Connectors and Pinout Table

This chapter contains the pinout description of the Bora module, grouped in six tables (two – odd and even pins – for each connector) that report the pin mapping of the three 140-pin Bora connectors.

Connectors description

In the following table are described the interface connectors on Bora SOM:

Connector name	Connector Type	Notes	Carrier board counterpart
J1, J2, J3	Hirose FX8C-140S-SV 3x140 pins 0.6mm pitch connectors		Hirose FX8C-140P-SV<x> where <x> stays for: empty = 5 mm board-to-board height 1 = 6 mm board-to-board height 2 = 7 mm board-to-board height 4 = 9 mm board-to-board height 6 = 11 mm board-to-board height

The dedicated carrier board must mount the mating connector and connect the desired peripheral interfaces according to BORA pinout specifications. See the images below for reference:

BORA BOTTOM view - J1, J2, J3 connectors (pins 1-139, 2-140)

Pinout table naming conventions

Each row in the pinout tables contains the following information:

Pin	Reference to the connector pin
Pin Name	Pin (signal) name on the AxelLite connectors
Internal connections	Connections to the components CPU.<x> : pin connected to CPU pad named <x> CAN.<x> : pin connected to the CAN transceiver (TI SN65HVD232) LAN.<x> : pin connected to the LAN PHY (Microchip KSZ9031) USB.<x>: pin connected to the USB PHY (Microchip USB3317) NOR.<x>: pin connected to the NOR flash NAND.<x>: pin connected to the NAND flash IO_L<x>: pin connected to PL (FPGA) MTR: pin connected to voltage monitors MON_<x>: pin for external voltage monitoring
Ball/pin #	Component ball/pin number connected to signal
Voltage	I/O voltage levels 1.8V 3.3V U.D. = User Defined
Type	Pin type: I = Input O = Output D = Differential Z = High impedance S = Power supply voltage G = Ground A = Analog signal A/G = Analog Ground
Notes	Remarks on special pin characteristics
