How to Make a $15 Web Server for IoT Applications

Arduino_Leonardo_Ethernet_ENC28J60_Assembled

If you have an embedded project that requires some GPIOs, and Ethernet connectivity, you now have a few choices of low cost low boards such as the Raspberry Pi with Broadcom ARM11 SoC for $35 + shipping, Texas Instruments Connected LaunchPad with an ARM Cortex M4 MCU for $20 including shipping, and today I’ve given a try at a solution to run an HTTP server with an Arduino Leonardo clone connected to ENC28J60 Ethernet module that together cost about $15 including shipping. This Ethernet module has been around for a while and is well supported, I just never took the time to give it a try before. I’ve purchased ENC28J60 module on eBay for $3.46 and connected it via SPI to an Arduino Leonardo clone I acquired as part of a kit via Indiegogo for $12. The kit is not available for purchase outside the crowdfunding campaign, but you can […]

USB2Go ARM Cortex M3 Development Board for Android Smartphones (Crowdfunding)

Many MCU based development boards such as Arduino or mbed platform connect to a computer via USB for power and programming, at least during the development stage. USB2Go, however, is designed with a micro USB port to connect directly to your Android smartphone, although it can also be used for standalone project, and an Arduino compatible baseboard is also available. This board powered by an STM32 ARM Cortex M3 MCU is however mainly destined to interface hardware such as LED, servos, sensors to your smartphone via micro USB providing both power and a communication channel with your Android device. USB2Go hardware specifications: MCU – STMicro STM32 ARM Cortex M3 MCU @ 72 MHz with 128 KB Flash, 64 KB SRAM USB – Micro USB for power and programming Headers – 2x 12 pin headers giving access to GPIO, ADC, PWM, UART, I2C, SPI… Debugging I/F – JTAG 20-pin to SWD […]

MicroView is a Tiny Arduino Compatible Board with an OLED Display (Crowdfunding)

Last year, we’ve been presented with many small Arduino compatible boards such as MicroDuino, RFDuino, BLEDuino, Spark Core, Olimexino-Nano and more… All these boards have been own strength and connectivity options, but if you want to see what going on in your board, you’d either need to connect it to your computer, or connect some LEDs or an external display. Geek Ammo’s MicroView fixes that by providing an Arduino compatible board nicely combined with a built-in OLED display. This allows you to display stats, weather, play games, create wearable projects (watch, necklace), and all sort of other projects that may require a small display. MicroView specifications: MCU – Atmel ATmega328P @ 16 MHz with 32KB flash, 2 KB SRAM, and 1KB EEPROM Display – 64×48 OLED Display Digital I/O – 12 (of which 3 provide PWM output) Analog Input – 6 Operating Voltage: 5V Input Voltage: 3.3VDC to 16VDC, no […]

Arduino based Open Source ECU for Diesel Engines

If you buy a diesel engine without ECU (Engine Control Unit), what would you do? If you’re a hacker like synkooppi, you might just decide to design your own ECU with an Arduino, open source the code, and provide some documentation on your site. Many people already control motors with Arduino boards, they just happen to be electric motor, and not diesel motor. The system works with diesel engines with Bosch VP37 pumps, and it has been used successfully since 2012. The ECU is based on an Arduino Mega board with a 8-bit AVR MCU @ 16MHz. The latest source code is available for download (2013-10-06), and can be uploaded to the board via the Arduino IDE. Configuration is done with text-based interface using serial connection over USB port. Hardware schematics have not been released yet. This open source ECU currently support the following features: Integrated control map editor Diagnostic […]
