BORA Lite Adapter[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 | - | - |
| 5 | JTAG_TDI | - | - |
| 6 | FPGA_INIT_B | - | - |
| 7 | FPGA_PROGRAM_B | - | - |
| 8 | FPGA_DONE | - | - |
| 9 | D.N.C. | - | - |
| 10 | 3V3 | - | - |
Routing options[edit | edit source]
This table helps to map Bora Lite's signals when it is mated with the BoraXEVB carrier board. That table assumes that the adapter is populated according to the default mounting option, which is illustrated in the schematics available here.
At the adapter level, other mounting options are available, however. Please refer to the schematics for more details.
CAN bus[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.
