Logging / NMEA0183 Wi-Fi Adapter

In addition to developing our apps for Android, iPhone and iPad devices, we are also developing low cost NMEA to Wi-Fi interfaces.

The NMEA0183 to Wi-Fi adapter has had good feedback from testers out in the field. We now have the final run of pre-production boards in, and these tested OK. Now we are finishing off the code with a better user interface for the configuration screens; simultaneous UDP and TCP connections; and increasing the number of simultaneous TCP connections.

We have the device live on Kickstarter now, and a limited number are available at just £50 (approx. €57 or US$65) each, for delivery in September. We also have a new web site up for this device at www.nmeatools.com, and we will shortly be adding the existing USB data logger and some other tools to it.


1 bi-directional, fully opto-isolated NMEA0183 port with reverse polarity and over-voltage protection. User selectable speeds from 4800bps to 38400bps
 Configuration Either as an Access Point (AP) or as a client to another AP such as a router.
 Protocols 802.11b/g/n
 Channels All Wi-Fi channels available. Channel is selectable by user.
 Security WEP2
 Protocols TCP, UDP Broadcast, UDP Multicast
 IP addresses and port 
All user configurable. When a client, IP address may be fixed or dynamic. When an AP, can act as a DHCP server
 Keep alive
Optional keep-alive sentence over TCP to avoid the connection being dropped through timeouts, and user configurable time-out on the port to avoid it getting locked by a dropped connection
 Wi-Fi Antenna
 LEDs and Switches
Press button switch for reboot and factory reset. LEDs for power, NMEA In, NMEA Out, Wi-Fi and Reboot.
12/24V DC, 65mA @ 12V
 Configuration Password protected configuration via web pages, or through NMEA0183 sentences over Wi-Fi.
