While the plastic injection molds are being verified and the PCB's are being assembled for delivery, I decided to spend a little time in the EZ-B v4 firmware to see what else I could pull out of it for features... You know, to make your wait worth it While the molds are checked over for quality injections.
Well, I discovered there was just enough RAM left to add another UART/Serial TTL port for expanding modules! That's huge news - with a total of 3 High Speed UARTs on the EZ-B v4! The top speed is 3.75 Mbs per UART! That's 3,750,000 bits per second. And to top it off, each UART has an input (read) buffer of 5,000 bytes!
What does this mean? It means the ability to add additional two way peripherals to the EZ-B v4, including GPS, iRobot Roomba and more!
I'm pretty sure this little 120 MHz ARM CPU is literally running to the max right now - there's nothing else I can get it to do
- Streaming real-time audio
- Super low latency real-time video
- TCP/IP Web Server
- WiFi (ad-hoc & infrastructure with DHCP server)
- 3 x high speed i2c ports
- 3 x high speed UART ports
- 24 x Servo/Digital ports
- 8 x 12 Bit ADC Ports
- 50 x Dynamixel Chainable Connection
- High Efficiency/Low Heat Digital Switching Power Supply
All packed in a little 2 inch by 2 inch form factor... You're welcome, World!
