| ######################### |
| |
| Overview |
| ******** |
| |
| The SparkFun Pro Micro RP2040 is a small, low-cost, versatile board from |
| SparkFun. It is equipped with an RP2040 SoC, an on-board WS2812 addressable |
| LED, a USB connector, and a Qwiic connector. The USB bootloader allows it |
| to be flashed without any adapter, in a drag-and-drop manner. |
| |
| Hardware |
| ******** |
| - Dual core Arm Cortex-M0+ processor running up to 133MHz |
| - 264KB on-chip SRAM |
| - 16MB on-board QSPI flash with XIP capabilities |
| - 18 GPIO pins |
| - 4 Analog inputs |
| - 1 UART peripherals |
| - 1 SPI controllers |
| - 2 I2C controllers (one via Qwiic connector) |
| - 16 PWM channels |
| - USB 1.1 controller (host/device) |
| - 8 Programmable I/O (PIO) for custom peripherals |
| - On-board RGB LED |
| - 1 Watchdog timer peripheral |

| Pin Mapping |
| =========== |
| |
| The peripherals of the RP2040 SoC can be routed to various pins on the board. |
| The configuration of these routes can be modified through DTS. Please refer to |
| the datasheet to see the possible routings for each peripheral. |
| |
| Default Zephyr Peripheral Mapping: |

| - UART0_RX : P1 |
| - I2C1_SDA : P2 |
| - I2C1_SCL : P3 |
| - SPI0_RX : P20 |
| - SPI0_SCK : P18 |

| Programming and Debugging |
| ************************* |
| |
| Flashing |
| ======== |
| |
| Using UF2 |
| --------- |
| |
| The Pro Micro board does make the SWD pins available on pads on the |
| underside of the board. You can solder to these pins, and use a JTag |
| debugger. You can also flash the SparkFun ProMicro RP2040 with a UF2 file. |
| By default, building an app for this board will generate a |
| `build/zephyr/zephyr.uf2` file. If the Pro Micro RP2040 is powered on with |
| the `BOOTSEL` button pressed, it will appear on the host as a mass storage |
| device. The UF2 file should be copied to the device, which will |
| flash the Pro Micro RP2040. |
