In this article we look at a speaker expansion board for your Raspberry Pi Pico. This board has an on board speaker and also a headphone jack. This is a picture of the board The main audio chip on this board after closer examination was…
In this article we look at a Raspberry Pi Pico RTC Module based on the DS1302 chip The Raspberry Pi Pico out of the box does not have RTC capabilities so with the addition of this Here is a picture of the purchased module Lets…
In this article we look at an expansion board for the Raspberry Pi Pico which is designed to test all of the GPIO pins. You can see this pictured below, the board contains 5 push buttons, 1 potentiometer and 20 leds connected to various GPIO…
In this article we look at one of the RP2040 board offerings from Adafruit. In this case its a much smaller sized board called the Adafruit QT Py RP2040 The QT Py RP2040 adds an extra analog pin compared to the Pico which brings the…
In this article we look at another RP2040 board called the SparkFun Pro Micro, this is a low cost basic RP2040 board with minimal features There are two LEDs on the Pro Micro RP2040. The red LED indicates power and the other is an addressable…
The next board that we will look at that has an RP2040 microcontroller is one that I have been looking forward to get, the Nano RP2040 Connect from Arduino. The Nano as well as the impressive RP2040 microcontroller also has native Bluetooth and WiFi connectivity…
If you are looking for a display for a project like a counter, timer or a simple digital clock then the 4-Digit 8-Segment Display Module for Raspberry Pi Pico is a low cost option The SNx4HC595 devices contain an 8-bit, serial-in, parallel-out shift register that…
The Raspberry Pi Pico Relay Board from sbcomponents allows your Raspberry Pi Pico to control up to 4 devices with loads up to 240V AC / 7A or 30V DC / 10A. The 4 channels have an opto-isolator, here is what an opto-isolator does An…
One of the features that is missing from the Raspberry Pi Pico is network functionality. The Pico Wireless Pack from Pimoroni is one solution to the problem. The Pico Wireless Pack attaches to the back of your Pico and uses an ESP32 chip to let…
The Pico-RTC-DS3231 is an RTC expansion module specialized for Raspberry Pi Pico. It incorporates high precision RTC chip DS3231 and uses an I2C bus for communication. More external sensors are allowed to be connected thanks to the stackable design. DS3231 Information The DS3231 is…
