Pinout
All E1M Edge AI modules use a standard SODIMM (Small Outline Dual Inline Memory Module) edge connector for interfacing with carrier boards. This page documents the connector pinout and signal assignments.
SODIMM Connector
The E1M modules use a 200-pin SODIMM connector, providing a high-density, reliable, and low-cost interconnect that is widely available from multiple connector manufacturers.

Signal Groups
The SODIMM connector carries the following signal groups:
Power
- VCC_3V3 -- 3.3V main power supply
- VCC_1V8 -- 1.8V I/O power supply
- GND -- Ground reference (multiple pins)
Communication Interfaces
- SPI -- Up to 2 SPI buses
- I2C -- Up to 2 I2C buses
- UART -- Up to 3 UART channels
- USB -- USB 2.0 / USB 3.0
High-Speed Interfaces
- Ethernet -- RGMII / RMII signals
- MIPI CSI-2 -- Camera serial interface
- MIPI DSI -- Display serial interface
GPIO
General-purpose I/O pins are multiplexed with alternate functions. See the ALP SDK GPIO API documentation for configuration details.
