It’s very easy to connect
- LDR light sensors
- FSR pressure sensors
- Flex sensors
- Sharp GP2Y0A* infrared distance sensors
- Servo motors
and use them in a patch.
Note that the GPIO’s are 3.3V (VDD) is the digital 3.3V supply, VDDA the analog reference (also 3.3V). Applying 5V to the GPIO’s is outside specification and may cause damage to the board.
