$6.00

Ang MPR121QR2 Breakout Board ay isang maginhawang interface para sa MPR121QR2 capacitive touch sensor controller ng Freescale. Nakikipag-usap ito sa I2C at kayang pamahalaan ang hanggang labindalawang indibidwal na mga electrodes. Narito ang mga pangunahing tampok at pagtutukoy:

 

Mga Tampok:

 

Capacitive touch sensor controller

I2C interface para sa komunikasyon

Kontrol para sa hanggang labindalawang indibidwal na mga electrodes

Ginawa ang ikalabintatlong elektrod

Walong LED driving pin (maaaring i-configure bilang mga electrodes o ginagamit para sa pagmamaneho ng mga LED)

Address jumper para sa pagtatakda ng I2C address (default: 0x5A)

Mga jumper para sa SDA, SCL, at interrupt na pin na may 10K pull-up resistors

Boltahe sa pagpapatakbo: 2.5V hanggang 3.6VDC

VREG pin sa 2.5V na may 0.1uF capacitor sa ground

Mga pagtutukoy:

 

Materyal: Alloy + Plastic

Application: Capacitive Touch Sensor Controller

Boltahe ng Paggawa: 2.5-3.6V

Mga sukat: 6 cm x 3 cm x 2 cm

Tandaan:

 

Ang board ay walang sariling regulasyon ng boltahe, kaya ang ibinigay na boltahe ay dapat nasa pagitan ng 2.5 hanggang 3.6VDC. Ang VREG pin ay nakatakda sa 2.5V.
