“BluePill” is a $2 Arduino Compatible Development Board Based on STMicro STM32 MCU

I’m amazed that if your budget for a board was just $5 for one MCU board, you now have so many options for your electronics projects: ESP8266 boards, a few STM8 boards, One Dollar Board project, and many more… Other options are “BluePill” or “RedPill” boards based on STM32 or GD32 32-bit ARM Cortex M3 micro-controllers that go for about $2 shipped, and can be programmed with the Arduino IDE thanks to STM32Duino project. BluePill board specifications: MCU – STMicro STM32F103C8T6 ARM Cortex-M3 MCU @ 72 MHz with 64KB flash memory, 20KB SRAM. USB – 1x micro USB port for power and programming Debugging – 4x pin SWD header or micro USB port Expansion – 2x 20-pin with power signals, I2C, SPI, GPIOs, ADC inputs, etc… Misc – Reset button, two jumpers (for boot mode), power and user LEDs. Power – 5V via USB, 2.0-3.6V power via 3.3V pin on […]

Arduino Industrial 101 Board Powered by Atmel AVR and Atheros AR9331 WiSoC Targets Industrial IoT Applications

Arduino boards were first used by hobbyists, educators and their students, but in recent year more and more professional engineers have started to build prototypes with Arduino boards before moving to the design of the final product. Arduino Srl went further by designing an industrial grade board, namely Arduino Industrial 101, combining an Atmel AVR for real-time I/O control, and a Qualcomm Atheros AR9331 for WiFi connectivity. Arduino Industrial 101 (A000126) specifications: Arduino part MCU – Atmel ATmega32u4 AVR MCU @ 16 MHz with 32KB flash, 2.5 KB SRAM, 1KB EEPROM Digital I/O Pin – 20, with 7 PWM and UART Analog Input Pins – 12 DC Current per I/0 – 40 mA Operating Voltage – 5V Linux (LininoOS) part (101 Industrial LGA “Chiwawa” module) Processor – Atheros AR9331 MIPS processor @ 400 MHz System Memory – 64 MB DDR2 Storege – 16 MB flash WiFi – 802.11 b/g/n […]

The “One Dollar Board” Project Aims to Teach Electronics in Developing Countries (Crowdfunding)

I’ve already tried a one dollar board based on STM8s in the past, but it required a separate STLink debugger, installing a toolchain, and a few other steps. The “One Dollar Board” project, born in Brazil, has different objectives, as it aims to provide an easy way for pupils around the world to getting started with electronics, by simply connecting it to the USB port of a computer or board capable of running the Arduino IDE, and following the instructions printed on the board. One Dollar Board specifications: MCU – 8-bit MCU (likely Atmel AVR) with 8 KB flash 6x GPIO (input and output ports) USB – 1x USB port for power and programming Misc – 2x LEDs, reset button Expansion – Spaces for Wifi ESP8266, Atmel 24C256 serial EEPROM (256 KB), and L293 Driver motor (unclear where though) Power Supply – 5V via USB Dimensions – Compatible with Arduino […]

Arduino Yún Shield Adds Ethernet and WiFi to Arduino Boards for $50

You can now add WiFi to Arduino for about $3 thanks to ESP8266, and it’s been long possible to add Ethernet with ENC28J60 module now selling for the same $3. Alternatively, if you want some a little more powerful, you could also use IoT modules running OpenWrt such as a $30 WrtNode or $13 LinkIt Smart 7688 both capable of supporting Ethernet with some hacks. But if you’ve been used to Arduino Yun, have a few spare Arduino boards, or simply think the other solutions are just too cheap, Arduino LLC has just launched Arduino/Genuino Yún Shield for $49.90 / 43.90 Euros. Arduino Yún Shield specifications: SoC – Qualcomm Atheros AR9331 MIPS WiSoC @ 400 MHz System Memory – 64 MB DDR2 Storage – 16 MB flash Connectivity – 10/100 M and 802.11 b/g/n WiFi USB – 1x USB 2.0 host port Board interfacing – SPI and HW Serial Misc […]

AAduino Arduino Compatible Board Fits Neatly into an AA Battery Holder

Johan Kanflo has been using Arduino compatible boards based on Tiny328 MCU with an ISM radio module (wireless Arduino clone), but he found that finding a case was not easy, and was quite not ready to to design its own and print it with a 3D printer. So instead he shrank the board to fit into an AA battery case bought on Ebay with two AA batteries taking the remaining slots. That’s the result. AAduino board specifications: MCU – Atmel ATMega328p clocked at 8 MHz to save power Radio – RFM69C ISM transceiver module Sensors – Two DS18B20 temperature sensors Misc – Indicator LED Keystone battery terminals rotated 180° to act as positive and negative terminals. Power – 2x AA batteries The project is also open source hardware, with all hardware files released under the MIT license on Github, where you’ll also find a demo sketch for the board. Via […]
