There have been so many low cost Wi-Fi modules and boards with GPIO headers announced this year, especially on crowdfunding sites, and from the hardware point of view, Zero+ (Zero Plus) board looks very much like many other Ralink RT5350 boards such as Vocore or AsiaRF AWM002, but what makes it different is that it can be programmed with Lisp from a web-based IDE.
But let’s go through Zero+ board specifications first:
- SoC – Ralink/Mediatek RT5350 MIPS processor @ 360MHz with dual band 802.11n Wi-Fi with data Rate up to 150Mbps
- System Memory – 32 MB RAM
- Storage – 8MB to 16 MB SPI Flash (for firmware)
- Expansions Headers – 2x headers with access to I2C, SPI, USB, 2x UART, JTAG, and 14x GPIOs
- USB – 1x USB host port, 1x micro USB for power
- Misc – 2x buttons
- Dimensions – 36 x 25mm (possibly module dimensions only, not full board).
I’m quite confident the hardware should be OK, as they are using an existing Wi-Fi module (WL-AM01-5350-V1.2) soldered to a baseboard with USB ports, buttons, and expansion headers.
The board is also a standard router running OpenWRT, so you should also be able to access it, and configure it in a more usual way if you prefer.
SmartMatrix, the company behind the project, is also providing ChipDuino, a tiny Arduino board supporting DIP MCU, to add more I/Os to Zero+, and support for a variety of sensors such as a VGA webcam, temperature and humidity sensors, light sensors, LEDs, gyroscopes, TFT and OLED screens, a PM 2.5 air quality detector, an infrared module and a microphone.
In order to mass manufacture the board, the company has launched a flexible funding Indiegogo campaign planning to raise $25,000 or more. An early bird pledge of $19 can get you a Zero+ board, and after the first 100 boards, pledge will be $25. Many of the perks are kits going from $39 to $69 with sensors, a camera, an LCD display, etc… Albeit, no explicitly written, international shipping is probably included in all perks, and delivery is scheduled for February 2015.
