Pimoroni Automation 2040 W is an industrial/automation controller based on the Raspberry Pi Pico W board that supports I/Os from 6V up to 40V and offers 2.4GHz WiFi 4 connectivity.
The board offers plenty of interfaces including the ADC inputs, four digital inputs, three digital outputs, and three relays whose signals are all available through screw terminals, as well as two Qwiic/STEMMA QT connectors for further expansion.
Automation 2040 W specifications:
- Controller – Raspberry Pi Pico W with Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM, 2MB flash, 802.11b/g/n WiFi 4 module
- 3x 12-bit ADC inputs up to 40V
- 4x digital inputs up to 40V
- 3x digital sourcing outputs at V+ (supply voltage) with
- 4A max continuous current
- 2A max current at 500Hz PWM
- 3x relays (NC and NO terminals) supporting 2A up to 24V, 1A up to 40V
- 3.5mm screw terminals for inputs and outputs above
- 2x Qw/ST connectors for expansion
- 5-pin unpopulated header with 3x GPIO, 3.3V, GND
- Misc – 2x tactile buttons with LED indicators, Reset button, WiFi & Power LEDs
- Power Supply
- 5V via the micro USB port on Raspberry Pi Pico W
- 6V to 40V via 2-pin screw terminal
- Dimensions – TBD; 4x M2.5 mounting holes suitable for DIN Rail mounting with appropriate clips
The board comes fully assembled and is compatible with 12V, 24V and 36V systems. The Automation 2040 W board can be programmed with C/C++ or MicroPython, but the latter may be preferred since Pimoroni has written a Getting Started Guide showing how to connect the board and program it with MicroPython.
The company sells the board for $55.57 on their online store, but if you don’t quite need as many I/Os, there’s also a smaller version – the Automation 2040 W Mini – that goes for $37.05.
