Product Info

This module plugs into a solderless breadboard alongside a NanoCore12ST or neCore12 module, providing a USB interface and power. It features an on-board 3.3V regulator, and offers selectable 3V/5V power for your target from the USB port, with fuse protection. Compact layout, features a 2-pin power connector designed to plug directly into your breadboard's power and Ground bus strip.

Features:

• provides USB-to-TTL interface function for any TTL NanoCore12 or TTL neCore12 MCU module (not compatible with RS232 versions)
• brings out TTL levels of TXD, RXD, and DTR signals
• based on FT232R chip made by FTDI
• brings 5V from USB to power target (jumper selectable)
• on-board 3.3V regulator can supply target power for low-voltage operation
• standard miniB USB connector
• green and yellow activity LEDs provided for RX and TX monitoring
• 500mA polyfuse protects host computer's USB port from accidental shorts
• small footprint (0.725x0.85 inches; 18.5x22mm)
• 4-pin row on 0.1" centers lines up with target module pins 1 through 4 via solderless breadboard
• 2-pin power connector plugs into solderless breadboard power bus strip (compatible with most breaboards)
• jumper selectable 3.3V or 5V (or none)

Product Details

Your target board and attached circuitry can draw up to 500mA from a USB port on your computer; less, if it is plugged into a hub
