Align the keyed edge connector, fasten the boards with screws, and you can swap processors or functions to suit your project.The board provides USB-C for power and programming, reset and boot buttons, a 2x5 SWD breakout, power regulation, a resettable fuse, and useful jumpers for measurement and low-power testing. For portable projects, it includes a 2-pin JST LiPo connector and an MCP73831 single-cell charge circuit.For expansion and logging, the board includes two Qwiic I2C connectors with built-in pull-up resistors, a microSD card socket, status LEDs for power and charging, and jumpers to disable selected indicators or circuitry. SparkFun hardware documentation and a MicroMod Main Board getting-started guide are available for setup.Features:MicroMod carrier: Interfaces a MicroMod Processor Board with a single MicroMod Function Board.M.2 MicroMod connection: Match up the key on your board's beveled edge connector to the key on the M.2 connector and secure the boards with screws.USB-C: USB-C connector for power and programming the Processor Board.USB C shield: Jumper on the back of the board to isolate the USB C's shield pin.Buttons: Reset and boot buttons are populated on the board.SWD: Processor Board pins are broken out as 2x5 SWD pins.Protection: Includes a 2A resettable fuse.Power regulation: Includes a 3.3V/1A voltage regulator.Qwiic power: Includes a second 3.3V/500mA voltage regulator to power Qwiic-enabled devices.Low-power testing: PTH jumpers allow advanced users to bypass the fuse and measure current consumption on the 5V and 3.3V lines.Battery operation: Includes a 2-pin JST connector and a single-cell LiPo MCP73831 charge IC set to a charge rate of 500mA.Status LEDs: Four status LEDs are available for power and charging.LED jumpers: Status LEDs can be disabled through jumpers.Data logging: Includes a microSD card socket.microSD control: The microSD socket can be disabled through the I/O pins.Qwiic expansion: Two Qwiic connectors are populated on the board with built-in pull-up resistors.Revision change: Rotate silkscreen for the connectors and a majority of the labels.Revision change: Add TVS diodes for ESD protection on the USB pins.Revision change: Add SHLD jumper to isolate the USB Type C connector's shield pin.Revision change: Add a 5V MEAS PTH jumper as a measurement for 5V.Revision change: Remove the 500mA/100mA selector for the LiPo charge circuit. The board now charges at a default rate of 500mA only.Revision change: Add a DIVIDER jumper to remove the resistor divider that is connected to processor's "BATT_VIN/3" pin for low power applications.Revision change: Add a dedicated 3.3V/500mA voltage regulator for the Qwiic port.Revision change: Add GPIO control of 3.3V voltage regulator (I2C_SCL1-Processor).Revision change: Add a LED for the 3.3V Qwiic port with a QWIIC LED jumper to disable.Revision change: Add a transistor to disable power to the microSD socket (can be controlled using I2C_SCL1-Processor).Revision change: Add multiplexed primary UART pins to send serial data to Function Board(s).Revision change: Add PTH pins for multiplexed UART.Revision change: Move PWR_EN0 from SDIO_Data2_Processor to PWM1.Revision change: Add two 2.2kΩ I2C pull-ups to the primary I2C pins with jumpers (I2C) to disable.Specifications:Input Voltage Range: 5V via USB C ConnectorInput Voltage Range: ~3.7V to 4.2V via LiPo Battery ConnectorBuilt-in Resettable PTC Fuse: Rated 5V/2AVoltage Regulator: AP7361C 3.3V/1AVoltage Regulator: AP7347DQ 3.3V/500mA Voltage Regulator (for Qwiic-Enabled Devices)LiPo Charge Circuit: Integrated MCP73831 Single Cell LiPo Charge CircuitLiPo Charge Current: 500mAPort: 1x USB Type C ConnectorPort: 1x 2-Pin JST ConnectorM.2 Connector: 1x MicroMod Processor BoardM.2 Connector: 1x MicroMod Function BoardQwiic Enabled I2C: 2x Qwiic Enabled I2CMicroSD Card Socket: 1x MicroSD Card SocketSWD Header: 1x SWD 2x5 HeaderUART: Built-in MUX for UART1Button: 1x ResetButton: 1x BootLED: 1x VINLED: 1x 3.3VLED: 1x Qwiic 3.3VLED: 1x CHGPlated Through Hole: GNDPlated Through Hole: SELPlated Through Hole: TXOPlated Through Hole: RXIPlated Through Hole: RSTPlated Through Hole: 5V (MEAS)Plated Through Hole: VBATPlated Through Hole: 3.3V (MEAS)Jumper: USB SHLDJumper: 5V MEASJumper: 3.3V MEASJumper: PTCJumper: 3.3V ENJumper: VIN LEDJumper: 3.3V LEDJumper: Qwiic 3.3V LEDJumper: I2CJumper: Battery Voltage DividerBoard Dimensions: 3.40" x 2.90"Note: a MicroMod Processor Board and MicroMod Function Board are not included and must be purchased separately. **Product Type:** MicroMod Carrier Board ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDfLwCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b2af9a28b199ca641961782a43eb4a62bcdf66d9/20748-DEV_SparkFun_MicroMod_Main_Board_Single_v21-01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDf7wCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--e1165556e45097444cca09141e21ca4dcc26e3bb/20748-DEV_SparkFun_MicroMod_Main_Board_Single_v21-02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDgrwCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a163bad3b0d331157fad9accb01084703e72cabb/20748-DEV_SparkFun_MicroMod_Main_Board_Single_v21-03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDhLwCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--2c2fffc2a4af64a3567f259b2bd586f237ce844e/Function_Board-_02.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
