AMS - CANBus - RGB - Nchannel is an open-source printed circuit board by TJLTM, from the TJLTM/Automotive-Monitoring-System-CANBus-Sensor repository on GitHub. It is a 2-layer board of 72.9 × 71.1 mm with 59 parts on 64 nets, routed with 513 tracks and 27 vias.
It is built around the ATMEGA328P-PU, MCP2551-I/SN-HG and IRF9Z34NPBF, with the BZX79C10, PESD5V0L2UU,115-ES and TS02-66-160-BK-260-LCR-D among its other parts. Its parts include 21 resistors, 10 transistors, 8 capacitors, 5 connectors and 4 ICs. It belongs with the interfaces and adapters and lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.
What is this? --- when working on my AMS solution i kept putting more and more stuff into a single box and everytime i needed to make a change it was $200 for a board that may or may not work so i decided to make it easier on myself to split the sensors up so that it isn't a bespoke solution for a single car application.
these are the sensor hardware designs that match up with https://github.com/TJLTM/Automotive-Monitoring-System-CANBus-Sensor-FW repo so that i can keep the Hardware designs over here and the FW over there. mostly just so i'm not in some weird state where i'm working on a FW for one thing and the hardware for another and get into a screwed up merge situation. this has happened before in my other projects.
If you look at the other repo you'll see i've made provisions for the following sensors
The other boards ahve the hardware built on to the boards since those require some type of special sensor
Vacuum sensor This one is something that i've been working on for a while since there aren't many direct vacuum sensors out there and it took me a while to figure out this design as most vacuum sensors or MAPs so a bit of math to do it. They take the Barometric pressure and then making a few assumptions use the differential to standard atmospherical pressure to give you the vacuum. The design i am using is a direct measurement of the vacuum via the honeywell sensor. Yes it's expensive to build. In fact it costs more to make one of those then all the others combined.
RPM sensor this one is a straight foreward design and i may make it an add on module for the ADC since really it's just a Freq to Voltage Sensor
The I/O box... That one i'm making it a standard 8 in and 8 out setup. can be made to i don't know.... hook into power window units in older cars that can then be remotely controlled or in my case add power windows to some cars.
LED General 3 Channel RGB leds can be driven off of this I'm making it 4 channel since i have the space for it. It can either be high or low side switching depending on your application. this is using the 0-255 PWM output of the AVR
I'm using my other design for power https://github.com/TJLTM/LM2670SX-Carrier but if you don't like it. BYOPS

From the TJLTM/Automotive-Monitoring-System-CANBus-Sensor repository on GitHub, at the commit this page was made from: the board is AMS - CANBus - RGB - Nchannel/AMS - CANBus - RGB - Nchannel.kicad_pcb and its schematic AMS - CANBus - RGB - Nchannel/AMS - CANBus - RGB - Nchannel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
