SparkFun MicroMod Main Board - Single

The SparkFun MicroMod Main Board - Single is a unique carrier board that provides an easy way to interface a MicroMod Processor Board with a single MicroMod Function Board. Thanks to the M.2 MicroMod connector, assembling your boards is a quick and straightforward process. The board is equipped with a USB-C connector for power and programming, two buttons for reset and boot, a 2A resettable fuse, a 3.3V/1A voltage regulator, a 2-pin JST connector, a single cell LiPo MCP73831 charge IC, three status LEDs, a microSD card socket, and two Qwiic connectors.

The MicroMod Main Board is perfect for advanced users who want to measure the current consumption for low power testing. It also includes a jumper for bypassing the fuse. For those who want to take their application remote, a 2-pin JST connector and a single cell LiPo MCP73831 charge IC are included. The charge IC is set to a rate of 500mA. The board also contains three status LEDs for power and charging, and a microSD card socket for data logging. The inclusion of two Qwiic connectors makes it easy to add Qwiic enabled I²C devices to your projects.

The MicroMod ecosystem, of which this board is a part, is a modular interface system that allows for easy swapping of processors and function boards. This means you can customize your carrier board to suit the specific needs of your project by choosing a compatible processor. Please note that the MicroMod Processor and Function Board are not included with the MicroMod Main Board and will need to be purchased separately.

The package includes the MicroMod Main Board - Single and three Phillips #0 M2.5x3mm Screws. The board features an input voltage range of 5V via the USB C Connector and ~3.7V to 4.2V via the LiPo Battery Connector. It also has a built-in Resettable PTC Fuse rated at 5V/2A, an AP7361C 3.3V Voltage Regulator rated at 1A, and an Integrated MCP73831 Single Cell LiPo Charge Circuit with adjustable charge rates via DIP Switch. The board also has several ports, buttons, LEDs, and jumpers for various functions and uses.
