AC Adapters
Meggy Jr RGB is designed to run on batteries and classroom packs come complete with battery holders. You can also power Meggy Jr with an energy-efficient wall-plug AC adapter, 4.5 - 5 V DC, regulated, 600 mA+. These adapters are sold individually. Two versions are available: one for US/Canada, and an international multi-plug version that comes with four separate plugs. Both versions come with the appropriate power jack to solder onto the Meggy Jr circuit board.


USB-TTL Interface
An Adafruit FTDI Friend with cable or FTDI model TTL-232R-5V converter cable can be used for programming Meggy Jr RGB, Peggy 2.0, and many other Arduino compatible devices through the Arduino programming environment. One end of the cable fits into the USB port on your computer, and the other end has a 6-pin header socket that hooks up to the Meggy Jr. This is a "smart" converter that includes the USB interface chip. Sold individually.
