With Usb Uart And Rs485 Transceiver Also Avr Usb Programmer Schematic - atmel avr atmega644p microcontroller module with usb uart and rs485 transceiver crumb644 v1 1 avr atmega module description crumb644 v1 1 is a versatile and very pact small just 50x18mm size microcontroller module with the atmega644p microcontroller cp2102 usb uart converter and rs485 transceiver usb to rs485 converter this breakout board pairs an sp3485 rs 485 transceiver with an cp2102 usb uart ic to convert a usb stream to rs 485 the sp3485 is a half duplex transceiver so it can only municate one way at a time but it can reach transmission speeds of up to 10mbps testing of sensors with rs485 using pc without proper interface is not possible since rs232 interfaces are very rare the interface should be hooked to usb the interface between usb and rs485 can be soldered with one of the many ftdi interfaces with added rs485 driver or bought as assembled module there is always the third option.
