A few years ago, I wondered why adding Wi-Fi to Arduino had to be rather expensive ($40+), and why there weren’t any low cost and small form factor Wi-Fi boards for embedded applications. But we’re now in 2015, embedded is “dead” giving rise to IoT, and I’m left wondering how it’s possible to make IoT Wi-Fi modules that cheap, and whether people will ever stop churning out cheap Wi-Fi boards, as I’m flooded with such news weekly… So when I saw yet another ESP8266 board on Kickstarter I was about to dismiss it, but since it was made by Digistump, that has an active community with their other products like DigiSpark Pro or DigiX, I decided to have a closer look. Digistump Oak hardware specifications: MCU – Espressif ESP8266EX 32-bit microprocessor @ 80MHz (overclockable up to 160MHz) with 1MB ROM (~300KB available for user code), 64KB RAM, 512 bytes EEPROM […]

$14 Digispark Pro is a Tiny Arduino Ready Board Supporting over 25 Shields (Crowdfunding)
Digispark Pro is yet another small Arduino compatible board, but it costs only $14, and over 25 small form factor shields for Wi-Fi, BLE, mesh networking, etc.. are available for the platform. Let’s get straight into the hardware specs: MCU – AVR MCU @ 16 Mhz with 16KB Flash Memory (14.5K+ after bootloader) I/Os 14 I/O pins (2 shared with USB) I2C, true SPI, UART, LIN, and USI ADC on 10 pins 3 PWM Channels (which can be assigned to a selection of pins) USB – Micro USB for debugging, communication and power Misc – One button usable as reset, program, or user button, Power and Test/Status LEDs, user accessible solder jumpers to disable LEDs, and other features for lower power consumption Power – 5V via micro USB, or External Source – 5v or 6-16v (automatic selection). On-board 500ma 5V regulator Dimensions – 26.7mm x 18.3mm The board is compatible […]
$59 Digitstump DigiX is an Arduino Due Compatible Board with Wi-Fi and Mesh Networking
The DigiX, by Digistump, is hobbyist board with an Atmel SAM3 Cortex M3 MCU @ 84 MHz, embedded low power Wi-Fi (b/g/n) and mesh networking,audio output, USB on the go support, and the company claims it is 100% compatible with anything that works with the Arduino Due, with some extra I/Os for a total of 99 I/O pins. The hardware specifications go as follows: MCU – Atmel AT91SAM3X8E 32-bit ARM Cortex M3 Processor @ 84 Mhz with 96KB SRAM, 512KB Flash Connectivity On-board 802.11b/g/n WiFi Module (FCC/CE Approved) On-board nRF24L01+ wireless module (removable) – 2.4Ghz band 99 I/O Pins including 12 PWM, 12 Analog Input, 2 Analog Output (DAC), CAN bus, 4x UARTs, 2x I2C, SPI, JTAG, DMA and more.
