I would like to know if the comm bords of both IoTiny and the new v4/2 are the same? If yes, why does the v4 upgrade cost more than the IoTiny Thanks.
Looks to me that the 4/2 board has more going on with it. Bigger, more digital, i2c, adc ports and comm ports.
/2 comm upgrade is $29.99 and the IOTiny is $24.99. /2 has more pins than the tiny. Protocol for comm, I believe are the same on both boards.
Important to read the product descriptions
IoTiny is a self contained tiny EZ-B that has 8 digital pins, camera port, external speaker port, 1 i2c and 2 adc ports
Comm 2 upgrade is ONLY an upgrade to existing EZ-B v4 users
EZ-B v4.x/2 is a complete self contained EZ-B with 24 digital ports, 8 adc, 3 i2c, camera, and built in speaker
Thanks for the answers. What i ment is the comm board itself. See Pics.
and this:
The item you highlighted is the wifi antenna shielded by a metal case. All WiFi devices have a wifi antenna and module for wireless communication. Even in your laptop or mobile device. What would you like to know about it?
@DJ How does the IoTiny compair to the EZ-B v4 and v4/2 performance wise?
I'd like to use it to send serial commands to my arduino, which handles my navigation and add another camera. But the better the speed the faster I can load GPS waypoints and maybe add some SLAM to my project.
I'm upgrading to v4/2 in any case, the smaller format saves me from chopping up a v4
Speed and range. Are they the same? Thanks.
You bet! The EZ-B v4.x/2 and IoTiny actually run the same new TCP Stack and the application protocol layer is the same as well. The performance will be identical between the two.
The performance of READ/WRITE is incredible with the new stack and cpu. The previous version's Microchip Pic TCP stack was the best solution at the time for the first generation ez-b v4. Now, with ez-robot partnering with mxchip, the new module was customized for our needs. The new RTOS is quite impressive as well.
Remember, the READ and WRITE of any UART/Serial features will be as slow as the selected baud rate. That means a baud rate of 2400 bps will pause/buffer communication until the data has been successfully transmitted. If possible, use a faster baud rate.
The IoTiny does not have input UART, however. The IoTiny has output UART on all 8 digital pins, but no input. You would have to communicate with i2c to arduino.
