Xmega eXploreGO with ATXmega128A4U (version without MP3)

Description

Xmega eXploreGO is a module with ATXmega128A4U microcontroller, MP3 VS1003B decoder, additional DataFlash memory and microSD card connector, which can be used to build amazing projects and allow you to learn about microcontrollers from the AVR Xmega family.

It is possible to connect the Bluetooth module and the bi-directional radio module nRF24L01 . The module can be programmed via USB or program / debug using the PDI connector, led out to the edge of the board. All signals from the microcontroller have been led to external connectors. The signals connected to the VS1003B system and the additional memory have SMD jumpers, so that they can be disconnected at any time, so that they do not collide, if the signals are used for other purposes. On the edge of the PCB there is also a small ON / OFF switch for the USB power supply. The module has two configuration jumpers for selecting the power supply voltage from USB or from the VIN connector.

Xmega eXplore GO has connectors, most of them compatible with the Arduino platform , to connect extension boards designed for Arduino . Because ATXmega microcontrollers tolerate + 3.3V voltage, each signal lead has a built-in resistor of 3.6 kR, allowing connection of + 5V circuits. In some cases they may interfere, so for most of these resistors, on the opposite side of the board, there are jumpers.
