The AM13E SoM is a 25.4 × 38.1 mm controller module built around the XAM13E23019GTPZ 100-pin MCU. U2 is the TCAN844DRBRQ1 CAN transceiver, and U3 switches bus termination. U4, U5 and U6 handle power selection, load switching and digital regulation.

Use these assembly views to find connectors and components. Reference labels match the KiCad board files. Select an image for a closer look.
Top looks down at F.Cu. Bottom looks directly at B.Cu after turning the board left-to-right, keeping the same top edge up. Left and right therefore reverse; the bottom drawing is not a view through the board. Use the connector pad table for electrical assignments.
| Connector | Purpose |
|---|---|
| J1 | Underside 100-pad LGA interface for a carrier |
| J2 | Eight-pin debug, UART, reset and boot row |
| J3 / J6 | J3 left / J6 right in the top view; 12 pins each |
| J4 | Qwiic I²C connection |
| J5 | CAN bus and power |
The nominal PCB outline has a southwest relief. Use the KiCad board outline when checking mating geometry and assembly clearance.
Mechanical integration
J1 uses 1.27 mm pitch with 0.6 mm pads. The two expansion-row origins are 22.86 mm apart. Successive row pad centers advance by 2.54 mm, with alternating lateral stagger. Match the complete 12-pin row geometry when designing a mating connector.
Allow space for connectors, cables and assembled components as well as the bare PCB outline. For a soldered carrier, the assembly notes explain the module stencil and mating-array paste arrangement. Keep the debug row accessible if you expect to program or service the module after installation.
