DJ, is there a way to convert the EZ-B to use USB or RS232 to communicate with the host PC? I'm considering using a mini or nano-itx mobo to embed a PC into the robot and using BT in such a scenario is rather superfluous. Was hoping I could pull off the BT module and stick on a USB module/adapter. Thanks...
Do you have 2.1 or 3?
Or maybe this super tiny Pololu USB-to-Serial Adapter...
Actually if you're looking at other serial communication alternatives I have already successfully tested the EZ-B with a Long range RF networking modules made by Synapse Wireless that just connected to the TX and RX lines of the EZ-B and I powered it with the 3.3V regulator on board the EZ-B as well. This extended the range of communication to over 200 ft. from indoors at my PC to the EZ-B outdoors.
Here's links for compatible serial communication items that are sold at HVWtech/Solarbotics:
TTLy FTDI
Xbee Module
Synapse Module
Sparkfun FTDI Basic Breakout
Synapse RF100PC6 Module Features:
- Can be programmed as a stand alone unit (8-bit microcontroller built in)
- 8 A/D pins (2 more than Xbees)
- 19 I/O pins (11 more than Xbees)
- Don't have to configure modules with AT commands or drop downs, modules are configured with snappy scripts (python) that are quickly loaded into the modules. There are many example scripts included with the program.
- Instant-on, self-healing, multi-hopping wireless mesh networking (Series 1 Xbees don't have these features)
Real world Synapse test: Communication range of over 225 ft. from indoors through many walls & a metal outer structure to an outdoor location.
Real world Xbee Series 1 test: Communication range of around 40 ft. with 1 obstructing wall.
Although the Xbee series 2 and 2.5 do have upgraded specs, they still don't seem to be able to catch up to the Synapse Modules in terms of capability. Truth be told though, the Xbees are still the cheaper system.
