.5mm without headers soldered in
* **Processor**: Raspberry Pi RP2040 32-bit dual-core ARM Cortex-M0+ processor running up to 133 MHz @ 3.3V logic and power
* **RAM**: 264 KB on-chip SRAM
* **Flash Memory**: 8 MB on-board SPI Flash
* **GPIO**: 20 multi-function GPIO pins

All the important peripherals, labeled for easy access.

### Power Management

* **USB Type-C Connector** for power, programming, and serial debugging
* **LDO Regulator** with up to 800mA peak output current

<Note>
  This board lacks on-board battery protection, charging circuitry, or hot-swap logic. Battery connection requires external protection/switching.
</Note>

### Additional Features

* **On-board Status LED** (Connected to GPIO16)
* **BOOT and RESET buttons** for easy firmware access and programming

### Bootloader and Programming

The Glyph Mini RP2040 comes with a built-in USB UF2 bootloader, making firmware uploads simple and hassle-free. For first-time use, hold down the BOOT button while connecting the board to your computer via USB (or press RESET while holding BOOT). It will appear as a removable mass storage device, allowing you to drag and drop your `.uf2` firmware file.

### Connectivity

The RP2040 is a powerful microcontroller ideal for high-speed local processing and I/O. For wireless applications, it easily supports external modules such as:

* **Bluetooth**: HC-05 / HC-06
* **Wi-Fi**: ESP8266 / ESP32 (AT commands or co-processor)
* **Long Range**: nRF24L01, LoRa, or XBee

With multiple SPI, I2C, and UART interfaces, integrating these modules is straightforward and efficient.

### Development Support

The Glyph Mini RP2040 is supported by a robust ecosystem of development environments:

* **MicroPython** (Official RP2040 support)
* **CircuitPython** (Official Adafruit support)
* **Arduino IDE**
* **C/C++ (Pico SDK)** (Full support via VSCode)

</div>

With extensive library support, strong community backing, and rich documentation, getting started with the Glyph Mini RP2040 is simple and efficient for both beginners and advanced developers.

### Memory and Storage

The RP2040 features 264 KB of on-chip SRAM for fast data processing. In addition, it includes 8 MB of on-board SPI Flash shared between code, file storage (LittleFS), and application data.

### RP2040 Chip Features

* **Dual-core ARM Cortex-M0+**: Deterministic and high-performance processing.
* **Up to 133 MHz**: Flexible PLL allows for overclocking if needed.
* **Programmable I/O (PIO)**: Dedicated state machines for custom peripheral protocol handling.
* **Low Power Modes**: Capable of achieving sleep currents around 2 mA.
