SparkFun MicroMod mikroBUS Carrier Board

Added to your shopping cart

The SparkFun MicroMod mikroBUS Carrier Board takes advantage of the MicroMod, Qwiic, and mikroBUS™ ecosystems making it easy to rapidly prototype with each of them, combined. The MicroMod M.2 socket and mikroBUS 8-pin header provide users the freedom to experiment with any Processor Board in the MicroMod ecosystem and any Click board in the mikroBUS ecosystem, respectively. This board also features two Qwiic connectors to seamlessly integrate hundreds of Qwiic sensors and accessories into your project.

The mikroBUS socket comprises a pair of 8-pin female headers with a standardized pin configuration. The pins consist of three groups of communications pins (SPI, UART and I2C), six additional pins (PWM, Interrupt, Analog input, Reset and Chip select), and two power groups (3.3V and 5V).

While a modern USB-C connector makes programming easy, the Carrier Board is also equipped with a MCP73831 Single-Cell Lithium-Ion/Lithium-Polymer Charge IC so you can charge an attached single-cell LiPo battery. The charge IC receives power from the USB connection and can source up to 450mA to charge an attached battery.

Note: Please be aware that MicroMod Processors, Qwiic boards and cables, and Click boards are not included with the MicroMod mikroBUS Carrier Board. These parts will need to be purchased separately. At this time only the STM32 Processor Board is fully compatible with mikroBUS Carrier board.

MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

Getting Started with Necto Studio

March 4, 2022

Necto Studio is a user friendly development environment for users looking to get started with MikroElektronika's MIKROE products.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

1 Electrical Prototyping

Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

    Are you guys NOT including the M.2 machine screw any longer with the MicroMod boards? Picked up 3 of these mikroBus carrier boards and none of them had the M2.5x3mm included (

    If this isn't an oversight, I would suggest including in the note section these screws now require an additional purchase.

    BTW, love the move, even though on its face it seems the two companies compete on a variety of break out boards and sensors. But having a way to use my Click boards with SFE products is really consumer friendly - thank you!

    Would love to see some collaboration on the Mikroe MCU cards - either SFE making some MCU boards, or carrier boards to support Mikroe's existing line up.

    • These boards should 100% have an M.2 machine screw included. You can expect communication from us about a free set of screws soon. We'll be working to correct this on any additional orders ASAP.

      We are extremely excited to combine the forces of Click/mikroBUS, Qwiic, and MicroMod together and we hope to continue expanding them into the future!

    I just received the mikroBUS Starter Kit KIT-19935 last week (July 13, 2022) and the screw was missing in my kit, too. Batch #150893 on the label on the box.

        Thanks for the quick reply. I found the screw size I need and have already ordered them.
