DiP-Pi WiFi Master for Raspberry Pi Pico

The DiP-Pi WiFi Master is an advanced WiFi connectivity add-on board for the Raspberry Pi Pico offering ESP8266 WiFi connectivity, MicroSD card slot, sensor interfaces, a reset button and more!

It’s a superb option for a Raspberry Pi Pico IoT project with the onboard storage and sensor interfaces providing an excellent foundation for datalogger, plant monitoring and other similar project types! DiP-Pi WiFi Master – Dual In-line Package WiFi for your Pico!

There are currently two other versions of the DiP-Pi available in the range – the DiP-Pi PIoT and the DiP-Pi Power Master. The quick comparison table below explains the headline feature differences:

Key Feature	PIoT	Power Master	WiFi Master
6-18V Power Input (EPR)	Yes	Yes	–
Battery Power/Charging	Yes	Yes	–
Onboard ESP8266 WiFi	Yes	–	Yes
MicroSD Slot	Yes	–	Yes
1-wire Interface	Yes	Yes	Yes
DHT22/21 Interface	Yes	Yes	Yes
Humidity/Temp Sensor Interface	Yes	Yes	Yes

Note: Raspberry Pi Pico not included. You’ll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.

Feature Summary

• ON/OFF power switch (Pico USB)
• ESP8266 WiFi networking
• Micro SD card slot
• 1-wire interface (pads)
• DHT-11/22 Humidity/temperature interface (pads)
• Reset button
• Multiple onboard indication LEDs
• Fully assembled – no soldering required (unless you want to add interfaces)
• Plenty of ready-to-use MicroPython and C/++ examples

Onboard WiFi (ESP8266)

The DiP-Pi WiFi Master is also equipped with a WiFi ESP8266 module with an embedded antenna. This feature opens a wide range of IoT applications for your projects and applications. Provided examples include a simple web server setup. Interaction with WiFi is performed via AT commands.

MicroSD Card Socket

A microSD card slot is provided for storing your application’s data or even for executable software for your Pico! The SD is managed via the Raspberry Pi recommended SPI interface.

1-Wire and Sensor Interfaces

In addition to all of the above features, the DiP-Pi WiFi Master is also equipped with an embedded 1-wire interface (pads), DHT11/22 sensor interface (pads). The 1-wire interface includes ESD protection and 4K7 resistor, and the DHT interface includes a 10k resistor.

The combination of WiFi connectivity and sensor interfaces make the DiP-Pi WiFi Master ideal for IoT applications such as data loggers, plant monitoring and many similar projects!

Reset Button

The DiP-Pi WiFi Master includes an embedded reset button for the Pico, alongside an on/off power slide switch.

MicroPython and C/C++ Examples

DiP-Pi WiFi Master is supported with plenty of ready to use examples written in Micro Python or C/C++.
