One of the challenges is how to visualize ECU in BSA. The symbols below are highly exprimental and mostly added to drive the discussion about how to do this in a system diagram if you have an ECU with sub-modules. How do I visualize this in a diagram creating code for that ECU? The “PWM…
RL have a tendency to hit in with to much work sometimes reducing the amount of time I can use on these projects, but I finally decided to do a push on BSA again and complete print & copy functions. Below is some pictures – the first shows a mock-up diagram with all symbols on…
This first picture show an open box with Ethernet + 5 Add-On modules. Screw holes fit perfect, cables line up and it was a dream to assemble one box with full content. The mechanics of this project is a success. Cloed box with M12’s and MX23 sticking out below. I only need minor adjustments on…
The 3 x Analogue module below will get some siblings, The current module is experimental as I need to play around with analogue input a bit and see what I can achieve, The target is vibration sensors this time that is ok with 0-5V input. But, the module is so much more capable than this…
An old modul to the left and two new moduls to the right – I thought my old module was small… This is the first run on this series so the main issue right now is mechanical design + correcting bugs – don’t worry, I have found some already – mechanical ones, but that is…
A quick draft of a 8 Digital Input Channel module allowing 24V or 5V selectable per channel. I will receive the first batch of PCB’s tomorrow so fun will start, but I fancied having a look at a 8 channel digital input where I can select between 5V and 24V levels per channel.
With a main board and up to 8 sub-modules I need to design ipc communication between them. The sub-module uses a fast, exclusive serial port 1:1, but we also need to take into account Ethernet, RS485 and CAN as media. The essense of easyIPC is that I want a protocol where I don’t care about…
The main reason I avoid components on the back side is because I want to use this for heatsink and connect a thermal pad between the PCB’s and the aluminium box – using the box itself + possible external heatsinks to cool down content inside. So far it is only the 8 x PWM module…
I have made a few PCB’s that will create a modular, waterproof ECU, so lets walk through the ones that will be ordered now. I will make more modules later, but I am stretching my luck aleady. This main board and modules are not entirely new as I created a series of PCB’s before where…
This was a bit tight to route because it is a lot on very little space and a lot of isolation areas and hole through components. The main challenge is however that I ran out of pins on the MCU. The routing straegi is free lines on top, ground, 3.V, horisontal layer, ground, vertical layer…
