Deucalion - son of Prometheus, also a compact ECU shield!

Post by andreika » Sat Feb 23, 2019 4:28 pm

Hi there!

Let me introduce our new ECU board - Deucalion!

About Deucalion...

Deucalion is the son of Prometheus.
An innovative easy-to-build ECU shield on rusEFI firmware.
Caution! This is an experimental project at a very early development stage! More info to come...

Main ideas behind Deucalion:
  1. Only bare essentials on-board with as few components as possible
  2. Minimum soldering time should be required for board assembly (one-sided component layout!)
  3. Compatible with Bosch M7.9.7/ME7.8.8 ECU pinouts & connectors
  4. Simple 2 layer board less than 100x100 mm ($10 for 10 boards in china)
Main components:
  1. STM32-mini brain board as a main cpu ($11 on ebay)
  2. Kinetis MKE1xF as analog/trigger input software controller ($7)
  3. TLE6240GP for injector and low-side outputs, up to 16 total ($2 on aliexpress)
...And a couple of dozens of small components and basically that's all! Under $50 components total! As easy as apple pie :)

* * *

Features:
  • * 4 sequential ignition & injector outputs including built-in ignition drivers (and up to 6 outputs can be easily extended on the same board!)
    * 99.9% PnP compatible with Bosch M7.9.7, ME7.8.8, Yanvar7.2 (Январь7.2), Mikas10.3
    * 20 (!) configurable analog/digital inputs including 6 universal trigger inputs (for VR trigger sensors, Knock detection, Ion Sense etc.)
    * ...
All project documentation (including schematics & gerbers) will be available soon.
More photos and description will follow.
Stay tuned! 8-)


Thank you for your attention,
andreika.

Do I see dual connector footprint? A lot of ingenuity on this board!

No, of course not! It's a triple connector footprint! :lol:

So is that a JimStim2 :)

Great video, and great progress. Looks like it has come a long way.

HS-mode 168 MHz, which is preferable for realtime multichannel analog signal processing (trigger + knock/ion sense).

The idea behind KE1xF Kinetis in Deucalion is a combination of several features:
1) 5V-compatible inputs/outputs;
2) High-speed 168 MHz clock - so we have STM32F4-comparable performance guaranteed (most other 5V NXP chips have lesser freq);
3) 3x high-speed hardware analog comparators + 3x ADCs - very useful for software analog signal processing (level detectors etc.);
4) High drive output pins (~20mA) suitable for direct driving of logical COPs;

We now have https://github.com/rusefi/rusefi/blob/m ... inetis.bat

Note the cool four channel TVS Diode Arrays DT1042-04SO SOT-26 about $0.45 each available on both Mouser and Digikey.

Note the cool tiny PCB jumpers between bottom huge connector and lower row of resistor arrays to configure pull-up / pull-down.

I likes the diodes array.

I also read this as Delicious. I also think yum when I read it.
