The Raspberry Pi PICO Shield is an adapter that allows you to install Raspberry Pi PICO compatible modules in the mikroBUS™ slot or connect mikroBUS modules (such as MikroElekronika's Click®) to Raspberry Pi PICO modules.

Almost all signals not used by mikroBUS from the installed Raspberry Pi PICO are output to the AUX1 and AUX2 connectors, which makes it possible to use almost all Raspberry Pi PICO functions without changing the programs.

The I2C interface is most often used in the design of devices and instruments based on this module. For this, the module has I2C connector through which you can connect external devices and sensors.

The Raspberry Pi PICO Shield contains the voltage regulator AMS1117-3.3. On the bottom-side there is a jumper defining the 3V3 source on the mikroBUS (from the installed to Raspberry Pi PICO module or from AMS1117-3.3). By default - from the installed module.

Optionally, a BME280 is installed on the bottom-side of the module (7-bit address on I2C = 111011x). The address for BME280 is selected with jumpers on the bottom-side. The default address should be 1110111.

The Raspberry Pi PICO Shield size 51 x 29.21 mm.

The main areas of application of the module:

• Data acquisition systems (DAS)
• Scientific and medical devices
• Smart home and building automation
• HVAC and air monitoring
• Consumer electronic
• Toys

With Raspberry Pi PICO Shield, it is easy to use Raspberry Pi PICO modules to control the following Pro Series I/O modules:

• I2C 4AI ADS1x15 Pro
• I2C 2RO+2AI Pro
• I2C 2RO+2DI Pro

You can also learn more about the I2C 2RO + 2DI Pro module on the IoThings Digital page at Crowd Supply.
