Nexgen: Dual Protocol Converter: Ethernet - 4

4 Mar 2023

Well here were are in part 4 of building my dual protocol converter from 2 Raspberry Pi Model 1 this will fit into one of my plastic ATR (shoe) boxes.

To power the pi(s), I'm duplicating the USB power circuit with two outputs. The power will be provided to P5-1 and P5-7 for the ground. I will also add a 5vdc regulator between the power from my Jack and the auxiliary power board.
The layout will be straightforward, the pies will be accessible by the front panel. This will enable me to segregate the two pies to the right and left corners.
Due to the rounded corners, I will have to mount them 1/2" from the two sides. In the center, I will mount the Rj45 breakout board, for the CANaerospace access. Also, I need to mount two (2) CAN to SPI modules, hopefully, I can mount them on top of each other.

Function	RPI-P1	Module
5v DC	P5-1	Vcc
Ground	P5-7	GND
Interrupt		INT
SPI_CE1_N	P1-26
SPI_CE0_N	P1-24
SPI_MISO	P1-21	MISO
SPI_MOSI	P1-19	MOSI
SPI_SCLK	P1-23	SCK
