Hardware

The SimpleHAT is a Raspberry Pi Zero W HAT with multiple functionalities. It can operate as a standalone unit or as a part of more complex system, for example Solar Powered IoT camera. The SimpleHAT hardware includes:

• Circutry for powering ON/OFF Raspberry Pi using external signal
• Placeholder for Raspberry Pi Camera module
• Placeholder for 0.91" OLED display module
• Placeholder for 1.3" OLED display module
• Placeholder for UART to USB converter
• Placeholder for I2C (QWIIC)

Note: Due to physical limitation, not all hardware options can be used togrther

RPI Software

• ON/OFF

For ON/OFF functionality use Pimoroni one-line installer for daemon configuration:

curl https://get.pimoroni.com/onoffshim | bash

IMPORTANT Do not use pushbutton while using external signal for ON/OF as it might result in damaging of external driving circuitry. There is no protecting circuit to prevent it. Use only one ON/OFF source at a time.

• I2C OLEDs There are multiple online tutorials and example code available online

• Raspberry Pi Camera UV4L There are multiple online tutorials and example code available online. We use UV4L - for installation details see UV4L
