The pressure Sensor Board for Pico W has NXP's MPXV5010DP sensor which is an integrated on-chip silicon pressure sensor that is signal-conditioned, temperature compensated, and calibrated. Two axial ports are included in the Pressure Sensor Board for Pico to allow industrial-grade tubing. The sensor's maximum error rate between 0 and 85 degrees Celsius is 5.0%. It communicates with the target microcontroller over the SPI interface (CS, SCK, MISO).

The pressure Sensor Board for Pico is made to compare two pressure readings. Taking the difference in gas pressure in a flow tube with different diameters, for instance.

Features:

• 0% Maximum Error over 0° to 85°C
• Ideally Suited for Microprocessor or Microcontroller-Based Systems
• Durable Epoxy Unibody and Thermoplastic (PPS) Surface Mount Package
• Temperature Compensated over -40° to +125°C
• Patented Silicon Shear Stress-Strain Gauge
• Available in Differential and Gauge Configurations
• Available in Surface Mount (SMT) or Through-hole (DIP) Configurations

MPXV5010DP sensor: - Modern monolithic silicon pressure sensors, the MPXV5010DP piezoresistive transducers, are especially well suited for applications requiring a microcontroller or microprocessor with A/D inputs. This transducer uses thin-film metallization, bipolar processing, and advanced micromachining techniques to provide a precise, high-level analog output signal that is proportional to the applied pressure. Industrial-grade tubing can now be accommodated in the axial port.

1.3” Square LCD

The Pressure Sensor Board for Pico comes with an onboard 1.3” Square shaped LCD with a 240 x 240 pixels resolution.

The most unusual aspect of the display is its capacity to read back the display memory across the bi-directional data lines. This fixes a significant problem with most screens, which is the need for a lot of RAM to create effects like transparency or overlapping windows.

Key features are:

• 240 x 240 pixels resolution
• IPS Display Panel
• ST7786 Driver
• SPI Interface

Buzzer

the board also has a fully programmable buzzer which is also multi-tune. It plays up to 5 different tunes and the users can set separate tunes for different actions.

5-way Joystick

The joystick has 5-way operations and is used for moving the data/display to the right, left, up, down, and select.

Additional GPIOs

These additional GPIOs are programmable by the users and can provide great ease of accessing other peripheral devices.
