MicroMod Data Logging Carrier Board Hookup Guide
Introduction
The MicroMod Data Logging Carrier Board is similar the SparkFun Logomatic to offer users a dedicated data
logging board but adds the ability for you to pick a MicroMod Processor Board to customize it for your next data
logger project. The Data Logging Carrier board was designed specifically for low power control and sensor data
harvesting with the MicroMod ecosystem.
SparkFun MicroMod Data Logging Carrier Board
 DEV-16829
The Data Logging Carrier Board allows you to control power to both the Qwiic connector on the board as well as a
dedicated power pin for non-Qwiic peripherals such as serial UART or SPI devices so you can pick and choose
when to power the peripherals you are monitoring the data from. It also features a charging circuit for single-cell
Lithium-ion batteries along with an RTC battery-backup circuit to maintain power for a real-time clock circuit on
your Processor Board.
Required Materials
Like all of our MicroMod Carrier Boards, there is no processor included but instead you can plug in a Processor
Board of your choice to the MicroMod M.2 connector on the carrier. Below are a few options to choose for your
processor:

    Processor Board interacts with it and highlight a few unique features on the board. Common Components Most SparkFun MicroMod Carrier Boards will have some common components and all MicroMod Carrier Boards will have the keyed M.2 MicroMod Connector to plug your processor into. The photo and list below outline some of the components included on most SparkFun MicroMod Carrier Boards.
  • Page 5 RTC Backup Battery & Charge Circuit - 1mAh backup battery for the RTC for certain MicroMod Processor Boards . Receives charge voltage from 3.3V. microSD Slot - Insert a µSD card formatted to FAT32(?) here to log your data. Power Control Circuit The Data Logging Carrier Board features two 3.3V/600mA voltage regulators that have their Enable pins tied to I/O pins on an attached MicroMod Processor Board.
  • Page 6 Data Logging Connections Along with the Qwiic connector mentioned in the Common Components, the Data Logging Carrier Board breaks out several other pins to connect UART, SPI and other I/O devices. The primary SPI pins are netted to the µSD slot and a PTH header near the LiPo battery connector.

    Having trouble viewing the detail in either photo? Click on them for a larger view! Board Dimensions The MicroMod Data Logging Carrier Board measures 2.40" x 1.60" (60.96mm x 40.64mm) and has five mounting holes that fit a 4-40 screw. Take note of the mounting hole labeled "Qwiic Mount" above the µSD slot as it can work as single mount for a Qwiic breakout (or other sensor) or you can pair it with the outer mount in the "top-right"...

Note: There is technically no way to insert the processor backward since the key prevents it from mating with the M.2 connector.
