+
+## Overview
+
+The [SparkFun MicroMod](https://www.sparkfun.com/micromod) ecosystem uses an M.2
+edge connector to pair processor boards with function boards (carrier boards). This
+tutorial shows how to design a MicroMod carrier board using tscircuit.
+
+## The MicroMod M.2 Connector
+
+The MicroMod connector is a standard M.2 Key M edge connector with 75 pins.
+
+### Key Pin Groups
+
+| Pin Group | Pins | Description |
+|-----------|------|-------------|
+| Power | 3.3V, V_USB | Power supply pins |
+| I2C | SDA, SCL | I2C bus (Qwiic compatible) |
+| SPI | COPI, CIPO, SCK, CS | SPI bus |
+| UART | TX, RX | Serial communication |
+| ADC | A0-A5 | Analog inputs |
+| GPIO | D0-D5 | Digital I/O |
+
+## Basic M.2 Connector Setup

+  <board routingDisabled>
+    <connector name="M2" standard="m2" pcbX={0} pcbY={0} />
+  </board>
+`}
+/>

+  </board>
+`}
