Adapters convert Raspberry Pi Zero 2 W into Raspberry Pi 3 or 4

Spotpear’s Raspberry Pi Zero 2 W to Raspberry Pi 3/4 adapters would not exist in a “normal” world of abundance that still existed a little less than 3 years ago. But I suppose extraordinary times require extraordinary adapters… If you have a spare Raspberry Pi Zero 2 W lying around but would rather like getting the ports from a Raspberry Pi 3 or Raspberry Pi 4, Spotpear has designed three adapters that can also be used as USB docks from a computer or mobile phone. The first adapter the “ZERO to 4B” will get you a Raspberry Pi 4-looking SBC with a Raspberry Pi RP3A0 system-in-package (Quad-core Cortex-A53 CPU + 512 MB RAM), and most of the same ports, except only three USB 2.0 Type-A ports are available with a maximum speed of 480 Mbps, and only one HDMI output due the inherent limitations of the Raspberry Pi Zero 2 […]

Miniature Raspberry Pi CM4 carrier board only exposes USB-C port and 40-pin GPIO header

Mirek Folejewski’s (aka Mirko Electronics) PicoBerry is an open-source hardware, miniature Raspberry Pi CM4 carrier board with just a USB Type-C port for power, a 40-pin Raspberry Pi GPIO header, and barely anything else. At just 70x20mm, the 2-layer board only adds a few LEDs, namely the ACT/PWR LEDS and two user LEDs, and supports any Raspberry Pi CM4 module with eMMC flash, but not the Raspberry Pi CM4 Lite since the board does not include a microSD card slot. PicoBerry specifications: Supported system-on-modules – Raspberry Pi CM4 with eMMC flash, and possibly compatible SoMs such as Radxa CM5 or Pine64 SoQuartz64 USB – USB Type-C for power Expansion – 40-pin GPIO header with the same layout as on Raspberry Pi 4 or other Pi boards with a 40-pin header Misc – ACT/PWR LEDs, 2x user LEDs (green.red) Power Supply – 5V DC/3A via USB-C port, Dimensions – 70x20mm (2-layer […]

Making a weather station with Maker Pi Pico Mini board and SparkFun SerLCD display

Cytron’s Maker Pi Pico Mini comes with a Raspberry Pi Pico or Raspberry Pi Pico W microcontroller board. It has the same features as the larger Maker Pi Pico including a GPIO LED, WS2812B Neopixel RGB LED, a passive piezo buzzer, programmable push buttons, and a reset button. I would like to thank Cytron for sending the Maker Pi Pico Mini board fitted with a Raspberry Pi Pico W as well as a character RGB LCD and a 3.7V Lithium Polymer battery. In this tutorial, we will show how to make an Internet connected weather station with the Maker Pi Pico Mini board using Arduino code and the OpenWeather API. We’ve already covered the Maker Pi Pico Mini board, so we’ll have a closer look at the accessories SparkFun SerLCD character display The SparkFun SerLCD is a 16×2 character display with a Microchip ATmega328P microcontroller that handles commands sent from […]
