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 […]
BIGTREETECH CB1 – A Raspberry Pi CM4 compatible Allwinner H616 system-on-module
The BIGTREETECH CB1 core board is an Allwinner H616 quad-core Arm Cortex-A53 system-on-module (SoM) that follows the Raspberry Pi CM4 form factor and was designed by BIGTREETECH, a company whose main business is related to 3D printer motherboards and their peripherals. The BIGTREETECH CB1 comes with 1GB RAM, an HDMI output interface, 2.4GHz WiFi, and 100Mbps Ethernet. The CB1 has better multimedia capability than the CM4 with support for 4Kp60 H.265/H.264 video decoding and 1080p60 H.264 video encoding, while the Broadcom BCM2711 processor on the CM4 can only handle 4Kp60 H.265 and 1080p60 H.264 video decoding, and 1080p30 H.264 video encoding. Some disadvantages include the lack of CSI and DSI interfaces on the Allwinner H616 system-on-module and the presence of only one video output interface against two for the Raspberry Pi CM4 module. BIGTREETECH CB1 specifications: SoC – Allwinner H616 quad-core Cortex-A53 @ 1.5GHz with Mali-G31 MP2 GPU with OpenGL 3.2, […]

UP 4000 x86 SBC review with Ubuntu 22.04
The UP 4000 is a credit-card / Raspberry Pi-sized single board computer based on an Intel Apollo Lake processor. AAEON sent me the model with an Intel Atom x7-E3950 quad-core processor, 4GB RAM, and a 64GB eMMC flash, and in the first part of the review, I installed Ubuntu 22.04 since the board would initially only boot to the UEFI shell out of the box. I’ve now spent more time with the board, and in this article, I will report my experience with the UP 4000 SBC running Ubuntu 22.04 checking out features, performance, video playback, power consumption, and so on. Ubuntu 22.04 System info Let’s check out some information after I’ve upgraded the system to the latest packages:

SBC Case Builder 2.0 released with GUI
SBC Case Builder 2.0 tool to create enclosures for single board computers has been released with a customizer graphical user interface, additional cases & SBCs, support for variable height standoffs, and more. We wrote about the SBC Case Builder tool to easily generate various types of 3D printable enclosures using OpenSCAD earlier this year. The SBC Model Framework used in the solution was focused on ODROID boards, and you had to type the parameters in a configuration file. SBC Case Builder 2.0 software changes that with a convenient-to-use graphical interface allowing for the dynamic adjustment of any of the case attributes. The new version of the software also supports variable height standoffs, multi-associative parametric accessory positioning, and offers 8 “base cases”, namely shell, panel, stacked, tray, round, hex, snap, and fitted. The solution works with 47 SBCs defined in the latest version of the SBC Model Framework. The following SBCs […]
Maker Pi Pico Mini adds battery, buzzer, GPIO LEDs to Raspberry Pi Pico (W)
Cytron’s Maker Pi Pico Mini is an add-on board for the Raspberry Pi Pico and the latest Raspberry Pi Pico W with a battery port, GPIO status LEDs, a WS2812B Neopixel RGB LED, passive piezo buzzer, user and reset button, as well as “Maker” ports for expansion. It comes with most of the features found in the company’s Maker Pi Pico board, but in a much more compact form factor, since the add-on board is only slightly larger than the Raspberry Pi Pico to allow for soldering using the castellated holes. Maker Pi Pico Mini specifications: Fitted with Raspberry Pi Pico / Pico W LEDs – 6x Status indicator LEDs for GPIOs, 1x RGB LED (WS2812B Neopixel) Audio – 1x Passive piezo buzzer (to play musical tones or melody) Buttons – Reset and user buttons Expansion 3x Maker ports compatible with Qwiic and STEMMA QT, as well as Grove modules […]
Raspberry Pi RP2040 gets into BBC Micro:bit lookalike board
ELECFREAKS Pico:ed V2 is a Raspberry Pi RP2040 board heavily inspired by the BBC Micro:bit with an edge connector exposing rings suitable for crocodile clips, a 17×7 LED matrix display, and designed for the classroom. We’ve seen several BBC Micro:bit clones – or rather adaptations – over the years with boards such as the SiFive Learn Inventor, Elecrow Mbits, and HiHope “Big Brother” board. The Pico:ed V2 adds to the list, and the main differences are that it is based on the Raspberry Pi RP2040 microcontroller instead, and does not come with wireless connectivity relying on a USB interface only. ELECFREAKS Pico:ed V2 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB of SRAM Storage – 2MB QSPI flash Display – 17×7 dot-matrix display USB – 1x micro USB 1.1 port for power, data, and programming I/Os 25-pin notched “Wavy” connector with up to […]
