I need to understand the technical specifications of the 'Unicorn pHAT' board for a project. Please find its page on pinout.xyz and tell me how many GPIO pins it uses, the communication method for its LEDs (and if it's a one-wire protocol), and its power requirements.
Navigate to 'pinout.xyz/boards'. Scroll down and click on the 'Unicorn pHAT' board link. On the 'Unicorn pHAT' page, locate the 'Details' section to find the number of GPIO pins used and the power requirement. Examine the pinout diagram and the 'Legend' section to identify the communication method for the LEDs and confirm if it's a one-wire protocol. State the number of GPIO pins used, the LED communication method, and the power requirement.
Successfully navigates to the 'Unicorn pHAT' detailed page. States that the Unicorn pHAT uses 1 GPIO pin. States that the Unicorn pHAT uses WS2812 Data for its LEDs. States that WS2812 Data is a one-wire protocol, referencing the '1-WIRE' legend entry. States that the Unicorn pHAT requires 5V power.
