Arduino enthusiasts that are looking for a smaller Arduino Zero board for their next project may be interested in a new piece of hardware called the TAU that has been developed by Rabid Prototypes and which has been equipped with an Atmel ATSAMD21E17A ARM Cortex M0+ micro controller and offers 16KB RAM.
The TAU has been created to provide an affordable open source miniature version of the large Arduino Zero and offers 32-bit ARM processor running at 48MHz and can be easily programmed using the Arduino IDE.
Featuring a 32-bit ARM processor running at 48MHz, and boasting 16K of ram, the Tau is far more powerful than your standard Arduino. Like most Arduinos, the Tau features a few LEDs. A green LED lets you know that the Tau is receiving power, while a red LED is connected to pin 26 aka PIN_LED_TXL. This LED can be used as a status indicator. While I could have connected the red LED to pin 13, which is the usual pin for a status LED on an Arduino, connecting it to pin 26 avoided the need to isolate it from the SPI bus with a mosfet, and left room for the power LED!
Specification of the TAU include :
– Microcontroller: Atmel ATSAMD21E17A ARM Cortex M0+
– Clock speed: 48 MHz
