Andy Brown designed and built an STM32G081 development board: I’ve been an avid user of ST’s F0 series ever since it was launched. The 48MHz Cortex M0 is almost always the perfect MCU for every project that I tend to build and it’s so easy to program and debug that, for me, it’s the default […]

Grbl_ESP32 development board version 3.1
A board to control your CNC machine with Grbl_ESP32 designed by Bart Dring, that is available on GitHub: This is a Grbl_ESP32 CNC Development board. This is a quick and easy way to use and test CNC on the ESP32 controller. Grbl is a great CNC firmware that has been around for nearly a decade. […]
SAMD21 LoRa development board with GPS
Michael Krumpus designed and built a SAMD21 development board with LoRa radio module and GPS receiver, that is available on GitHub: I’ve been doing some LoRa projects lately in order to learn as much as I can about this exciting new radio technology (see this LoRa mesh networking project and this LoRa weather station). ATmega328-based […]
The ARM chip that wont cost an arm and a leg
A small ARM developmentboard from SMDprutser, that is available on GitHub: Searching the prerequisite Chinese websites to satisfy my shopping fetish I came across a neat little ARM Cortex-M0 chip which is an extremely good bang for buck. I believe it is the smallest chip available in a reasonable hand-solderable package (TSOP8). This board gives […]
EasyESP-1: a rapid prototyping and development board for ESP8266
Raj over at Embedded Lab has designed a development board for ESP8266: EasyESP-1 is a rapid prototyping board for the low-cost, WiFi-enabled ESP8266 microcontroller. With an onboard USB-to-Serial converter pre-installed, EasyESP-1 does not require any additional hardware to download your application firmware to the ESP8266 chip. The ESP module used in this development board is […]
First GD32 tests
Sjaak has published a new build, the STM32/GD32F103 QFN32 breakout board: Uptill now I used 0603 sized resistors and capacitors but for this project I switched to 0402 to save a few mm on the board. I have soldered many challenging chip packages so I felt confident. The technique is the same as for bigger […]
Atmel SAM D09 Development board
Dan Watson has designed a development board for the Atmel SAM D09 microcontroller: The Atmel SAM D series of 32-bit microcontrollers includes several devices, each with a long list of features at great prices. Perhaps the best known of the series in the maker community is the SAM D21 due to its use on the […]
CC2538 development board
Jelmer Tiete designed and built a development board for the TI CC2538, that is available at GitHub: It’s a nice little system-on-chip with an ARM Cortex M3, 2.4 GHz 802.15.4 radio and it runs at 32 MHz. Perfect for all your favorite Internet Of Things (IOT) shenanigans. Contiki supports this chip pretty well, which means […]
1mm pitch flex cable passthrough
Kuzyatech has a new project posted, a Flex (FPC) 1mm cable passthrough breakout: By popular demand, the breakout/passthrough combination boards family now includes a 1mm pitch variant This version handles up to 30 signals which seems to be a practical limit of most 1mm FPC connectors. Each signal is numbered and brought to a 0.1mm spacing […]
Basic Experimenter Board for rapid prototyping of electronic circuits
Raj of Embedded Lab has published new project the Basic Experimenter Board for easy prototyping of electronics circuits: Most electronics projects require some common stuff like regulated power supply, input tact switches, and output LEDs during prototyping and testing phase. Wiring these things on a breadboard for every new project could be time consuming and […]
Oops – Again
Sjaak likes to design (and build) PCBs in his spare time. This has a big downside as he has a busy daytime job, which makes him a bit less focussed during the design process. He used a small crystal of which he didn’t had a proper footprint of. No problem as it is a few clicks […]
First steps with the ESP8266-03 development board
As a follow up to the “Development board for the ESP8266-03” post, Limpkin blogged about his first steps with ESP8266-03 dev board: As mentioned in my previous blog post I was very optimistic when designing my ESP8266-03 development board and didn’t even prototype it before launching a batch in production. As I just received a few of these […]
Atmel releases new low power MCUs
Atmel recently announced the release of their next generation of low power 8-bit MCUs. Promising to be pin compatible with previous ATmega family members, these “The Atmel mega168PB, mega88PB and mega48PB are available in 32-pin QFN and QFP packages with additional devices available later this year. All devices are sampling now. Production quantities for the […]
Atsam3u + SDCard + USB cdc/msd + fat32 with at91lib & Chan’s fat code
Limpkin writes: This development platform is primarily aimed at facilitating the realization of high speed (several GHz) functions that quantum physicist need for their experiments, as well as providing data collection capabilities. Without going into many details, it will physically be a 3U rack where users can plug different eurocard modules that perform specific functions. […]
A development board for the ESP8266-03
Limpkin has developed a development board for the ESP8266-03: The ESP8266 modules come with a pre-loaded firmware that will accept some commands through their UART interface (connect to wifi, open udp socket, send data to this IP…). Moreover, since Espressif recently released their SDK you can now load your own custom programs using the existing bootloader. […]
Microcontroller based running light controller
Another project by Rajkumar Sharma over at Electronics Lab, a lights effects board using common bulbs: This project provides some lighting effect by the blinking pattern of the bulbs connected at its output. Up to 8 Bulbs can be connected in between connector CN2 to CN9 and AC power to control them should be connected […]
Hacking Android on the UDOO board (for SATA and S/PDIF)
Computer engineer Primiano Tucci has been experimenting with Android on the UDOO board. I recently came in possession of a UDOO Quad board. The hardware onboard is pretty powerful compared to many other competitor boards. Unfortunately, however, the software support for Android is lagging a bit. In particular, in the latest image shipped by UDOO […]
Review: Kano DIY computer kit
Steve Schuler has posted this review of the Kano DIY computer kit on Science 2.0. I’ve lost count of how many computers I’ve built over the years, but I think it is safe to say that the Kano Computer was the easiest build ever. So simple a child could do it. Kano founders, Yonatan Raz-Fridman, […]

Jan Henrik posted another Instructables, an introduction to the Freedom Freescale KL25Z board: Hello, today I want intoduct you to the Freescale Freedom Board with the KL25Z processor. It is a development board, builded and selled by Freescale. It features a ARM® Cortex™-M0+ , working on 48Mhz. Features: 48Mhz 128KB Flash 16KB SRAM USB OTG An […]
Interfacing the STM32VLDISCOVERY with Semtech’s SX1272RF1BAS module
Milen Pavlov with Netblocks wrote this post on connecting a STM32VLDISCOVERY with Semtech’s SX1272RF1BAS module (LoRa sx1272 transceiver.) This module incorporates the LoRa spread spectrum modem which is advertised as achieving significantly longer range than existing systems based on FSK or OOK modulation. It operates using low power in the ISM bands. Milen’s article includes […]
