Introduction[edit | edit source]
BORA Lite requires a dedicated adapter to be plugged to the BoraXEVB carrier board. This adapter:
- provides the SODIMM socket for the BORA Lite SOM
- provides the following additional features:
- microSD slot (for SD boot)
- JTAG connector
- CAN traslator for testing the CAN bus on BoraXEVB
- routes the signals from the BORA Lite pins to the BoraXEVB mating connectors
The following images show the top and bottom views of the BoraLite Adapter:
Connectors' pinout[edit | edit source]
J1 - SODIMM connector[edit | edit source]
J1 is a TE Connectivity 204-pin SODIMM socket. The pinout matches the Axel Lite pinout.
J4, J5, J6 - BoraXEVB mating connectors[edit | edit source]
J4, J5 and J6 are Hirose FX8C-140S-SV connectors that match the BoraXEVB SOM connectors' pinout.
J2 - JTAG[edit | edit source]
J2 is a SAMTEC FSI-110-03-G-S connector. The following table reports the connector's pinout:
| Pin# | Pin name | Function | Notes |
|---|---|---|---|
| 1 | DGND | - | - |
| 2 | JTAG_TCK | - | - |
| 3 | JTAG_TMS | - | - |
| 4 | JTAG_TDO | - | - |

CAN[edit | edit source]
Pins IO_L6P_T0_34 and IO_L19P_T3_34 can be used as CAN_TX and CAN_RX for the CAN0 interface. The BoraLite adapter provide the SN65HVD232 CAN bus transceiver required for proper CAN bus bus interface.
The CAN_L and CAN_H translated signals are routed to the J5.103 and J5.105 connector pins on BoraXEVB.
