Cytron CM4 Maker Board review – Part 2: NVMe SSD, RTC, Buzzer, Grove modules, ChatGPT…

Cytron CM4 Maker board Review

We’ve already checked out Cytron’s CM4 Maker Board kit with a Raspberry Pi CM4 system-on-module and booted the system with the included 32GB “MAKERDISK” Class 10 microSD card preloaded Raspberry Pi OS in the first part of the review. For the second part of the CM4 Maker review, I’ve mostly used the 128GB NVMe SSD provided by the company and played with other features of the board including the RTC, the buzzer, some Seeed Studio grove modules, and even got help from ChatGPT for one of the Python programs I used. Booting Cytron CM4 Maker Board with the “MAKERDISK” NVMe SSD I connected several Grove modules with GPIO and I2C interfaces, a Raspberry Pi Camera Module 3, an Ethernet cable, two RF dongles for a wireless keyboard and mouse, an HDMI cable to a monitor, and finally inserted the provided 5V/3.5A USB-C power adapter. The MAKERDISK SSD comes with Raspberry […]

Giveaway Week 2022 winners announced!

CNX Software Giveaway Week 2022 Winners

CNX Software’s Giveaway Week 2022 has just ended, and it’s time to announce the winners. Just like last year, some companies added to the review samples I offered with Rakwireless and ELECFREAKS offering a LoRaWAN devkit and an educational robot respectively. If you check out the photo of the items given away below you’ll find quite more than seven because the SONOFF NSPanel kit includes four Zigbee modules, and more importantly, we also organized a parallel giveaway week on CNX Software Thailand with small boards such as the Raspberry Pi Zero W or XIAO BLE. We had eight winners on CNX Software: NanoPi R5S gateway – Ingmar, GERMANY e-con Systems e-CAM20_CURB camera – Johnny, ESTONIA Pico:ed Smart Cutebot Kit –  jednorozec, CZECH REPUBLIC Pico:ed V2 board – Leonardo, BRAZIL Sonoff NSPanel Pro and Zigbee modules – Tim, CANADA RAK Developer Kit (Air Quality Kit) – Magnus, SWEDEN GL.iNet GL-S10 BLE […]

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

Maker Pi Pico Mini Weather Station

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 […]

Maker Pi Pico Mini adds battery, buzzer, GPIO LEDs to Raspberry Pi Pico (W)

Maker Pi Pico Mini

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 […]

Getting started with Maker Nano RP2040 using CircuitPython: Blinky, RGB LED, and Piezo Buzzer

Maker Nano RP2040 circuitpython guide

CNXSoft: This getting started guide was initially posted in Thai language by Suthinee Kerdkaew, and I’ve just translated her work into English with some minor edits. As discussed in an earlier article, Maker Nano RP2040 is a board following the Arduino Nano form factor, but with a more powerful Raspberry Pi RP2040 microcontroller. The board also comes with plenty of LEDs, as well as two RGB LEDs, and a piezo buzzer for audio output. Mr. Jean-Luc Aufranc has just given me a Maker Nano RP2040 board received from Cytron for review. I’ve never used a board before, so it’s my first experience, and in this article, I’ll try to program Maker Nano RP2040 with CircuitPython with three demos: a blinky sample, changing the color of the RGB LEDs, and playing a melody through the piezo buzzer. Let’s see if I can do it. Let’s get started. I first downloaded the […]

Maker Nano RP2040 offers Arduino Nano, Grove and Qwiic modules compatibility

Maker Nano RP2040 vs Raspberry Pi Pico

Cytron Maker Nano RP2040 is board similar to Raspberry Pi Pico but with Arduino Nano form factor, a proper reset button, two RGB LEDs, single color LEDs for some GPIOs, a buzzer, as well as two Qwicc/STEMMA QT connectors that can also be used to connect Seeed Studio Grove modules using provided conversion cables. While the board mostly aims to be an Arduino Nano/Maker Nano upgrade, there are some notable differences with the I/O voltage being limited to 3.3V without 5V tolerance, and there are only four ADC inputs (A0 – A3) instead of eight on the Arduino Nano. Maker Nano RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 125 MHz with 264KB internal RAM Storage – 2MB flash Audio – Piezo buzzer with mute switch Expansion 2x 15-pin headers with 22x GPIOs, 14x of which with LEDs,2x I2C, 2x UART, 2x SPI, 14x PWM, 4x […]
