VoCore Wi-Fi module selling for $15 to $20, and it’s corresponding VoCore Dock with Ethernet has been quite popular, and at the time of writing, the project has already received $40,000 in funding with 50 more days to go. But if you’d rather get something for the same price, a few months early, and an already FCC/CE certified and proven module and tiny IoT server, AsiaRF has also launched a crowdfunding campaign for their AWM002 Wi-Fi module running OpenWRT on the same Ralink RT5350 found on the VoCore. as well as AWM002 Tiny Kit which adds Ethernet and USB, and a larger board with easier access to all ports and I/Os.
As a reminder, let’s go through AWM002 specifications again:
- SoC – Mediatek/Ralink RT5350 MIPS 74KEc core @ 360 MHz dual band 802.11n Wi-Fi with data Rate up to 150Mbps, hardware NAT, QoS, TCP/UDP/IP checksum offloading.
- System Memory – 32 MB
- Storage – 8MB NAND flash (for firmware)
- Security – 64/128-bits WEP, TKIP,WPA, WPA2,AES,WPS
- Multi-modes – AP/Client
- Antenna – 1x iPex connector (PIFA optional)
- Transmit Power (EIRP)
- 11n HT40 MCS7 : +14 dBm
- 11b CCK: +20 dBm
- 11g OFDM: +16 dBm
- Receiver Sensitivity
- -70dBm at HT40 MCS7
- -78dBm at 54Mpbs
- -90dBm at 11Mpbs
- PIN I – 24-pin with access to GPIOS, 3.3V, 1.2V, GND, UART, USB, Ethernet..
- PIN II – 16-pin with access to I2C, I2S, PCM, Ethernet…
- Power – +3.3V
- Dimensions – 25x35mm
- Certifications – FCC/CE
The module is already supported by OpenWRT, and provides access to various I/Os such as GPIOs, I2C, UART and so on. You could develop monitoring, communication or surveillance application, such as adding Wi-Fi to a USB printer, connecting a ZWave USB module to gather data from sensors, Wi-Fi IP Cameras, Wi-Fi speakers, adding Wi-Fi to Arduino, cloud storage servers, and so on.
AsiaRF is looking for $6,000 in funding (flexible funding Indiegogo campaign), and you can pledge as low as $15 (Early bird) for AWM002 module, after which it will be $23. The large base board without module goes for $35, and AWM002 tiny kit (pictures at the top of the post) can be had for $38. There are also perks to pledge for larger quantities, and even have your own RT5350 board being designed. Shipping is included to the US, Canada, Switzerland, China, Singapore, Malaysia, Thailand, South Korea, India, and the Netherlands, and it’s $5 to the rest of the world. The campaign will complete by the end of June, and shipping is scheduled for July.
