The Armadillo-43T is a complete Linux-based computer display module with built-in 24-bit color 480×272-resolution TFT LCD display, and features a Resistive Touch display. At the heart of the Armadillo-43T is a Broadcom BCM2835 System-on-Chip (SoC), which combines an ARM1176JZF-S CPU Processor with a VideoCore IV GPU in a single package. The Armadillo-43T features 512MB of RAM, which is shared between the CPU and the GPU.
A microSD card is used for booting and persistent storage. The Armadillo board does not have its own Flash memory. The datasheet explains how to install an operating system image onto your microSD card (Class 10 recommended). By default, the Armadillo has been developed to utilize the Armadillian operating system, which is based on Raspbian/Debian and optimized for the BCM2835 SoC and for the features of the Armadillo system, yet also was created to remain compatible with the Raspbian OS.
Raspbian is the operating system primarily used by the Raspberry Pi which has a large following and development community. The Armadillo, which uses the same SoC, can utilize a majority of applications written for the Raspberry Pi.
The Armadillo-43T features 13 GPIO, of which two can be used for a single I2C channel, five can be used for a single SPI channel (with two Chip Selects), and two can be used for a single Serial UART. There are also two PWM channels available, one of which is shared with the Mono Audio output via the on-board amplifier and mini speaker.
Each GPIO features clamping diodes which protect the GPIO from accidental overvoltage, typically if connected to 5V devices.
A single on-board USB A host jack is provided for connecting to devices such as keyboards, USB storage, USB hubs, WiFi, Bluetooth, Ethernet, etc.
There are three different ways that you can power the Armadillo. It has a mini-USB jack, a 2.35mm-diameter barrel jack, and a 5V input pin on its GPIO header.
