Rabid Prototypes has this week unveiled a new piece of hardware they have created in the form of the Tau, which takes the form of a tiny 32-bit Arduino Zero compatible development board.
The Tau is equipped with a 32-bit 48MHz ARM Cortex M0+ w/ 16K of RAM, and has this week launched via Kickstarter, offering an open source hardware solution as a smaller microcontroller.
Watch the video below to learn more about this open source miniature version of the Arduino zero which features a 32-bit ARM processor running at 48MHz which is far more powerful than your standard Arduino.
Tau Specifications include :
– Microcontroller: Atmel ATSAMD21E17A ARM Cortex M0+
– Clock speed: 48 MHz
– Operating voltage: 3.3V
– I/O pin limits: 3.3V, 3mA
– Digital I/O pins: 12 w/ 10 PWM channels + 2 dedicated I2C pins w/ pullups
– Analog inputs: 3 12-bit ADC channels
– Analog outputs: 1 10-bit DAC
– Flash (program) memory: 128 KB RAM: 16 KB
– Voltage regulator: TLV702, 3.5V – 5.5V input / 3.3V, 300mA output
– Dimensions: 1.1 x 0.6″ (28mm x 15mm)
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!
