It is critical to use a low-dropout regulator and place a 100uF low-ESR tantalum capacitor close to the VCC pin to prevent voltage dips that could trigger a chip reset or frequency drift due to the high-power load on the internal power amplifier

EBYTE MA01-AXCX4020 ModBus RTU Serial IO Module RS485 Interface 4DI+2DO 8 Digital Outputs Rail Installation 8~28VDC FOTA [Interface signal]：RS485/RS422/RS232The Ebyte MA01 AXCX4020 supports the acquisition of 4 channel sensor switch input (DI), which is converted to serial port (RS485) and data is transmitted to configuration software or PLC. The serial port I O networking module (also known as "remote IO") that controls 2 relay switch outputs (DO) by issuing commands through the serial port to realize remote acquisition and control functions.
