Key Features include:

• 3.5mm Pluggable block terminal connections for all pins
• RJ45 type Ethernet 100 port
• USB-A host post (for slave devices, not programming)
• Coin cell battery for continuous clock
• 16 IO pins bi-directionally level shifted to 5V (PWM, SPI, Serial, UART, DIO, AIO)
• 2  channels (4 pins) bi-directionally  level shifted to 5V (I2C, PWM, SPI, Serial, UART, DIO, AIO)
• 2 Green LEDs for state indication
