SparkFun RP2040 mikroBUS Starter Kit

The SparkFun RP2040 mikroBUS™ Starter Kit is designed to give you just what you need to start using the Click and Qwiic ecosystems side-by-side powered by Raspberry Pi! The core of this kit is designed around the [SparkFun RP2040 mikroBUS™ Development Board](https://www.sparkfun.com/products/18721), the [SparkFun Micro OLED Breakout (Qwiic)](https://www.sparkfun.com/products/14532), and the [MIKROE Weather Click](https://www.sparkfun.com/products/18823). Additionally, to connect everything together we also include a [100mm Qwiic Cable](https://www.sparkfun.com/products/17259), and a [USB A-C cable](https://www.sparkfun.com/products/14743)!

The SparkFun RP2040 mikroBUS™ Development Board is a low-cost, high performance platform with flexible digital interfaces featuring the Raspberry Pi Foundation\'s RP2040 microcontroller. Besides the Thing Plus or *Feather* PTH pin layout, the board also includes a microSD card slot, 16MB (128Mbit) flash memory, a JST single cell battery connector (with a charging circuit and fuel gauge sensor), an addressable WS2812 RGB LED, JTAG PTH pins, four (4-40 screw) mounting holes, our signature Qwiic connectors, and a mikroBUS™ socket.

The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. While the chip has a large amount of internal RAM, the board includes an additional 16MB of external QSPI flash memory to store program code. The RP2040 contains two ARM Cortex-M0+ processors (up to 133MHz) and features:

* 264kB of embedded SRAM in six banks
* 6 dedicated IO for SPI Flash (supporting XIP)
* 30 multifunction GPIO:
* Dedicated hardware for commonly used peripherals
* Programmable IO for extended peripheral support
* Four 12-bit ADC channels with internal temperature sensor (up to 0.5 MSa/s)
* USB 1.1 Host/Device functionality

For the mikroBUS™ socket we include the MIKROE Weather Click. MIKROE Weather Click carries BME280 integrated environmental unit from Bosch. It’s a sensor that detects humidity, pressure, and temperature, specifically designed for low current consumption and long-term stability. The click is designed to work on a 3.3V power supply. It communicates with the target microcontroller over SPI or I2C interface.

For the Qwiic port we include the SparkFun Micro OLED Breakout (Qwiic). The SparkFun Qwiic Micro OLED Breakout is a Qwiic-enabled version of our popular Micro OLED display! The small monochrome, blue-on-black OLED screen presents incredibly clear images for your viewing pleasure. It’s “micro,” but it still packs a punch --- the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next project and displaying diagnostic information without resorting to a serial output, all with the ease of use of our own Qwiic Connect System!

*The [SparkFun Qwiic Connect System](https://www.sparkfun.com/qwiic) is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.*
