The No Overhang Two Channel boards made for Speeduino share the features below
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
- Arduino MEGA 2560 shield board
|
||
|
|
- Same size as the Arduino
|
||
|
|
- 2 injector output channels
|
||
|
|
- 2 coil output channels
|
||
|
|
- Dedicated tachometer output
|
||
|
|
- 4 medium/high current outputs (idle, boost, VVT, fuel pump, fan, etc)
|
||
|
|
- IAT, CLT, TPS, and O2 inputs (protected)
|
||
|
|
- On-board MAP sensor
|
||
|
|
- Stepper idle control through board mounted DRV8825 accessory PCB
|
||
|
|
- VR conditioning through board mounted VR conditioner accessory PCB
|
||
|
|
|
||
|
|
Like the official Speeduino boards, the NO2C requires igniter driven coils and a conditioner for crank/cam signals that aren't 5v square-wave. The board is designed to accept the official Speeduino conditioner board for signals that do not meet the requirements.
|
||
|
|
|
||
|
|
NO2C v0.1.x
|
||
|
|
-----------
|
||
|
|
|
||
|
|
Uses the AMP MTA-100 or Molex KK100/KK254 connector system and through hole components
|
||
|
|
|
||
|
|
### v0.1.0
|
||
|
|
|
||
|
|
- Had flaws which caused the Arduino USB connector to interfere with the boards solder pads
|
||
|
|
- lacked tachometer output
|
||
|
|
- was never released
|
||
|
|
|
||
|
|
### v0.1.1
|
||
|
|
|
||
|
|
- corrected the issue mentioned above
|
||
|
|
- added tachometer output
|
||
|
|
|
||
|
|
NO2C v0.2.x
|
||
|
|
-----------
|
||
|
|
|
||
|
|
Uses the Molex Micro-Fit 3.0 connector system and through hole components. The Micro-Fit connector is used as a computer power connector and there are several manufacturers, it's known generically as 3mm connector.

|
||
|
|
|
||
|
|
### v0.2.0
|
||
|
|
|
||
|
|
- Added pass through pinholes around the edge for daughter board expansion
|
||
|
|
- Increased size of resistor footprints making it easier to find usable resistors and/or use precision resistors for all voltage dividers
|
||
|
|
- Increased pitch of 1uf caps (see above)
|
||
|
|
- Added launch control input
|
||
|
|
|
||
|
|
### v0.2.1
|
||
|
|
|
||
|
|
- Improved silk screen
|
||
|
|
- All MOSFET outputs (injector and auxiliary) have the same gate connection to the Arduino MEGA
|
||
|
|
- VR signals are routed straight into the conditioner
|
||
|
|
- MAP sensor location accepts either though-hole or SMD part
|
||
|
|
- Other routing and placement adjustments (R10 and R11 are flipped)
|
||
|
|
|
||
|
|
### v0.2.2
|
||
|
|
|
||
|
|
- Moved C20 from the edge of the board, it has always bothered me there
|
||
|
|
- Added Serial0/Bluetooth header
|
||
|
|
- Other routing and placement adjustments
|
||
|
|
|
||
|
|
### vC1
|
||
|
|
|
||
|
|
- Traditional reset protection removed in favor of a jumper and resistor to hold the reset pin high
|
||
|
|
- Routing and placement adjustments
|
||
|
|
- Version style changed to bring inline with other projects and due to required BOM change compared to v0.2.x
|
||
|

NO2C DB
|
||
|
|
-------
|
||
|
|
|
||
|
|
A daughter board that stacks on top of the NO2C v0.2.x and vCx boards to add the features below. The daughter boards are hybrid surface mount/through hole, see features below for which parts are through hole.
|
||
|
|
|
||
|
|
### DB1 (Scraped)
|
||
|
|
|
||
|
|
Makes it easy to add additional general outputs, and can be populated to add all the features below.
|
||
|
|
|
||
|
|
- 4 low current outputs (through hole)
|
||
|
|
- 2 general digital inputs (protected)
|
||
|
|
- 1 analog input (protected)
|
||
|
|
- Flex-fuel input (protected)
|
||
|
|
- Barometric pressure sensor (provides constant correction vs power on base)
|
||
|
|
|
||
|
|
### DB2
|
||
|
|
|
||
|
|
Makes it easy to add additional coil outputs, and can be populated to add all the features below.
|
||
|
|
|
||
|
|
- 2 additional coil output channels (through hole)
|
||
|
|
- 4 low current outputs
|
||
|
|
- 2 general digital inputs (protected)
|
||
|
|
- 1 analog input (protected)
|
||
|
|
- Flex-fuel input (protected)
|
||
|
|
- Barometric pressure sensor (provides constant correction vs power on base)
|
||
|
|

With the low current outputs you could reconfigure two of the medium/high current outputs on the NO2C to act as injector drivers. To do this you will have to make minor changes to the firmware before programming the Arduino.
