Vocore WiFi IoT board was popular at its launch in 2014 because affordable WiFi boards with I/Os were not common at the time, and it came with an Ethernet dock making it a complete router within a tiny and cute cube. The developers have been working on VoCore2 (aka Vocore V2) with a faster processor, more memory, a lower power consumption, a better WiFi signal, and more I/Os for several months, and have now launched the board on Indiegogo aiming to raise at least $6,000 for mass production.
Vocore2 board specifications:
- SoC – Mediatek MT7628AN MIPS processor @ 580 MHz
- System Memory – 128 MB DDR2
- Storage – 16MB NOR FLASH, 1x SDXC via I/O pins
- WiFi 802.11n 2T2R up to 300 Mbps with either 2 u.FL connector or 1 u.FL connector + on-board chip antenna (Max signal output >19.5dbm peak)
- 2x 10/100M Ethernet interfaces via I/O pins
- I/Os – About 30 GPIOs multiplexed with 3x UARTs, 1x I2C, 1x I2S, 1x reference clock, 1x USB 2.0, 1x PCIe 1.1, 1x high speed SPI (40Mbps max), 1x SPI slave, 2x hardware PWM
- Power Supply – Input: 3.6~6.0V; output: 1.8V, 3.3V.
- Power Consumption – 74mA @ 5V (wifi on, no data transfer); 233mA @ 5V (max speed cpu and wireless)
- Dimensions – 25.4 x 25.4 x 2.8 mm
Considering we have an embarrassment of choices of low cost Linux WiFi boards with easy to use platforms such as Mediatek LinkIt Smart 7688 or Onion Omega2, the main draw to the new Vocore V2 is mostly because of its three docks:
- AirPlay Dock – Adds a micro USB port for power, as well as an audio codec and 3.5mm audio jack to connect to speakers. Dimensions with Vocore2: 25.4 x 25.4 x 9.0 mm
- PoE Dock – To upgrade existing wall-mount Ethernet panel to a wireless hotspot
- Ultimate Dock – Combines audio jack, Ethernet (RJ45) port, micro SD slot, USB 2.0 host port, micro USB port for power and debugging, and a AD/DA converter to connect sensors. It can be used to store data in the SD card, as CCTV DVR system by adding a USB webcam, as a voice command system with a microphone, and so on. Dimensions with Covore2: 28 x 28 x 22 mm
Some extra details about the docks, and some earlier firmware release would have been nice to have, but I could not find this information on their Indiegogo page.
VoCore2 module starts at $12 (Early bird), Vocore2 + Airplay or PoE dock goes for $29, and you’d have to pledge $39 for Vocore2 with Ultimate dock (and case?). Bundle rewards are also available with 5 pieces for each kit. Shipping is not included but only adds $3 to $10 depending on the selected reward, and delivery is scheduled for November 2016 for most rewards, except PoE rewards which should be shipped later in January 2017.
