MAP-board 1.0
Important: the pinout of internal sensor can be found on GenBoard/Manual/Wiring/ManifoldAbsolutePressure
Pin1 (of the black SSC-male connector) is the leftmost on the above picture (you can verify the pin numbers printed on the female).
The packaged sensor is casted with epoxy, very durable, you can step on it or melt the external softer black part without damage to the internals.
The 400kPa version is recommended for > 130kPa (1.3bar, 18psi) boost. On the 12V, 400kPa version, there are some simple extras onboard, like
- regulator (so it can be powered from 12V and there is a 5V output)
- thermometer (Temperature output)
You can tell the different versions by the number of actually present SSC pins (3/4/5).
Pinout of the 12V, 400kPa version - most popular
Note that populated this way, the supply has a wide range, and the 5V is output, not input. Applying 5V to the 5V output is not supported, it might damage the unit. Use the 5V version if you want to power something from 5V (max 50mA). This version has (all) 5 male pins (none missing).
| SSC pin | recommended color | signal | range | note |
| 1 | white | MAP output | 0 .. 4.8V | 20..400kPa |
| 2 | brown | GND | 0V | |
| 3 | red | 5V out | 5V | max 80mA. Useful for HALL, TPS, etc... |
| 4 | blue | temp out | 0.5 .. 4.5V | NTC, similar U(T) as CLT |
| 5 | grey | +12V in | 6.3 .. 16V |
Pinout of the 5V, 400kPa version
| SSC pin | recommended color | signal | range | note |
| 1 | white | MAP output | 0 .. 4.8V | 20..400kPa |
| 2 | brown | GND | 0V | |
| 3 | red | 5V in | 5V | max 10mA |
| 4 | blue | temp out | 0.5 .. 4.5V | NTC, similar U(T) as CLT |
This version has 4 male pins (out of 5: 1 missing). The first 3 pin is compatible with the MPX4250AP pinout.
Pinout of the 5V, 250 kPa version
| SSC pin | recommended color | signal | range | note |
| 1 | white | MAP output | 0 .. 4.8V | 20..400kPa |
| 2 | brown | GND | 0V | |
| 3 | red | 5V in | 5V | max 10mA |
This version has 3 male pins (out of 5: 2 missing). Note that there is no temperature output in this version.
