A RP2040-based dev board with some quirks
SLIM2040 is a custom development board based on the the RP2040 chip.
It comes in a slim form factor and some notable additional features.
Features
- Power supply in the range 4.5~28V
- Convenient and easy integration in industrial environments.
- Can be powered directly by PLCs and other common industrial devices working in the same DC range, including the regular USB.
- Reverse polarity protection
- A Schottky diode to protect from reverse polarity.
- Can be bypassed by shorting the appropriate pad on the back of the board if more current is needed.
- Two user buttons
- Convenient and easy operation.
- Can be used as a controller for sensors or actuators.
- Power LED, User LED and RGB LED
- Convenient and easy way to have a quick glimpse on the status of the system.
- Qwiic/StemmaQT connector
- Convenient and easy way to connect and swap out I2C peripherals such as sensors, etc.
- Designed to pair with an SSD1306 128 × 32 px OLED Display
- Convenient visualisation of data, values or parameters directly on the device.
- Two dedicated GPIO for high voltage operation
- Convenient and easy integration in industrial environments.
- To send and read digital data from PLCs, etc.

Additional GPIO Information
- I2C0 connector on GPIO16, GPIO17
- User button on GPIO20
- User WS2812B Neopixel RGB LED on GPIO21
- ADC0 on GPIO26
- `GPIO23 = Pin(23, Pin.OUT, Pin.PULL_DOWN)`
- `GPIO24 = Pin(24, Pin.IN, Pin.PULL_UP)`
※ In order for the BOOTSEL button to be recognised as a User button, use: `rp2.bootsel_button()`.
※ High-voltage GPIOs make use of N-Channel MOSFETs.
※ OUT pad can switch a maximum of 30V.
※ IN pad control signal can be up to 12V.
※ All the GPIOs except those labeled as high-voltage (HV) operate in the regular 3.3V limit regardless of the input power voltage.
