Grass Patch board resources

This repo contains a schematic for the module, as well as datasheets for all of the important components!

What are you getting?

• A USB Nugget, with its:
• WiFi and Bluetooth capabilities
• 128x64 SH1106 OLED display
• 4 clicky buttons
• A Neopixel LED

It's mounted onto a patch of grass, on which you'll find:

• a (pretty loud) buzzer with MIDI playback support
• an LED bargraph driven from an I2C IO expander
• a LoRa modem from SeeedStudio, based on the SX1262 chip with wide software support
• an infrared transmitter-receiver pair that can make two boards talk together
• a temperature sensor hidden inside of a ball of yarn
• an extra sensor port for I2C sensors of your choice!

How to get at it?

• Install Thonny on your computer

• If we haven't done this already - download and flash MicroPython onto your Nugget

• Upload hw.py and sh1106.py - they're hardware support libraries

• Upload main.py and see it play a melody

• Hack away at main.py to play with the onboard devices and sensors!

  Notes:

• Some components, like the compass and the LoRa modem, will require libraries. For the compass, you can try out this library, and for the LoRa modem, feel free to refer to one of the SX1262 libraries!

• Peruse the files in the datasheets/ folder to learn more about the components
