Parallax USB2SER Development Tool

The USB2SER provides an easy way to interface a PC to a microcontroller. It bridges the PC’s USB port to logic-level RX and TX signals that can connect directly to a microcontroller's I/O pins. To the PC, the USB2SER appears as a virtual COM port. To the microcontroller, the USB2SER appears as a true 5 V serial connection consisting of a RX signal, a TX signal, and a low-pulsing RESET signal controlled by ‘DTR’.

Key Features:

• USB power, no external supply required
• Four-pin female SIP connector with 0.1" spacing to interface to the microcontroller circuit
• Red and blue LEDs to indicate TX and RX activity
• Debugging embedded microcontrollers through a UART   
• Supports standard baud rates and custom rates, 300 baud to 3 megabaud
• 4.5 to 5.5 VDC
• 15 mA typical
• Full speed USB, full duplex 5 V non-inverted TTL serial from 300 baud to 57.6 kilobaud
• 1.25 x 0.47 x 0.29 in (31.8 x 12 x 7.4 mm)
• -40° to +185° F (-40° to +85° C)
