A tiny development board to quickly prototype RS485/Modbus devices
When building RS485/Modbus networks I have identified a need for a platform that would allow me to put various additional sensors or actuators on the network. Like relays to switch stuff, temperature, humidity sensors or other devices that don't have a native Modbus interface.
This board allows interfacing to different digital busses or analog devices.
- Robust RS485 interface
- ESD protection
- Extendable Modbus slave firmware
- I2C interface
- SPI interface
- 2 analog inputs
- PWM outputs
- 2x5 0.1' prototyping area
- Small form factor allowing PCB integration or inline integration into cable assembly
