Introduction[edit | edit source]
Axel Lite requires a dedicated adapter to be plugged to the AxelEVB-Lite carrier board. This adapter:
- provides the SODIMM socket for the AxelLite SOM
- provides the following additional features:
- microSD slot (for SD boot)
- JTAG connector
- dip-switch for boot mode selection
- routes the signals from the AxelLite pins to the AxelEVB-Lite mating connectors

Connectors' pinout[edit | edit source]
J6 - SODIMM connector[edit | edit source]
J6 is a TE Connectivity 204-pin SODIMM socket. The pinout matches the Axel Lite pinout.
J1, J2, J3 - AxelEVB-Lite mating connectors[edit | edit source]
J1, J2 and J3 are Hirose FX8C-140S-SV connectors that match the AxelEVB-Lite SOM connectors' pinout.
J4 - JTAG[edit | edit source]
J5 - MicroSD[edit | edit source]
The signals of the SD1 interface are routed to the J5 microSD memory card connector. The following table reports the connector's pinout:
| Pin# | Pin name | Function | Notes |
|---|---|---|---|
| 1 | SD1_DAT2 | DATA[2] | - |
| 2 | SD1_DAT3 | Card Detect/DATA[3] | - |
| 3 | SD1_CMD | CMD line | - |
| 4 | ADP_3.3V | Power Supply | - |
| 5 | SD1_CLK | Clock | - |
| 6, 9, 10, 11, 12 | DGND | - | - |
| 7 | SD1_DAT0 | DATA[0] | - |
| 8 | SD1_DAT1 | DATA[1] | - |
| 13 | ADP_3.3V | - | Pull up to 3.3V with 10K Ohm - |
