SRV-1 WiPort update - successful test of prototype PCB's
We received the prototype batch of circuit boards last week, and installed WiFi on several robots after initial testing.
One of the robots shipped to Lantronix the same day for display next week in their booth at the Embedded Systems Conference in San Jose - you can look for them in booth # 2410.
We kept one of the WLAN prototypes for testing, and everything worked as expected, though we found that we could actually run the module at 921kbps without hardware flow control as long as the JPEG frame sizes remained below 4kbytes (160x128 resolution). After discussing this further with Lantronix engineers and considering some schemes for software flow control, we've decided to modify the circuit board slightly to add a buffer overrun detection signal which will allow us to run the modules full speed at 921kbps, even with larger JPEG frames (up to 640x480 resolution).
We will test the modified circuit shortly, and then update the PCB layout and order a production run of boards. Realistically, we should have first completed modules ready to ship by April 13.
As regards pricing, we will offer the SRV-1 WiPort expansion board for only $15 plus freight to existing SRV-1 owners who supply their own WiPort module and antenna - this includes the voltage regulator, connector, mounting hardware, LED's and passive components - please note that this cost does not include the WiPort and antenna. This offer only applies to existing SRV-1 owners, as it is less than our actual production cost for the expansion board.
The cost of a complete SRV-1 WiPort radio, including expansion board, WiPort and antenna, will be $150 plus freight, and education discounts will apply.
The cost of a complete SRV-1 robot with battery charger and WiPort radio (i.e. SRV-1 robot starter kit with WLAN) in place of Zigbee radios will be $435 plus freight, and likewise, education discounts will apply.
If you are interested in any of these configurations, please contact us via email - support@surveyor.com.
