# Fossdeck
|
|
## Warning: This project is still relatively young. Software will be buggy and hardware may be flawed.
|
|
### An open-source modular system for science and fun based on the RP2040 platform and micropython.
|
|
|
|
## The hardware
|
|
The hardware consists of a handful of simple components:
|
|
1. Raspberry Pi Pico (or compatible microcontroller)
|
|
2. SSD1306 oled display (128x32)
|
|
3. Some perfboard and momentary switches to create a control board
|
|
4. A diy power junction to connect various things to
|
|
5. 1100+ mah lipo battery
|
|
6. lipo charge controller
|
|
7. Wire (duh)
|
|
8. A toggle switch to control power from the charge controller to the device
|
|
|
|
(Pictures and schematic coming soon)
|
|
|
|
## Flashing the software
|
|
To install the operating system to your fossdeck:
|
|
1. Install Thonny
|
|
2. Open the main.py file in thonny
|
|
3. Plug in your fossdeck
|
|
4. In the bottom right of thonny, click "default"
|
|
5. Select micropython
|
|
6. Select install
|
|
7. Once completed, press the play icon in thonny
|
|
8. Select pi pico on the popup
|
|
9. Thonny will flash the OS to your fossdeck
|
|
10. Check your fossdeck's screen. If nothing shows up, check all of your hardware connections and ensure you connected everything to the correct pins.

## Creating modules
|
|
The fossdeck is designed with 2 easily accessible expansion ports for various sorts of modules.
