Analog Sensor Connector
The pinout of the analog sensor interface on the PiShield are as follows:
| PWR |
| SIG |
| GND |
Digital (I2C) Sensor Connector
The pinout of the digital sensor interface, looking into the female connector of the shield are as follows:
| NNN | PWR |
| SDA | SCL |
| NNN | GND |
(NNN = no connection)
PiShield Schematic
Other Technical Info
- A2D Chip: MCP3008 via SPI interface running at 5V on CE0. (Possible to use an additional SPI device on CE1)
- All digital and analog sensor ports have 5V VCC
- 5V I2C lines have 10k pullup resistors
- Two GPIO headers on GPIO21 and 22 (Wiring Pi pins 2 and 3) have a direct connection to GPIO pins (3.3V logic)
